Products List Samples:
WJ20-A4-485 (4-20ma input signal, output is rs485 interface)
WJ20-U1-232 (0-5V input signal,output is rs232 interface)
WJ20-U2-485(0-10V input,output is rs485 interface)
WJ20-A4-232 (4-20ma input signal, output is rs232 interface)

MODBUS RTU communication protocol:

Module default protocol is MODBUS RTU communications protocol, the default address is 01, baud rate is 9600, data format is 10bits, 1 start bit, 8bits data bit, 1 stop bit, no check.

If you forget the module address and baud rate, you can shorten INIT1(PIN 9) to INIT2(PIN 12), and then restart the module power supply, the module restored to the default state temporarily: address 01, baud rate is 9600.

Users can query the address, baud rate and communication protocol register 40201-40203, get the module actual address, baud rate and communication protocol, also you can follow the need to modify the address, baud rate and communication protocol. Please note MODBUS communication please set register 40203 to 1, otherwise it can not MODBUS communication. When the INIT1(PIN 9) is turned off to INIT2(PIN 12), restart the module power supply, the module will re-set the actual address and baud rate to run.

Support MODBUS RTU communication protocol Function Code 03(Read Holding Registers) and Function Code 06(set a single Register), command format as standard MODBUS RTU protocol.
