1. Introduction

FreeWave serial radios are DCE (Data Communications Equipment) radios that operate in

virtually any environment where data communications occur. The radios act as data transmission

devices, duplicating data in either Point-to-Point or Point-To-MultiPoint mode.

1.1. Choose a Radio Location

Placement of the FreeWave radio may have a significant impact on its performance. The key to

the overall robustness of the radio link is the height of the antenna.

When using an external antenna, placement of that antenna is critical to a solid data link. Other

antennas in close proximity are a potential source of interference.

Use the Radio Statistics to help identify potential problems. In general, FreeWave units with a

higher antenna placement will have a better communication link.

In practice, the radio should be placed away from computers, telephones, answering machines,

and other similar devices. The cable included with the radio provides ample distance for

placement away from other equipment.

Note: FreeWave offers directional and Omni-directional antennas with cable lengths ranging from 3

to 200 feet.

An adjustment as little as 2 feet in antenna placement may resolve noise issues.

In extreme cases, (e.g., Cellular Telephone tower interference) the band pass filters that

FreeWave offers may reduce out-of-bandnoise.

1.2. Choosing Point-to-Point or Point-to-MultiPoint Operation

Important!: For either a PTP or PTMP network, adding a Repeater cuts the network throughput by

50%.

1.2.1. Point-to-Point (PTP) Network

A PTP network work best when the network consists of one Master and one Slave radio.

Note: A maximum of four Repeaters can be added to extend the reach of the network.

1.2.2. Point-to-MultiPoint (PTMP) Network

In a PTMP network (also referred to as MultiPoint network) the Master radio is able to

simultaneously communicate with numerous Slave radios.

lA MultiPoint network functions with the Master broadcasting its messages to all Slave

radios.

lIf requested by the Master, the Slave radios respond to the Master when given data by the

device connected to the data port. The response depends on the setup.

lThe network reach can be extended with as many Repeaters as is required.

Example: If the network polls once a day to retrieve sparse data, several hundred Slave radios could be configured to a single Master. However, if each Slave transmits larger amounts of data or data more frequently, fewer Slave radios can link to the Master while receiving the same network performance. When larger amounts of data are sent more frequently, the overall network bandwidth is closer to capacity with fewer Slave radios.

FreeWave Technologies, Inc.

Differences between PTP and PTMP

lIn a Point-to-Point network all packets are acknowledged, whether sent from the Master to

the Slave or from the Slave to the Master.

lIn a MultiPoint network, the user determines the number of times outbound packets from

the Master or Repeater to the Slave or other Repeaters are sent.

lThe receiving radio, Slave or Repeater, accepts the first packet received that passes the

32 bit CRC. However, the packet is NOT acknowledged.

lOn the return trip to the Master, all packets sent are acknowledged or retransmitted until

they are acknowledged.

lTherefore, the return link in a MultiPoint network is generally very robust.

Traditionally, a MultiPoint network is used in applications where data is collected from many

instruments and reported back to one central site. The architecture of such a network is different

from Point-to-Point applications. These parameters influence the number of radios that can exist

in a MultiPoint network:

lData block size.

lThe longer the data blocks, the fewer number of deployed Slave radios can exist in the

network.

lBaud rate.

lThe data rate between the radio and the device it is connected to could limit the amount

of data and the number of radios that can exist in a network

lThe amount of contention between Slave radios.

lPolled Slave radios versus timed Slave radios.

lRepeater Use.

lUsing the Repeater setting in a Point-to-Point or MultiPoint network decreases overall

network capacity by 50%.

Example: If the network polls once a day to retrieve sparse data, several hundred Slave radios could

be configured to a single Master.

However, if each Slave transmits larger amounts of data or data more frequently, fewer Slave radios

can link to the Master while receiving the same network performance.

When larger amounts of data are sent more frequently, the overall network bandwidth is closer to

capacity with fewerSlave radios.

Note: Adding Repeaters to a network cuts me network rhmughput by 50%. ; ;

lExample 6 - Point-to-MultiPoint with a Repeater Site (on page 17)

1.3.1. Example 1 - Point-to-Point Gateway to Endpoint

The versatility of FreeWave radios allows data links to be established using a variety of different

configurations.

This example shows the most common and straight forward link; a Master communicating to a

Slave in a Point-to-Point link.

Figure 3: Master Communicating to a Slave in a Point-to-Point Link

1.3.2. Example 2 - Gateway Repeater Endpoint

This example shows a link using a Repeater.

lThe Repeater may be located on a hilltop or other elevated structure enhancing the link

from the Master to the Slave.

lIn this configuration, it may be desirable to use an external Omni directional antenna at the

Repeater.

lA Yagi antenna may be used at both the Master and Slave radios.

Note: Adding Repeaters to a network cuts the network throughput by 50%.

1.3.3. Example 3 - Two Repeaters

This example shows a link with two Repeaters between the Master and Slave.

lWith two Repeaters there is more flexibility in getting around obstacles and greater total

range is possible.

lIt may be desirable to use external Omni-directional antennas with the Repeaters, and

attaching a Yagi antenna to the Master and Slave radio to increase the range of the link.

lWhen two Repeaters are used no further degradation in the RF throughput of the link is

experienced.

1.3.4. Example 4 - Multiple Radios

This example shows a configuration where a Master radio routinely calls a number of Slave radios

at different times.

lThe Master radio is communicating with a radio designated as a Slave/Repeater that is

connected to a remote device.

lSince this device is placed in an elevated location, the radio may also be used as a

Repeater when it is not used as a Slave.

lAt any time the Master may call any of the Slave radios, establish a connection, and send

and receive data.

1.3.5. Example 5 - Point-to-MultiPoint

This example illustrates a standard Point-to-MultiPoint network.

lFrom the Master, any data is broadcast to all three Slave radios, one of which receives it

through a Multipoint Repeater.

lThe data is sent out of the serial port of each of the three Slave radios.

lThe end device should be configured to interpret the serial message and act on it if

necessary.

1.3.6. Example 6 - Point-to-MultiPoint with a Repeater Site

This example is a Point-to-MultiPoint network that uses one of the sites as a Slave/Repeater.

lThis network functions in the same manner as a standard MultiPoint network with

Repeaters.

lHowever, the number of radios may be reduced with the use of the MultiPoint

Slave/Repeater feature.

