Installation

Unpack the product and open the top cover.

Make cable connections accordingly.
If the product will be mounted on the wall, use the screws and dowels in the package. It starts measuring 30 seconds after the product is energized.It is recommended that the product remains in the environment for at least 5 minutes to get healthy measurement values.

Use shielded cable as communication cable to prevent signal interference from external influences.
Check the measurement values again after cable installation due to resistance created by the communication cable.

MODBUS RTU Communication Structure

RS485 Baud rate value in Modbus communication is 9600 by default. Stop bit: 1, Parity: NONE. Default Slave ID is 82.
Temperature values are kept in the holding register at address 2 (40003) and humidity values are kept in the holding register at address 3 (40004). Temperature and humidity information can be obtained by reading these registers.

INSTALLATION

Unpack the product and open the top cover.
Make cable connections accordingly.

If the product will be mounted on the wall, you can use the screws and dowels in the package.
It starts measuring 30 seconds after the product is energized. It is recommended that the product remains in the environment for at least 5 minutes to get healthy measurement values..
It is recommended to use shielded cable as communication cable as it will prevent communication signals from being affected by external influences.

Since the communication cable will create resistance, check the measurement values again after cable installation.

MODBUS RTU COMMUNICATION STRUCTURE

RS485 Baud rate value in Modbus communication is 9600 by default. Stop bit: 1, Parity: NONE.
Default Slave ID is 82.
Temperature value is kept in the holding register at address 2 (40003) and humidity value is kept in the holding register at address 3 (40004). Temperature and humidity information can be obtained by reading these registers.

Reg ster	Address	Default Value	Read Wr te	M n. Value	Max. Value
Slave ID	0 (40001)	82	R/W	1	247
Baud rate	1 (40002)	3	R/W	0	8
Temp. Val.	2 (40003)	–	R	–	–
Hum. Val.	3 (40004)	–	R	–	–

Slave ID and Baud rate can be changed via Modbus communication. For this, the desired Slave ID is written to the register with address 0 (40001), which is the register where the Slave ID is located. Likewise, if the Baud rate is to be changed, the Baud rate can be changed by writing the value for the desired Baud rate according to the table below in the register with address 1 (40002).
