Introduction to Samsung MDC Protocol
Samsung's Multiple Display Control (MDC) protocol enables centralized control of Samsung commercial displays through RS-232, Ethernet, or USB connections. This protocol allows AV professionals to:
- Control multiple displays from a single source
- Automate display management tasks
- Integrate displays into larger AV control systems
- Monitor display status and health
- Schedule display operations
Key Benefits of RS-232 Control
- Reliable Communication: Dedicated physical connection ensures stable control
- Low Latency: Direct serial communication provides immediate response
- System Integration: Easy integration with control processors and automation systems
- Cost Effective: No additional network infrastructure required
- Bidirectional: Both command and status feedback capabilities
Supported Samsung Display Series
- Current Models (2020+): QM, QH, QB, DB, DM series
- Legacy Models (2015-2019): ME, MD, PM, PH, UD series
- Compatibility: Most commands work across generations with minor variations
RS-232 Setup and Wiring
Hardware Requirements
- Samsung commercial display with RS-232 port
- RS-232 cable (straight-through, not null-modem)
- Control system with RS-232 capability
- Optional: RS-232 to USB converter for PC control

Command Structure and Format
Basic Command Format
Samsung MDC commands follow this structure:
[Header][Command][ID][Data Length][Data][Checksum]Header Bytes
All commands begin with the header: 0xAA
Command Types
| Type | Description | Format |
|---|---|---|
| Set | Control command | 0xAA [CMD] [ID] [LEN] [DATA] [CHK] |
| Get | Status query | 0xAA [CMD] [ID] 0x00 [CHK] |
ID Field
- 0x00: Broadcast to all displays
- 0x01-0xFE: Specific display ID (set in display menu)
- 0xFF: Reserved
Checksum Calculation
The checksum is calculated by XORing all bytes except the header:
python
[object Object], ,[object Object],(,[object Object],):
checksum = ,[object Object],
,[object Object], byte ,[object Object], command_bytes[,[object Object],:]: ,[object Object],
checksum ^= byte
,[object Object], checksum & ,[object Object],Power Control Commands

Troubleshooting Guide
Common Connection Issues
Problem: No response from display Solutions:
- Verify cable connections (pins 2, 3, 5)
- Check communication settings (9600, 8, N, 1)
- Confirm display ID matches command
- Ensure RS-232 is enabled in display menu
Problem: Intermittent communication Solutions:
- Check cable length (max 50 feet for reliable communication)
- Use shielded cable in electrically noisy environments
- Verify proper grounding
- Check for loose connections
Problem: Commands rejected Solutions:
- Verify checksum calculation
- Ensure proper command format
- Check if display is in correct mode
- Wait for response before sending next command
Error Codes
| Error Code | Description | Solution |
|---|---|---|
0x01 | Invalid command | Check command syntax |
0x02 | Invalid ID | Verify display ID |
0x03 | Invalid data | Check data range/format |
0x04 | Checksum error | Recalculate checksum |
0x05 | Command not supported | Use alternative command |
Debug Process
- Test Basic Commands: Start with power on/off
- Verify Communication: Use status query commands
- Check Timing: Allow 100ms between commands
- Monitor Responses: Log all communication for analysis
- Isolate Issues: Test with single display first