1.5. Identifying the Radio Model

This manual covers the configuration settings for the MM2-T,MM2-LV-T,MM2-MR-R, and MM2-

MR-T models. There are slight differences in some of the settings for each model, and important

differences in the power requirements between models. Each of these differences are described

in detail where they apply in this manual.

To identify the radio model, look at these components:

lModel number on the label

lThe model number is printed on the FreeWave label on the radio.

lConnector - The serial connector on the radio helps to identify the model.

lIf the connector has 14 pins, the radio is an MM2-T or MM2-LV-T.

lIf the connector has 10 pins, the radio is an MM2-MR-R or MM2-MR-T.

lSize

lThe MM2-T and MM2-LV-T models are the smaller of the two models, at 2 inches x

1.4inches (50.8 mm x 36 mm).

lThe MM2-MR-R and MM2-MR-T models are larger, at 2.75 inches x 2.4 inches (70 mm x

62mm).

lThe MM2-MR-R and MM2-MR-T models have a larger interface board (see below).

1.7. Powering the Radio

Connect the radio to a positive power supply with:

Model Power Supply

MM2-LV-T +3.5 VDC (± 5%)

MM2-MR +6.0 to +30 VDC

MM2-T +5.0 VDC

Warning! When using an MM2-MR model, if the power supply is above approximately +18.0 to

+20.0 VDC, use a 1ohm resistor inline with B+ input to the radio.

Note: For more information about pinouts, see MM2-MR-R or MM2-MR-T Board-Level Pinout (on

page 110).

If the power supply line runs outside the enclosure, use:

lelectrostatic discharge (ESD) protectors to protect the radio from electric shock.

ltransient voltage suppressors (TVS) to protect from an over-voltage situation.

Using both helps enhances reliable operation.

1.8. Antenna Considerations

FreeWave offers many antenna options with cables in varying lengths. Consider the following

antenna characteristics when choosing an antenna:

lAntenna radiation patterns / antenna type

lCable loss

lDirectionality

lPolarization

lPower gain

Warning! Radios with FCC ID KNYAMM0300AT on the label are required to use only Omni

antennas with 6dBi gain or less.

1.8.1. Antenna Location

When using an external antenna, placement of the FreeWave radio's antenna is likely to have a

significant impact on the radio's performance. The key to the overall robustness of the radio link is

the height of the antenna. In general, FreeWave units with a higher antenna placement have a

better communication link.

However, a higher antenna may pick up more RF noise in the area, and other antennas in close

proximity could cause interference. An adjustment as little as 2 feet in antenna placement can

Note: Use the Radio Statistics, available in option 4 in the main Setup menu of the radio to help identify problems. Example: When using an LMR 400 cable on a 200 foot tower, loss in the cable mn alone is 8 dB over the 200 foot distance. \\ ' I, To help optimize the antenna location, have FreeWave complete a Path Study.

resolve some noise problems. In extreme cases, such as when interference is due to a pager or

cellular tower, the band pass filters that FreeWave offers, may reduce this out-of-band noise.

Note: Use the Radio Statistics, available in option 4 in the main Setup menu of the radio to help

identify problems.

Also consider the following points when locating antennas:

lIdentify sites with clear Line of Sight.

lLong cable runs decrease signal and increase the amount of picked up noise.

Example: When using an LMR 400 cable on a 200 foot tower, loss in the cable run alone is 8 dB over

the 200 foot distance.

To help optimize the antenna location, have FreeWave complete a Path Study.

Complete and submit the Path Study form available from a FreeWave sales representative.

Email the completed form to pathstudy@freewave.com.

2.1. Setting the Radio's Role in the Network and the Network

Type

Networks consist of a Master radio and any number of other components including Repeaters,

Slave radios, and radios that act as both a Slave and a Repeater. The first parameter to set in a

radio is its Operation or Modem mode.

The mode tells the radio what network type it is in (Point-to-Point or Point-to-MultiPoint) and what

role it plays (Master, Slave, or Repeater) in that network.

Note: The network type must match for all radios in a network.

If configuring a Point-to-MultiPoint network, verify the Modem Mode selection for radios in the

network starts with Point-to-MultiPoint.

When setting up the radio, remember that the settings on the Master control a number of

parameters.

Therefore, deploying the Master on the communications end where it is easier to access is

advised, but not necessary.

Set the Modem mode on the Operation Mode tab, using the Modem Mode field. These settings

are available in the Operation Mode menu in the terminal interface.

Operation Mode Description

Point-to-Point

Master (0)

This mode designates the radio as the Master in Point-to-Point mode.

The Master may call any or all Slaves designated in its Call Book.

In Point-to-Point mode the Master determines the setting used for most

of the transmission characteristics, regardless of the settings in the

Slave and/or Repeaters.

The settings NOT determined by the Master are:

lHop Table settings

lRetry Time Out

lSlave Security

lTransmit Power

A quick method of identifying a Master is to power the radio.

Prior to establishing a link with a Slave, all three of the LEDs on the

Master are solid red .

Operation Mode Description Point-to-Point Slave (1) This mode designates the radio as a Slave in Point-to-Point mode. .

Description: Enables a break command to put the radio into Setup mode over the data port.

To send a break character, the end device must hold the Tx data line in the space

voltage level for longer than 1 character time.

Example: If a character is defined as having 1 start bit, 8 data bits, and 1

stop bit, the character time is 10 bits.

Thus, the transmit data line must be held in the space voltage level for a

period of time longer than 10 bits.

FREEWAVE Recommends: While the Call Book is an option in Point-to—MultiPoint networks, FreeWave strongly recommends using the Network ID feature in most applications. If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or replaced in the network, each radio in the network must be physically reprogrammed and the new serial number entered in the radios Call Book. This can be a time consuming process and can cause a delay in getting the network back up and running. Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may be added or replaced without reprogramming each Slave radio in the network. Note: For more information about defining the Call Book in a Point-to—Point network, see Using the Call Book in Point-to-Point Networks (on page 90).

2.3. Establishing Communication with Other Radios in the

Network

For the radios in the network to communicate successfully, the radios need to be told what other

devices are available for them to communicate with. Use one of these options:

lNetwork ID - Used in MultiPoint Networks, the Network ID parameter is available on the

MultiPoint Parameters tab.

lEach radio in a single network should be assigned the same ID.

lA Slave links with the first Master or Repeater that it hears that has a matching Network

ID.

lBecause the Network ID does not use serial numbers, MultiPoint Masters and

Repeaters may be replaced without reprogramming all of the Slaves in the network.

