Notes

Command packet structure:

Byte 0: STX = 0x07
Byte 1: IDT = 0x00 (Monitor ID; can be 0x00–0x0F)
Byte 2: Type = 0x01 (read), 0x02 (write), 0x00 (response from monitor)
Byte 3-5: CMD (3 ASCII bytes)
Byte 6: [Value] (write commands only)
Byte 7: ETX = 0x08

Response format: Monitor echoes CMD in response bytes 3–5. Type byte always 0x00 in monitor→PC direction.

Wake-on-Sleep note: ▲ symbol indicates command valid in power-saving/off mode only when Wake Up From Sleep is set to "VGA, Digital, RS232" (WFS=1).

Serial port default: 19200 8N1. Baud rate adjustable via BRA command to 115200/38400/19200/9600.

Video wall matrix encoding: X value in high nibble (bits 7–4), Y value in low nibble (bits 3–0).
