Anthem MRX SLM Control Spec

Summary

The Anthem MRX SLM is an AV receiver/processor controllable via TCP/IP on port 14999 (default) and WebSocket on port 8080. Commands are ASCII strings terminated with semicolons. The protocol supports zone power, input selection, volume, audio listening modes, speaker configuration, bass management, ARC metadata, streaming playback, and system configuration. All queryable settings that change are broadcast asynchronously to all active connections.

Transport

protocols:
  - tcp
addressing:
  port: 14999
auth:
  type: none  # inferred: no auth procedure in source

WebSocket is also available on port 8080 with identical command semantics.

Traits

traits:
  - powerable     # Z1POW power on/off commands
  - routable      # Z1INP input selection
  - queryable     # extensive query commands returning state
  - levelable     # Z1VOL, Z1PVOL, Z1TON, Z1BAL, Z1LEV volume/tone/balance/level control

Notes

• Commands use semicolon ; as the only valid separator/terminator. Query responses also terminate with semicolon.
• Successful commands return ; after execution. For immediate feedback, append the query command: e.g. Z1VOL-28;Z1VOL?;.
• Unexecutable recognized commands return !E<OriginalCommand>. Invalid commands return !I<OriginalCommand>.
• Average command processing latency is 20ms.
• Multiple commands can be combined in a single message.
• Textual data uses hex-encoded UTF-8 (2 hex chars per ASCII byte, 4-6 for multi-byte).
• If maximum connections are exceeded, the oldest connection is forcibly closed.
• WebSocket on port 8080 operates identically to the TCP socket.
• Terse volume mapping: 0%=-90dB, 4%=-74dB (step 4), 11%=-53dB (step 3), 20%=-35dB (step 2), 30%=-25dB (step 1), 100%=+10dB (step 0.5).
• Device Discovery Protocol (DDP) uses binary UDP broadcast on the local subnet with a structured packet containing device name, model, serial number, TCP port, and extended metadata.