The Network ID function should be used in conjunction with the Subnet ID feature (if

necessary) to route data through the radio network.

lWithout having the serial numbers in the Call Book, Slaves may establish

communications with different Masters that match the radio's golden settings

described below, though not at the same time. This is very useful in mobile MultiPoint

applications.

lFor information about setting the Network ID parameter in a MultiPoint Network, see

Using the Network ID in MultiPoint Networks (on page 68).

lCall Book - The Call Book is required in Point-to-Point networks.

lThe Call Book stores serial numbers of other radios in the network that are allowed to talk

to a radio.

lUsing the Call Book offers both security and flexibility in determining how FreeWave

radios communicate with each other.

FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,

FreeWave strongly recommends using the Network ID feature in most applications.

If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or

replaced in the network, each radio in the network must be physically reprogrammed and the new

serial number entered in the radio's Call Book.

This can be a time consuming process and can cause a delay in getting the network back up and

running.

Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may

be added or replaced without reprogramming each Slave radio in the network.

Note: For more information about defining the Call Book in a Point-to-Point network, see Using the

Call Book in Point-to-Point Networks (on page 90).

2.3.1. Golden Settings

A standard network requires that these parameters are set the same on all radios in the network.

FreeWave refers to these as the Golden Settings:

lFrequency Key

lMin Packet Size

lMax Packet Size

lNetwork ID

lRF Data Rate

Radios that contain the same settings in all these parameters can communicate with each other.

lIf using the Call Book instead of the Network ID, or are running a Point-to-Point network,

the appropriate serial numbers must be listed in the Call Book for each radio.

lIf working with parallel Repeaters, the Frequency Key setting may differ.

2.4. Designate the RF Transmission Characteristics

The Transmission Characteristics parameters are used to change settings that determine how

data is sent between radios in the network. Many of these parameters must be maintained

throughout the network for proper functionality.

Important!: The parameters on the Transmission Characteristics tab are only for the advanced

user who has a good understanding of the principles of RF transmission.

Several settings on a Slave or Repeater radio come from the Master, and are therefore set only

at the Master. Settings that you must set on each Slave or Repeater include:

lHop Table Offset

lHop Table Size

lHop Table Version

lRetry Time Out

lSlave Security

lTransmit Power

Accept the default settings on the Transmission Characteristics tab when completing basic

setup.

However, these parameters must be set and they must be the same for all radios in the network:

lFrequency Key

lHop Table properties (Size, Version, and Offset)

lMax Packet Size

lMin Packet Size

lRF Data Rate

Set these parameters on the Transmission Characteristics tab. These settings are available in

lHopping patterns minimize the interference with other FreeWave radios

operating in the area.

Example: If 10 pairs of FreeWave radios are operating on different

networks in close proximity, setting a different Frequency Key value

reduces the chance that radios hop to the same frequency at the same

time.

If two networks were to hop to the same frequency, the next hop would be

to a different frequency for both networks.

Gain additional network separation by adjusting the Max Packet

Size and Min Packet Size parameters.

Note: Use the Hop Table Version,Hop Table Size, and Frequency

Zone parameters to define more network differentiation by limiting the

number and location of frequencies the radios may hop in the 902 to 928

MHz band.

Important!: 900MHz radios do NOT use the Hop Frequency Offset

setting.

Note: The minimum in 900MHz radios is 8 seconds. Any number between 151 and 255 in Point-to-Point networks. Terminal Menu (3) Edit TransmisSion Characteristics > (8) Retry Time Out Description: The Retry Time Out parameter in a Slave or Repeater sets the delay the unit waits before dropping the connection to a Master or Repeater. . The factory default is set at the maximum of 255. - With a setting of 255, the Master allows a Slave or Repeater to stay connected as long as 1 packet in 255 is successfully received at the Master. . The maximum setting means that if 1 packet in 255 is sent successfully from the Master to the Slave or Repeater, the link is maintained. . This allows a Slave or Repeater to drop a connection if less than 1 in 8 consecutive packets is successfully received from the Master. The Retry Time Out parameter is useful when a MultiPoint network has a roving Master or Slave. As the link gets weaker, a lower setting allows a poorlink to break in search of a stronger one. FREEWAVE Recommends: Setting the Retry Time Out parameter to l in the MultiPoint Master is recommended in areas where several FreeWave networks exist. This recommended setting allows Slaves and Repeaters to drop the connection if the link becomes too weak, while at the same time prevent errant disconnects due to interference from neighboring networks. Note: While intended primarily for MultiPoint networks, the Retry Time Out parameter may be changed in Point—to-Point networks. However, the value in Point-to-Point mode should NOT be set to less than 151.

lWith a setting of 255, the Master allows a Slave or Repeater to stay

connected as long as 1 packet in 255 is successfully received at the

Master.

lThe maximum setting means that if 1packet in 255is sent successfully from

the Master to the Slave or Repeater, the link is maintained.

lThis allows a Slave or Repeater to drop a connection if less than 1 in 8

consecutive packets is successfully received from the Master.

The Retry Time Out parameter is useful when a MultiPoint network has a roving

Master or Slave. As the link gets weaker, a lower setting allows a poor link to

break in search of a stronger one.

FREEWAVE Recommends: Setting the Retry Time Out parameter to

20 in the MultiPoint Master is recommended in areas where several

FreeWave networks exist.

This recommended setting allows Slaves and Repeaters to drop the

connection if the link becomes too weak, while at the same time prevent

errant disconnects due to interference from neighboring networks.

Note: While intended primarily for MultiPoint networks, the Retry Time

Out parameter may be changed in Point-to-Point networks.

However, the value in Point-to-Point mode should NOT be set to less than

151.

Note: In MultiPoint networks, the RF Data Rate parameter must be set the same in all radios. Any radio With an RF Data Rate setting different from the Master Will not establish a link. In F'oint—to- F'oint networks the Master setting takes precedence overthe Slave. RF Data Rate (Golden Setting) Setting Description Default Setting (3) Normal Options .

RTS to CTS

Setting Description

Description: Use this option to set the RTS line on the Master radio to control the CTS line of

the Slave.

