Typical applications:




1 When controlling a module, you can use the MODUBS RTU instruction or the AT instruction. In AT command mode, the dial switch (slave address) is invalid and can only control one module at a time.

MODBUS RTU command mode (HEX), you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control

Wiring Diagram:

1 DC 12V control circuit,Wiring diagram below. ''LOAD'' may be camera,LED lights, fans, motors and other DC 12V equipment

2 DC 1-110V OR AC 85-265V control circuit,Wiring diagram below(Note:If not DC 12V load, need another DC 12V power supply). ''LOAD'' may be LED lights, fans, motors Lights, fluorescent lights, solar water heaters and other DC AC equipmen
