command Description, Please refer to ” ETD8A12 12-channel RS485 IO input and output controller commamd”

Package inlcuded:

1 x DC 12V/24V 12Ch DIO RS485/Ethernet Modbus RTU Relay Board

Typical applications:

1. The dial switch (slave address) is invalid and can only control one module at a time.

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