With RTS to CTS enabled:

lIn MultiPoint networks, the Master RTS line controls all Slave's CTS lines.

lThe CTS line stops functioning as flow control.

lThe Master senses the RTS line prior to all scheduled packet transmissions.

lIf the state has changed, the Master then transmits a message to the Slave

with the new status. This transmission occurs regardless of data being

sent.

lIf data is ready to be sent, the RTS status message is sent in addition to the

data.

lIn Point-to-Point mode, the Master continues sending the new status message

until it receives an acknowledgment from the Slave.

lIn MultiPoint mode, the Master repeats the message the number of times

equal to the Master Packet Repeat value in the MultiPoint Parameters tab.

lMaster transmit times are completely asynchronous to the occurrence of any

change of the RTS line; the latency time from RTS to CTS is variable.

lThe Max and Min Packet Size parameters determine this duration.

lSetting both parameters to their maximum value of 9produces a maximum

latency time of approximately 21ms, given no Repeaters in the network.

lAt the minimum settings for Max and Min Packet Size (0), the time is

approximately 5.9ms.

lThis latency can increase significantly if packets are lost between the Master

and Slave.

lIn Point-to-MultiPoint mode, no absolute guarantee is made that the state

change is communicated to all Slaves.

lIn MultiPoint networks with Repeaters present, the latency is cumulative for

each serial Repeater.

Example: If the latency between the Master and the first Repeater is

15ms, and two serial Repeaters are present, the total latency is 45ms.

(M—R1 (15ms) + R1—R2 (15ms) + R2—S (15ms) = 45ms).

Important!: The RTS to CTS feature does NOT function in Point-to-Point

networks that contain a Repeater.

If this feature is needed in such network, the mode should be changed to

Point-to-MultiPoint.

lIf DTR Connect on the Tool Suite MultiPoint Parameters tab is enabled and

set to 2, the RTS to CTS feature does not work.

3. Configuring

Point-to-MultiPoint Networks

When installing MultiPoint networks it is important to do some up front planning around the

devices to implement and the route the data is going to take back to the Master. A MultiPoint

network can contain the following devices:

lOnly one Master. All communications are from and to the Master.

lAn unlimited number of Slave radios (remote sites).

lAn unlimited number of Repeaters between any Slave and the Master.

lSerial Repeaters can be Slave radios and Repeaters at the same time.

This section provides details about the setup that applies specifically to a MultiPoint network:

lPoint to MultiPoint network characteristics.

lUsing the Network ID or the Call Book to establish which radios in the network can

communicate with each other.

lUsing subnet IDs to route traffic through the network, back to the Master.

lSettings and recommendations for additional parameters that apply to a MultiPoint

network.

lConserving power in devices within the network.

lRunning network diagnostics.

Note: See Routing Communications through the Network (on page 71) and Assigning Subnet ID

Values (on page 71) for additional information.

3.1. Point to MultiPoint Network Characteristics

A Point to MultiPoint network has these unique characteristics:

lGolden Settings (on page 63).

lMaster to Slave Communications (on page 63).

lSlave to Master Communications (on page 63).

3.1.1. Golden Settings

A Point-to-MultiPoint network requires that the Golden Settings (described in Golden Settings (on

page 44)) are set the same on ALL radios in the network.

If several independent MultiPoint networks are located in close proximity, the planning becomes

more critical. It is very important to include as much frequency and time diversity as possible using

different Min and Max Packet Size. In some instances the use of the MultiMaster Sync option

may be required.

In almost all MultiPoint networks, the Frequency Key is the same for all radios. In other networks,

where parallel Repeaters are introduced, the Frequency Key value needs to change.

3.1.2. Master to Slave Communications

Master - to - Slave communications within a MultiPoint network have these characteristics:

lData packets sent from the Master include a 32-bit CRC.

lThe Master repeats its data broadcast between 0 to 9 times, depending on the Master

Packet Repeat setting. For more information, see Master Packet Repeat (on page 78).

lA Slave or Repeater does not send acknowledgments to the Master when it receives data.

lWhen any Slave in the network receives the data packet from the Master with the 32-bit

CRC, that Slave ignores any additional repeats of the data, and passes the data to its

data port.

lRepeaters in the network send data to Slave radios and other Repeaters.

3.1.3. Slave to Master Communications

Slave - to - Master communications within a MultiPoint network have these characteristics:

lData packets sent from the Slave to the Master include a 32-bit CRC.

lWhen the Master successfully receives data, it sends an acknowledgment to the Slave and

passes the data out its data port.

lmportantl: Power supply ranges and recommendations vary depending on model. Verify the specifications fortne model pnorto connecting power. Note: A MultiPoint network can have only one Master, unless running in Mum-Master Sync mode. For more information, see Multi-Master Sync (on page 103).

3.4. Overlapping MultiPoint Networks

Overlapping MultiPoint networks may be set up effectively when several key parameters are set

correctly. Overlapping MultiPoint networks are defined as networks using different Master radios,

which share or overlap in a specific geographic area. It may also include collocated radios

configured into different networks.

For more information, see Application Note #5412, Synchronizing Collocated Masters (Multi-

Master Sync Mode) (available from www.freewave.com).

Collocated MultiPoint networks require these parameters be unique for each network:

lNetwork ID (unless using the Call Book)

lFrequency Key (with Repeater Frequency)

lMax Packet Size

lMin Packet Size

Note: For more information about the installation of Point-to-MultiPoint networks, contact FreeWave

Technical Support.

See Contact FreeWave Technical Support on page 9

3.5. Establishing Communication with Other Radios in a

MultiPoint Network

For the radios in the network to communicate successfully, the radio needs to know what other

devices are available for them to communicate with. Use the Network ID or the Call Book.

FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,

FreeWave strongly recommends using the Network ID feature in most applications.

If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or

replaced in the network, each radio in the network must be physically reprogrammed and the new

serial number entered in the radio's Call Book.

This can be a time consuming process and can cause a delay in getting the network back up and

running.

Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may

be added or replaced without reprogramming each Slave radio in the network.

3.5.1. Using the Network ID in MultiPoint Networks

The Network ID parameter is located on the MultiPoint Parameters tab. In a single network,

assign each radio the same Network ID. Slave radios link with the first Master or Repeater it

hears that has a matching Network ID.

When setting the Network ID:

lThe value can be any value between 1 and 4095, except 255.

l255 enables the Call Book.

Example: Use the last four digits of the Master serial number if it is below 4095. This is ensured to be unique and does not overlap with other nearby FreeWave networks. FREEWAVE Recommends: While the Call Book is an option in Point-to—MultiPoint networks, FreeWave strongly recommends using the Network ID feature in most applications.

lTo help ensure the ID is unique to the network, avoid using numbers that coincide with

nearby landmarks or highways.

