command Description, Please refer to '' 8 Channel  Multifunction RS485 Module commamd''
  
  
Typical applications:
 
1 AT command mode (M0 Connect), in this mode can be through the serial HyperTerminal (serial assistant) enter a simple AT command control relay. AT command mode time up to 9999 seconds 
 
 

2 MODBUS command mode (M0 disconnect), 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


It can control 1-8 channels 5V/6V/9V/12V/24V Relay Module

With RS485 interface and RS232 (TTL) interface
