Summary

RS-232 control spec for Iiyama TE7568MIS interactive intelligent panel (LED LCD). Covers power, source select, volume/mute, aspect ratio, and remote-control key forwarding. Transport is serial, 9600 8N1, no flow control. Frame format: AA BB CC <Main> <Sub> <Len=00> <Checksum> DD EE FF where checksum = sum of bytes 4–6.

Transport

protocols:

Notes

Source uses DB9 pinout: Pin2=TXD, Pin3=RXD (pin-to-pin / null-modem crossover). All commands share the 10-byte frame AA BB CC <Main> <Sub> 00 <Checksum> DD EE FF. Checksum is the low byte of (Main + Sub + Length); for fixed Sub/Length=0x00 commands, checksum is just Main. TV Channel example (XX=0-99, **=XX+05) appears in source but no corresponding TV-channel command table — not emitted as an action.