Example: Use the last four digits of the Master serial number if it is below 4095.

This is ensured to be unique and does not overlap with other nearby FreeWave networks.

lUse the Network ID function in conjunction with the Subnet ID feature (if necessary) to

route data through the radio network.

3.5.2. Using the Call Book in MultiPoint Networks

Although NOT recommended, the Call Book is an option in MultiPoint networks. If the Network

ID feature is used in a MultiPoint network, no entries are needed in the Call Book of any of the

radios.

FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,

FreeWave strongly recommends using the Network ID feature in most applications.

If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or

replaced in the network, each radio in the network must be physically reprogrammed and the new

serial number entered in the radio's Call Book.

This can be a time consuming process and can cause a delay in getting the network back up and

running.

Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may

be added or replaced without reprogramming each Slave radio in the network.

Important!: Using the Call Book in a MultiPoint network can cause delay in resuming

communications if a Master is damaged.

Note: For information about setting the Call Book, see Using the Call Book in Point-to-Point

Networks on page 90.

In a MultiPoint network, the Slave radios and Repeaters are not listed in the Master radio's Call

Book. Slave radios must have the Master and any Repeater it is going to use in its Call Book.

These examples show the Call Book of a MultiPoint network comprised of a Master, Repeater,

and Slave in which the Slave can communicate either through the Repeater or directly to the

Master.

3.5.3. Programming Point-to-MultiPoint Extended Call Book

In a MultiPoint network, Slave radios can be programmed to roam between Master radios and

Repeaters using the MultiPoint Extended Call Book function. Slave radios with Call Book, as

configured in this procedure, communicate with any radio whose serial number appears in any of

the three columns.

Procedure

1. Set the Network ID to 255.

2. In the Call Book, enter 999-9999 as the last entry in the first and second columns.

3. In the Call Book, set Entry to Call to All.

Figure 23: HyperTerminal PTMP Extended Call Book

Note: Forcing the communications path optimizes the performance of the network by ensuring the Repeater or Slave links to a Repeater or Master with robust RF communications. Subnel IDs can help to minimize latency.

3.6. Routing Communications through the Network

When using the Network ID, a Repeater or Slave links to the first Repeater or Master it hears

with the same ID.

lUse Subnet IDs to determine the path a Repeater or Slave uses to communicate back to

the Master.

lSubnet IDs are particularly helpful to force:

lTwo Repeaters in the same network to operate in series rather than in parallel.

lSlave radios to communicate to a specific Repeater for load balancing purposes.

Note: Forcing the communications path optimizes the performance of the network by ensuring the

Repeater or Slave links to a Repeater or Master with robust RF communications. Subnet IDs can

help to minimize latency.

3.6.1. Assigning Subnet ID Values

Subnet IDs consist of two parts, both available on the MultiPoint Parameters tab:

lRx - This setting identifies which radio a Repeater or Slave listens to.

lIn the terminal interface, this is the Rcv Subnet ID.

lTx - This setting identifies the ID this device transmits on and which devices listen to it.

lThe Tx Subnet ID parameter is relevant for MultiPoint Master radios and Repeaters

only.

lIn the terminal interface, this is the Xmt Subnet ID.

lThe default (disable) setting for both Rx and Tx is F, F.

lThis is a visual way to indicate that the device is the final in the line of communication and

does not use a subnet ID.

lA MultiPoint Slave with a Subnet ID of F, F does not roam from one Repeater or network

to the next.

lIt only links to a Master or Repeater that has either a Transmit Subnet setting of 0or an

F, F Subnet ID.

lSetting both Rx and Tx Subnet ID to 0allows a mobile Slave to roam from subnet to

subnet, and possibly from network to network, provided the Network ID,Max and Min

Packet Size, and RF Data Rates are the same between networks.

The examples in this section show the subnet definitions from the Master radio through the

network to the Slave radios. When the subnet path is defined, the Slave radios can follow the

route back to the Master.

Calibrate a Slave Radio in 1PPS Enable/Delay Mode

1. On the Master radio, trigger an oscilloscope on the 1 PPS pulse on the DTR line.

2. Monitor the CD line of the Slave radio.

3. If the timing on the Slave radio differs from the Master it may be adjusted via the value in the

Slave radio's 1 PPS Enable/Delay parameter.

The difference in time between each incremental integer value is 542.534 nanoseconds (ns).

Changing the parameter to higher values decreases the Slave radio time delay and changing the

parameter to lower values increases the time delay.

When properly calibrated, the CD line Slave radio outputs a pulse that goes high for about 2 ms in

sync with the 1 PPS pulse on the Master radio. The output on the Slave radio occurs within 20

microseconds of the input to the Master.

Note: When usrng the radio in Modbus RTU mode, the Master Packet Repeat setting must match in every radio, regardless of whether the network is in Potnt-to—Point or MultiPoint mode. Master Packet Repeat Setting Description Default Setting 3 Options Any number between 0 and 9. Terrmnal Menu (5) Edit MultiPoint Parameters > (1) Master Packet Repeat Description: In a Point—to-MultiPoint network, Slave radios do not acknowledge transmissrons from the Master. . If Slave radios did acknowledge all data transmissrons, in a large network, the Master would soon become ovenrvhelmed with acknowledgments from the Slaves. . Without acknowledgments, 100% confidence every Slave radio has received every packet cannot be met. . To address this issue, change the Master Packet Repeat parameter, assrgning a value between I (the packet IS transmitted once) tol (the packet is transmitted 10 times). For networks with solid RF links, this parametershould be set to a low value (e.g., IorI)- . If a network has some weak or marginal links it should be set with higher values. . If a Slave radio receives a good packet from a Master more than once it discards the repeated packets. . Similarty, aftera MultiPoint Repeater receives a good packet from the Master, it discards any further repeated packets. . In tum, the Repeater sends the packet out to the next Repeater or Slaves the number of times corresponding to its own Master Packet Repeat setting. Increasrng the Master Packet Repeat setting increases the probability of a packet getting through, but also increases latency in the network because each packet from the Master or Repeater IS being sent multiple times. Note: Therefore, it is important to find the optimal mix between network robustness, throughput, and latency. In general, a setting ofl tol works well for most well designed networks. The Master Packet Repeat parameter may be set to I if the user software is capable of, or requires acknowledgment. In this case, If the Master sends a packet that the Slave radio does not receive, the user software controls the retnes as needed.

