2.3 Field wiring instructions
When multiple 485 devices are connected to the same bus,site wiring has specific
requirements,details please refer to the package,details please refer to the "485 equipment site
wiring manual.
3. Configuration Software Installation and Application
3.1 Software selection
Opening the datagram, and choosing “test software” ---- “485 parameter setting software”
and finding out and opening it.
3.2 Parameter setting
①select the right COM port (“my computer——properties——deceive manager——Port”)
and check the COM port from the Port, the name of several different kinds of 485 transmitter
drive
②connect with only one device and be powered, and click “test the baud rate” of the
software to test the device baud rate and address, the default baud rate is 4800bit/s and default
address is 0x01
③change the address and baud rate based on the application requirement, and meanwhile the
current situation of the device function can be checked
④if the test is not success, please check the device wring and 485 drive installation situation
again.

4.2 The concept of data frame format
Apply Modbus-RTU communication rules，the format below：
Initial structure ≥4 byte time
Address code = 1 byte
Function code = 1 byte
Data area = N byte
Incorrect revision = 16 byte CRC code
Ending structure ≥4 byte time
Address code：the address of the transmitter，and will be the only (factory default 0x01) in the
communication net..
Function code ：the order function orders from host computer, this transmitter only uses
function code 0x03(reading register date).
Data area ：data area is the specific communication data, attention16bits data high byte in
front!
CRC code：two byte revision code.

Temperature calculation ：
When temperature is under 0 ℃, the temperature date will be updated in complement code.
Temperature：FF9B H(Hexadecimal)= -101 => temperature = -10.1℃
Humidity calculation：
Humidity：292 H (Hexadecimal)= 658 => humidity = 65.8%RH

5. Common Problem and Solution
5.1 Device can not be connected with PLC or computer
Reasons possible:
1) Several COM ports in the computer, the port be chosen is incorrect.
2) The device address is wrong, or some device addresses are repeat.(all factory defaults are
1).
3) Baud rate, revision mode, data position and stop position are wrong.
4) The main computer and polling interval is too small and time waiting for replying is too
short, and
all need to set over 200ms.
5) The 485 general wire is broken or the A wire and B wire are connected in the wrong side.
6) Too many devices or too long wires, the power need to be chosen nearby, add 485
intensifier, and add 120Ω
