Typical applications:

1 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