Note: When using the radio in Modbus RTU mode, the Master Packet Repeat setting must match

in every radio, regardless of whether the network is in Point-to-Point or MultiPoint mode.

Master Packet Repeat

Setting Description

Default Setting 3

Options Any number between 0 and 9.

Terminal Menu (5) Edit MultiPoint Parameters > (1) Master Packet Repeat

Description: In a Point-to-MultiPoint network, Slave radios do not acknowledge transmissions

from the Master.

lIf Slave radios did acknowledge all data transmissions, in a large network, the

Master would soon become overwhelmed with acknowledgments from the

Slaves.

lWithout acknowledgments, 100% confidence every Slave radio has received

every packet cannot be met.

lTo address this issue, change the Master Packet Repeat parameter,

assigning a value between 0(the packet is transmitted once) to 9(the packet

is transmitted 10 times).

For networks with solid RF links, this parameter should be set to a low value (e.g.,

1or 2).

lIf a network has some weak or marginal links it should be set with higher

values.

lIf a Slave radio receives a good packet from a Master more than once it

discards the repeated packets.

lSimilarly, after a MultiPoint Repeater receives a good packet from the Master,

it discards any further repeated packets.

lIn turn, the Repeater sends the packet out to the next Repeater or Slaves the

number of times corresponding to its own Master Packet Repeat setting.

Increasing the Master Packet Repeat setting increases the probability of a

packet getting through, but also increases latency in the network because each

packet from the Master or Repeater is being sent multiple times.

Note: Therefore, it is important to find the optimal mix between network

robustness, throughput, and latency.

In general, a setting of 2to 3works well for most well designed networks.

The Master Packet Repeat parameter may be set to 0if the user software is

capable of, or requires acknowledgment.

In this case, if the Master sends a packet that the Slave radio does not receive,

the user software controls the retries as needed.

Example: If a Master's Master Packet Repeat parameter setting is I the link between the Master and Repeater should be robust. If the Repeater‘s Master Packet Repeat parameter setting is I this could cause marginal links between the Repeater and the Slaves. The Slaves communicating through this Repeater only receive the initial packet from the Master with no repeats. Therefore, if the packet is not received on the ﬁrst try, the Slave radio does not respond as expected. Note: The Master Packet Repeat parameter setting in any MultiPornt Repeater must be less than or equal to the Masters setting. Max Slave Retry Setting Description Default Setting 9 Options Any number between ’l and 9. Terminal Menu (5) Edit Multhoint Parameters > (2) Max Slave Retry Description: . Defines how many times the Slave radio attempts to retransmit a packet to the Master before beginning to use a back—off algorithm as defined by the Retry Odds on page 81 setting. .

3.7.6. Master Packet Repeat in MultiPoint Networks with Repeaters

The Master Packet Repeat parameter must be set in MultiPoint Repeaters because a Repeater

appears as a Master to a Slave radio.

Therefore, the Repeater sends the packet out the number of times corresponding to its own

Master Packet Repeat parameter setting. If this parameter is set improperly the reliability of the

overall network may be diminished.

Example: If a Master's Master Packet Repeat parameter setting is 3, the link between the Master

and Repeater should be robust.

If the Repeater's Master Packet Repeat parameter setting is 0, this could cause marginal links

between the Repeater and the Slaves.

The Slaves communicating through this Repeater only receive the initial packet from the Master with

no repeats.

Therefore, if the packet is not received on the first try, the Slave radio does not respond as expected.

Note: The Master Packet Repeat parameter setting in any MultiPoint Repeater must be less than

or equal to the Master's setting.

Retry Odds

Setting Description

Description: While packets transmitted from the Master to the Slave radios in a MultiPoint

network are not acknowledged, packets transmitted from Slaves to the Master are

acknowledged.

It is possible that more than one Slave attempts to transmit to the Master at the

same time. Therefore, it is important that a protocol exists to resolve contention

for the Master between Slaves in the network.

This is addressed through the Max Slave Retry (on page 79) and Retry Odds

parameters.

lAfter the Slave has unsuccessfully attempted to transmit the packet the

number of times specified in the Max Slave Retry parameter, it attempts to

transmit to the Master on a random basis.

lThe Retry Odds parameter determines the probability that the Slave attempts

to retransmit the packet to the Master; a low setting assigns low odds to the

Slave attempting to transmit.

lConversely, a high setting assigns higher odds.

Example: Consider two different Slave radios in a MultiPoint network,

one with a strong RF link and the other with a weak RF link to the

Master.

If a Slave has a weak or poor link, set the Retry Odds parameter to 0

as it may become a chatty Slave and lockup the network, causing a

loss of communication.

lWhen the Retry Odds parameter is set to 0, after the Slave has exhausted the

number of retries set in the Max Slave Retry parameter and still not gained the

Master’s attention, the Slave’s data buffer is purged.

3.8. Reading Diagnostics in Tool Suite

The Network Diagnostics application provides a place to view diagnostic data for all the devices

connected to the Master in the network in real time.

Important!: The Network Diagnostics application is NOT meant to replicate the functionality of a

Network Management System.

It is a tool intended for occasional network monitoring or troubleshooting in the field, not for

continuous, long-term collection of diagnostic data.

This section provides basic steps for reading diagnostics using Tool Suite. Tool Suite stores the

diagnostic data in the database for import from or export to a diagnostic file.

For information regarding the data available, recommended best practices, and importing and

exporting files using the Network Diagnostics application, see the Tool Suite User Manual

available in the Tool Suite software.

To help identify the radios in the network when running Network Diagnostics, set the Radio

Name and Radio ID fields on the MultiPoint Parameters tab.

The diagnostic program must be run from the Master radio. Diagnostics require:

lA setting between 1 and 128 in the Diagnostics parameter available in the MultiPoint

Parameters menu on the Master.

lA second computer or serial connection to run the diagnostics software.

lA diagnostics cable. (Available from FreeWave.)

lDiagnostics software. (Available from www.freewave.com).

Note: For more information about diagnostics, contact FreeWave Technical Support.

Contact FreeWave Technical Support (on page 9) for assistance.

