Summary

Lexicon MC-10 surround processor (AVR class). Binary framed protocol over RS-232 (38400 8N1, null-modem) and TCP on port 50000. Every command/response frame: 21 <Zn> <Cc> <Dl> <Data...> 0D. Master zone = 0x01, Zone 2 = 0x02. Spec covers system commands 0x00–0x4F and the full RC5 IR code table dispatched via Simulate RC5 IR Command (0x08).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 50000
serial:
  baud_rate: 38400
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable      # inferred from RC5 Power On / Power Off and power-state query (Cc 0x00)
- queryable      # inferred: numerous query commands (mute, volume, source, decode mode, etc.)
- routable       # inferred: source-selection commands (Cc 0x0A video selection, Cc 0x0B audio select)
- levelable      # inferred: volume (Cc 0x0D), bass/treble/balance/sub-trim/lipsync/leveller

Actions

# Framing: 21 <Zn> <Cc> <Dl> <Data...> 0D. Zn default 01 (master) unless action targets Zone 2.
# Bytes shown space-separated as in source. RC5 actions all dispatch via Cc 0x08 (Simulate RC5).

Variables

# UNRESOLVED: settable parameters all expressed as parameterized actions above (volume, treble, bass, balance, sub trim, lipsync, leveller, cal offset, sub stereo trim, tuner preset, input name).

Events

# Unsolicited messages: per source "any change resulting from front-panel / IR inputs is relayed to the RC using the appropriate message type" - uses the same response frame format as the corresponding command.
- id: state_change_relay
  description: When state changes via front panel or IR, the unit emits the matching command's response frame unsolicited.
  format: "21 <Zn> <Cc> <Ac> <Dl> <Data...> 0D"
  source: "State changes as a result of other inputs" section

Macros

# UNRESOLVED: no multi-step macros documented in source.

Safety

confirmation_required_for:
  - factory_default_restore        # 0x05 requires 0xAA 0xAA confirmation pattern per source
  - secure_backup_save             # 0x06 requires 0x55 0x55 pattern + 4-digit PIN
  - secure_backup_restore          # 0x06 requires 0x55 0x55 pattern + 4-digit PIN
  - reboot                         # 0x26 requires literal "REBOOT" ASCII payload
interlocks: []
# UNRESOLVED: no explicit power-sequencing or interlock warnings stated. The protocol notes 0x85 ("Command invalid at this time") returned when Setup Menu open or tuner-context commands sent without tuner selected - handled by the device, no operator interlock required.

Notes

  • RS-232 wiring is null-modem (Connector1 pin 2↔Connector2 pin 3 / pin 3↔pin 2 / pin 5↔pin 5).
  • Control must be enabled before use: front-panel DIRECT button held 4s ("RS232 CONTROL ON" on VFD), or OSD → General Setup → Control → On. Default state is off for low standby power.
  • Commands 0xF0–0xFF are reserved for test functions — must not be used.
  • Response within 3 seconds; RC may send further commands before previous response received.
  • Same binary protocol over RS-232 (38400 8N1) and TCP (port 50000). AMX DDDP discovery uses ASCII AMX\r on the same TCP port.
  • RC5 system code 0x10 = master AV, 0x17 = Zone 2.
  • Spec covers the MC-10; the same protocol document describes RV-9 and RV-6 (different AMX DDDP model strings only) — out of scope for this spec.

Verification Summary

verdict: verified
checked_at: 2026-06-02T17:22:49.600Z
matched_actions: 227
action_count: 227
confidence: medium
summary: "All 227 spec actions matched verbatim in source; transport port 50000 and baud 38400 confirmed; RC5 codes, binary commands, and AMX DDDP all verified. (5 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware compatibility range, IP addressing (DHCP/static behavior), AMX DDDP exposed as `AMX\\r` text command — included as one action but framing differs from binary protocol (ASCII over the same TCP port per source)."
- "settable parameters all expressed as parameterized actions above (volume, treble, bass, balance, sub trim, lipsync, leveller, cal offset, sub stereo trim, tuner preset, input name)."
- "no multi-step macros documented in source."
- "no explicit power-sequencing or interlock warnings stated. The protocol notes 0x85 (\"Command invalid at this time\") returned when Setup Menu open or tuner-context commands sent without tuner selected - handled by the device, no operator interlock required."
- "firmware version compatibility ranges; whether port 50000 is configurable; behavior when control is disabled (presumably no response); maximum frame Data length (source says n limited to 255 for response, no command-side cap stated)."
