・Overview
The WS101LL-10M series is an integrated outdoor sensor unit with
high precision and high stability. The product is made of imported
diffused silicon chip, low power ADI professional chip and
microprocessor technology. The monitored data is output through
RS-485 interface by Modbus protocol. The WS101LL sensor unit
accepts 24VDC power input voltage

・WS101LL-10M Installation
RS485 Connection
1) Connect the 485 cable to the Modbus Host device. Notice the color code
for RS485-A (Yellow) and RS485-B (Black) connect the yellow wire to
RS485-A, and connect the black wire to RS485-B. It will malfunction if
RS485-A/B exchanged.
2) Make sure there is not Modbus ID address conflicted on the same RS-
485 Bus. ( Default: Baud Rate:9600,N,8,1 ; Modbus Slave ID:1)
*Note: RS485A line and RS485B line are strictly forbidden to contact with
the power supply line, otherwise the communication of the electrode will
be permanently damaged.
Power Input Connection
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 power input is 24VDC.

• Data Format Definition
Adopt 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
End structure ≥ 4 bytes of time
Address code: the starting address of the transmitter, which is unique in
the communication network,(Factory default 0x01).
Function code:for the function indication of the transmitter, this transmitter
only uses the function code 0x03 (read register data).
Data area: Data area is specific communication data.pay attention to the
high byte of 16 bit data is front。
CRC code: Two-byte check code.