Note: The Network Diagnostics application continues to poll for diagnostic data until it is stopped. lmponantl: Tool Suite is NOT optimized for the collection and management of large amounts of diagnostic data from continuous polling. Collection of excesswe amounts of data results in overall performance degradation in Tool Suite and network throughput degradation.

lmponantl: The Call Book is required in Foint—to-Point networks. FREEWAVE Recommends: While the Call Book is an option in Point-to—MultiPoint networks, FreeWave strongly recommends using the Network ID feature in most applications. If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or replaced in the network, each radio in the network must be physically reprogrammed and the new serial number entered in the radios Call Book. This can be a time consuming process and can cause a delay in getting the network back up and running. Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may be added or replaced without reprogramming each Slave radio in the network. Note: To set the Entry to Call option in the terminal interface, press at the Call Book menu, followed by the menu number corresponding to that Slave. To call any available Slave in the list, press then press to direct the Master to Call All. Note: When entering numbers into the Call Book, define only the Repeaters in the Masters Call Book. The Slave‘s Call Book only requires the Master serial number. A Repeater need not have anything listed in its Call Book.

Using the Call Book offers both security and flexibility in determining how FreeWave radios

communicate with each other.

Important!: The Call Book is required in Point-to-Point networks.

FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,

FreeWave strongly recommends using the Network ID feature in most applications.

If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or

replaced in the network, each radio in the network must be physically reprogrammed and the new

serial number entered in the radio's Call Book.

This can be a time consuming process and can cause a delay in getting the network back up and

running.

Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may

be added or replaced without reprogramming each Slave radio in the network.

lThe Call Book allows a maximum of 10 FreeWave radios.

lDesignate 1 to 4 Repeaters to use with each radio.

lDesignate which Slave the Master calls.

These settings are required for two FreeWave radios to communicate in Point-to-Point mode:

1. The Master radio serial number must be listed in the Slave radio's Call Book or Slave

Security is turned off in the Slave.

2. The Slave serial number must be listed in the Master Call Book .

3. The Master must be programmed to call the Slave (Entry to Call option).

a. Select the number in the Entry to Call field, select All to direct the Master to call all

Slave radios.

Note: To set the Entry to Call option in the terminal interface, press <C> at the Call Book

menu, followed by the menu number corresponding to that Slave.

To call any available Slave in the list, press <C> then press <A> to direct the Master to Call

All.

It is important that the Call Book slots (0-9) are filled sequentially starting with slot 0.

lWhen a Master is instructed to Call All, it calls all Slave radios listed until it reaches the first

serial number of 000-0000 (or a blank slot).

lIf a serial number is entered after the all zero number or as a Repeater, the Master does not

recognize it as a valid number.

Note: When entering numbers into the Call Book, define only the Repeaters in the Master's Call

Book.

The Slave's Call Book only requires the Master serial number.

A Repeater need not have anything listed in its Call Book.

4.3.3. Programming Point-To-Point Extended Call Book to Use Three or

Four Repeaters

In a Point-to-Point configuration, FreeWave radios can use a maximum of four Repeaters.

1. To use three or four Repeaters, program the Call Book with the Slave serial number,

followed by the first two Repeaters.

2. On the next line enter 999-9999 as the radio to call.

Figure 28 shows a Point-to-Point link where a Slave is called through four Repeaters. In this

example:

lthe Master is calling the Slave, 571-3872, through Repeater 1, 901-1234,

lthen Repeater 2,910-0234,

lthen Repeater 3, 571-3456, and finally

lRepeater 4, 571-4567.

lEntering the serial number 999-9999 in line 1 instructs the Master to continue calling

through the Repeaters programmed on that line.

Figure 28: Point-to-Point link where a Slave is called through four Repeaters

lTo call a Slave radio through one or more Repeaters, that Slave must be called individually.

lWith Call All selected, the Master will not connect with any Slave radios through

Repeaters.

lThe Master calls every Slave in the list and connects with the first Slave that responds.

lWhen calling through a Repeater, the Master must first call that Repeater and establish a

communications link with it prior to making contact with the Slave.

5.1. Working with Parallel Repeaters

When Repeaters are added to a network, plan accordingly to avoid creating a parallel Repeater

scenario. A parallel Repeater is defined as two or more Repeaters linked to the same point in the

network.

lRepeaters Data Transmitted on the Same Frequency Key (on page 95)

lAdding a Repeater to the Network (on page 96)

5.1.1. Repeaters Data Transmitted on the Same Frequency Key

In this diagram, the Slave radio in the middle has overlapping coverage from both the Repeaters

(parallel Repeaters). Data from the Repeaters is transmitted on the same Frequency Key in the

same time slot, which creates message collisions.

Figure 29: Slave Radio with Overlapping Coverage

To resolve this scenario, change these settings on one or more of the Repeaters in conflict:

5.3. Enable and Set Up AES Encryption

Protecting the confidentiality, integrity, and authenticity of data communications is essential to

maintaining a robust, reliable, and secure wireless infrastructure. FreeWave has incorporated a

number of mechanisms to achieve these critical security objectives, including the use of AES

encryption. When available and enabled, AES encryption adds a layer of 128-bit, 192-bit, or 256-

bit encryption strength to the data before it is sent over the RF link.

Note: AES encryption is available as an option set at the factory in firmware v10.6.6 and later in

some MM2-MR, MM2-LV-T, MM2-T models.

When using AES encryption, these settings are required:

lEncryption Channel Key (on page 102).

lEncryption Key (on page 100).

lEncryption (Strength) (on page 99).

lmportantl: These settings are ONLY available in the (3) Edit Radio Transmission Characteristics > (E) Encryption menu in the terminal interface. These settings are NOT available in Tool Suite. Note: For information about accessing the Setup menu using the terminal interface, see Access the Setup Menu Using a Terminal Emulator (on page 27). lmportantl: When AES is enabled, every radio in the network must have matching encryption strengths, encryption keys, and encryption channel keys, and the MCU Speed parameter set to I for successful communication and data transmission. Note: AES encryption settings are available only through the Setup menu in the terminal interface.

Important!: This option is only used for peer-to-peer communications or when applications are very

time specific. If you purchase TDMA as an option, additional information is provided to you about

implementing and using the feature.

6. Viewing Radio Statistics

When reading a radio, the system shows data transmission statistics the radio has gathered

during the most recent session. This information is valuable to know the signal strength and noise

levels of the link. Statistics are gathered during each time the Master and Slave link and are reset

when the next link begins.

More data transmission characteristics are available, including averages gathered over time, in

the Network Diagnostics application.

Note: For information about running network diagnostics see the Tool Suite User Manual.

6.1. Antenna Reflected Power

Note: This statistic is not valid in the MM2-MR, MM2-LV-T, MM2-T radios.

