・Overview
The ES105M series is an intergraded outdoor sensor unit for
multiple gas sensors. The monitored data is output through RS-485
interface by Modbus protocol. The ES105M sensor unit accepts
10~30Vdc power input voltage and is protected by the IP65 grade
Anti-U/V lightweight ABS louver radiation shield. With the optional
NBIoT/WiFi gateway WR222 or LoRa end node LC144, the data can
be monitor on the cloud platform.

Wiring The RS485 Signals
1) Connect the cable to the device, connect the yellow wire to
RS485-A, and connect the blue wire to RS485-B.
2) When wiring the RS485 cable, pay attention to A/B the two lines
cannot be reversed.
3) Make sure the addresses of multiple devices on the Modbus
setting do not conflict.
*Note: When polling, the RS485 Modbus RTU needs polling
interval time(≥300mS)
Wiring The Power Input
DC 24V (Range 10 ~30V)
1) Connect the power cable to the device. Brown cable is the
positive pole of the power supply and black cable is the negative
pole of the power supply.
2) Connect the power wires to suitable DC Switching type power
supply. The input range, please check the label information
attached on the cable
*Note: After the sensor is powered on, it requires a warm-up
time(≥5 minutes) to stabilize the measurement data

Data Format Definition
Adopt Modbus-RTU communication protocol, the format is as follows:
Initial structure ≥ 4 bytes of time
Unit: mm
Address code = 1 byte
Function code = 1 byte
Data area = N bytes
Error check = 16-bit CRC code
End structure ≥ 4 bytes of 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.
Data area: Data area is the specific communication data, attention16bits
data high byte in front!
