Samsung QM85D / LH55OMD / 75OMD Control Spec

Summary

Samsung LFD (Large Format Display) signage control via Samsung's MDC (Multiple Display Control) protocol. The protocol runs over RS-232 (DB9, 9600/8/N/1) and over TCP/IP (default 192.168.0.10, port 1515), carrying identical payload framing. Each command begins with header 0xAA, command byte, ID, data length, data bytes, and a single-byte checksum (sum of preceding bytes, truncated to a byte).

Traits

- powerable       # inferred from 0x11 Power Control examples
- routable        # inferred from 0x14 Input Source Control examples

Actions

# All commands share framing: 0xAA <cmd> <id> <data_len> <data...> <checksum>
# For SET commands, append the literal payload field shown for each action.
# For GET commands, omit the data field and append a checksum over the request.

Notes

• Default TCP target: 192.168.0.10 port 1515. For power-on via RJ45 with Network Standby OFF (DMD/DBD/DHD/UED/DMD-S), use WOL instead of MDC; otherwise MDC is fine.
• RJ45 set + serial coexistence: if 0x1D=0x01 (RJ45), serial MDC stops working.
• Power commands over RJ45 require socket re-connect after ~10s and retry up to 3x every 2s waiting for ACK.
• RS-232: 3-wire (RxD/TxD/GND), max distance 4m, ID 0..253 (0xFE = broadcast).
• Checksum = sum of all preceding bytes (header through last data byte), truncated to one byte. Source example: 11+FE+01+01=111 → discard high digit → 0x11.
• Document scope: covers Samsung Multiple Display Control protocol as used by QM-series (model 0x52) and OMD/LH-OMD series (model 0x4A/0x50). Many commands are model-conditional; the spec lists every command-bearing row the source enumerates, with command: field carrying the literal byte sequence so implementations can drive both transports.
