Instructions for use
Step 1: Connect the LSB relay module to the computer and install the driver of CHH340USB to serial chip. Step 2: Open STC-ISP, SSCOM32-class serial debugging software, select the baud rate of 9600, send A0 01 01A2 to open the relay in the form of hexadecimal (HEX); send A0 0100 A1 to close the relay in the form of hexadecimal (HEX), you can choose to send manually or automatically send.

Manual transmission.
Select baud rate 9600, tick ‘' HEX send ‘', enter the command A00101A2 or A0 01 00 A1, point ‘' send ‘', you can open or close the relay.

Timed transmission.
Select baud rate 9600, tick ‘' HEX SEND ‘' and ‘' TIMED SEND ‘', input command A0 0104 A5, tap ‘' SEND ‘', then you can realise timed opening or closing of the relay.

Automatic transmission.
Select baud rate 9600, click ‘'Extension‘' in SSCOM32 interface, input commands A0 0101 A2 and A0 01 00 A1, check ‘HEX Send'‘, input interval time of auto-cycle send, check “”Auto-cycle send'", then the relay can be turned on and off automatically. Communication protocol description.
