Protocol:
LC USB switch default communication baud rate: 9600Bps;
LC USB Switch Communication Protocol:
Data (1)----starting identifier (default: 0xA0)
Data (2)----Switch address code (default: 0x01, identified as the first switch)
Data (3)----Operation data (0x00 is "OFF", 0x01 is "ON")
Data (4)----check code
Example:
TURN ON: A0 01 01 A2
TURN OFF: A0 01 00 A1
HOW TO USE:
1, plug the USB relay into the computer, install the CH340 to serial port chip driver;
2, open STC-ISP, SSCOM32 and other serial debugging software, select the baud rate of 9600, send "A0 01 01 A2" turn on relay in hexadecimal (hex) form; send "A0 01" in decimal (hex) 00 " TURN OFF relay;
