2．Equipment installation instructions
2.1Inspection before equipment installation
Equipment List：
1. 1 set of temperature and humidity transmitter equipment
2. Certificate of conformity, warranty card, calibration report, etc.
3. 2 expansion plugs, 2 self-tapping screws
4. USB to 485 (optional)
5. 485 terminal resistance (gift for multiple devices)
2.2 Installation method
Wall mount
The back of the transmitter is equipped with a slide rail mounting plate. Remove the mounting plate first.
There are two expansion plugs and two self-tapping screws in the accessories. First, punch two holes with a
diameter of 5mm and a depth of ≥30mm on the wall (the opening spacing is 70mm). After inserting the expansion
plug, fix the slide rail mounting plate to the wall with self-tapping screws, and finally slide the transmitter into it.

Special Note：
1) There are certain specification requirements for 485 line field wiring. For details, please refer to the data package
"485 Equipment Field Wiring Manual".
2) When the device is connected to the 485 bus, ensure that the addresses of multiple devices will not be repeated.

2.31 Wiring instructions.
Power and 485 signal
Wide-voltage power input can be 10~30V. When wiring the 485 signal line, pay attention to the two
wires A\B not to be reversed, and the addresses of multiple devices on the bus cannot be conflicted.

turn up Just open it。
Note: When using the configuration software to change the address and baud rate, only one device can be
connected.
（The device does not provide a communication line by default, the color of the line is for reference only）
3.2 parameter settings
①. Select the correct COM port (check the COM port in "My Computer—Properties—Device Manager
—Port"). The following figure lists the driver names of several different 485 converters.
②Connect only one device alone and power it on, click the test baud rate of the software, the software
will test the baud rate and address of the current device, the default baud rate is 4800bit/s, and the
default address is 0x01.
③. Modify the address and baud rate according to the needs of use, and at the same time, you can query
the current function status of the device.
④. If the test is unsuccessful, please recheck the equipment wiring and 485 driver installation.

4.2 Data frame format definition
Using Modbus-RTU communication protocol, the format is as follows:
Initial structure ≥4 bytes of time
Address code = 1 byte
Function code = 1 byte
Data area = N bytes
Error check = 16-bit CRC code
Time to end structure ≥4 bytes
Address code: the address of the transmitter, which is unique in the communication network (factory default 0x01).
Function code: The command function instruction issued by the host, this transmitter only uses function code 0x03 (read register data).
Data area: The data area is the specific communication data, pay attention to the high byte of the 16bits data first!
CRC code: two-byte check code.
