Instructions For Use
Connect to the controller through a USB to RS232 module , connect the module to the PC, open the serial port debugging assistant, select the corresponding port, select the baud rate 9600, no parity, 8 data bits, 1 stop bit.
Example: To turn on all relays, send the command 55 56 00 00 00 03 06 AA, 0x5556 is the frame header, 0x000000 is the reserved byte, 0XFF is all relays, 0x06 is the command, which means multiple relays on/off operation, 0XAA As the terminator, the effect of sending the command is as shown below.