6.2. Noise Level

The Noise Level indicates the level of background noise and interference at this radio and at

each of the Repeaters in the link. The number is an average of the noise levels measured at each

frequency in the radio’s frequency hop table.

The individual measurement values at each frequency hop channel are shown in the 900MHz

Frequency Zones Table (on page 50).

If viewing statistics in the terminal interface, press <Enter> when the Radio Statistics menu

appears.

lIdeally, the difference between the average signal level and average noise level should be

15 or more.

lMargins that are significantly higher than this are an indication of a high level of interference

that may degrade the performance of the link.

6.3. Number of Disconnects

The value in this statistic indicates the total number of times the link between the Master and the

Slave has been lost and the radios lose Carrier Detect from the time the radio is powered on until

the radio is put into Setup mode.

lUnder ideal operating conditions, the number of disconnects should be 0.

lOne or more disconnects may indicate a weak link, the presence of severe interference

problems, or loss of power to any of the radios in the link.

Note: In Tool Suite, the disconnect information is available in the Summary View under Network

Diagnostics.

6.4. Radio Temperature

The Radio Temperature value is the current operating temperature of the radio in degrees

Celsius.

6.5. Rate % (Receive Percentage Rate)

The Rate % measures the percentage of data packets that were successfully transmitted from the

Master and received by the upstream radio on the first attempt. The rate percentage represents

only what the upstream radio received.

lA number of 75 or higher indicates a robust link that provides very good performance even

at high data transmission rates.

Note: Many settings can impact actual throughput, including Master Packet Repeat and Max Slave Retry. If the link is asymmetrical, the percentage reported in this statistic can be very high, and the uplink can still be poor. \ I I The individual measurement values at each frequency hop channel are shown in the 900MHz \ ’ Frequency Zones Table (on page 50). v If viewing statistics in the terminal interface, press when the Radio Statistics menu ' appears. ‘ Note: This statistic is not valid in the MM2—MR, MMZ-LV-T, MMZ-T radios.

lA number of 15 or lower indicates a weak or marginal link that provides lower data

throughput.

lThroughput is reduced by 50 percent if the network contains a Repeater.

Note: Many settings can impact actual throughput, including Master Packet Repeat and Max Slave

Retry.

If the link is asymmetrical, the percentage reported in this statistic can be very high, and the uplink

can still be poor.

6.6. Signal Level

The Signal Level indicates the level of received signal at the radio and at each of the Repeaters

in the link.

lThe source of the signal is the radio that transmits to the radio reading this statistic.

lThe number is an average of the received signal levels measured at each frequency in the

radio's frequency hop table.

lFor a reliable link, the margin should be at least 15 dB.

lLow average signal levels can often be corrected with higher gain antennas, better antenna

placement and/or additional Repeaters.

The individual measurement values at each frequency hop channel are shown in the 900MHz

Frequency Zones Table (on page 50).

9.1. Version v10.7.04

Release date: December 2016

Additions and Changes

lA hidden Option 4 has been added to the Hop Table Parameters menu. This option:

lprovides another mechanism to set channel restrictions.

lallows users to mask out individual or blocks of frequencies (channels).

lSee 900MHz Channel Select Parameters (on page 45) for detailed information.

Note: The original implementation is limited to a finite number This functionality is maintained

to support backwards compatibility.

lThe Single Channel Mask process is used instead of the Zones method by using two

array masks.

lThe first array is the Master Channel Array (MCA) and is created via an order option and

is programmed into the unit at FreeWave.

lThe second array is the Customer Channel Array (CCA) and can be created by the

customer.

lThe CCA cannot unmask channels that are masked by the MCA but can mask out

channels that are not restricted by the MCA.

lAdded a new option to legacy MM2-MR, MM2-LV-T, MM2-T radios to use a channel select

for each channel.

lWhen enabled, this overrides the Zone mask.

Note: The current selectable frequency tables and the zone filter remain the same to allow for

backwards compatibility.

Additions and Changes

lThis firmware is provided for the MM2 models to stay in sync with firmware updates made

for the FreeWave FGR2 product line, which shares the same firmware. This firmware

version corrects a problem with serial radios set to RS485 changing to RS232 operation

with no settings change. The MM2 models run only in RS232, so this fix does not apply.

Known Limitations and Workarounds

lIn the Network Diagnostics application in Tool Suite, the radios report having the

incorrect firmware version installed.

lOn the Operation Mode tab in Tool Suite (Modem Mode menu in the terminal interface),

Ethernet parameters appear.

lThese options do not apply to this radio.

lSupply voltage readings in Tool Suite can fluctuate and differ from those readings on an

external voltage meter.

lIn the Transmission Characteristics tab in Tool Suite (Edit Transmission

Characteristics menu in the terminal interface), the Serial Interface parameter includes

RS422, RS485, and RS232. The only valid option is RS232.

9.4. Version v10.6.6

Release Date: October 2012

Additions and Changes

lUpdated firmware version to use the vX.X.X format.

lAdded AES 128, 192, and 256 encryption capability. AES functionality is enabled at the

factory. To upgrade an existing radio to use the AES functionality, contact FreeWave

Technical Support.

lAES options MUST be set using the terminal interface.

lTool Suite versions 2.9.0.0 and earlier do NOT include AES.

lRemoved the Ultra Low Power Mode feature.

Known Limitations and Workarounds

lIn the Network Diagnostics application in Tool Suite, the radios report having the

incorrect firmware version installed.

9.5. Version 8.78

Release Date: December 2011

Additions and Changes

lAES zeroization - AES capability now supports zeroization, attempting to hold to NAVSO

P5239, and various locks and checks against zeroized keys.

lClear 8th data bit when set to 7 data bits - In a case where one radio is programmed

with 7 data bits, and parity enabled, the parity bit is transferred by the radios as the 8th data

bit, and sent out the port on the other side. This corrupts the data. Now if the radio is set to 7

data bits, it clears the 8th data bit on serial receive.

lRepeater un-shifts timing in OTA slot - Repeaters shift half of their timing to ensure

their transmissions lineup exactly in time with the masters (2nd layer deep). During an over

the air firmware upgrade, the repeater shifted half of it's timing, but did not unshift the

timing. This could build into a timing problem causing drop of link on sufficient missed

packets.

lUltra Low Power Mode -ULPM Enable and ULPM Sleep parameters now available in

the Transmission Characteristics settings. For more information about Ultra Low Power

Mode, see the Parameter Reference chapter in this manual.

9.6. Version 8.77
