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.
Register map and default values table
| Reg ster | Address | Default Value | Read Write | 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).
| M n. | Max. |
| Value | Value |
| 0 | 1200 |
| 1 | 2400 |
| 2 | 4800 |
| 3 | 9600 |
| 4 | 14400 |
| 5 | 19200 |
| 6 | 38400 |
| 7 | 57600 |
| 8 | 115200 |
Press and hold the “Calibration” button to reset the changes made to the Slave ID or Baud rate to the default values. Wait until the Status (green) LED turns off (approx. 30 seconds). After the LED turns off, the button is released. Thus, Slave ID and Baud rate are returned to their default values.
CALIBRATION
- Temperature and humidity measurement, calibration cannot be done on the product. Calibration is done at the production site.
- The need for calibration due to thecommunication cable during use should be done on the control panel, not on the pr oduct.
