Summary

The Marantz PD6140D is a plasma monitor controllable via the EXTERNAL CONTROL connector (D-Sub 9-pin male, RS-232C). This spec covers power, input selection, audio mute, picture mode, screen (aspect) mode, auto picture, and cinema mode commands documented in the vendor external control code reference.

Transport

Traits

traits:
  - powerable   # inferred: power on/off commands present
  - routable    # inferred: input selection commands present

Actions

# Note: payloads are hex bytes space-separated. Source writes them with an "H"
# suffix (e.g. 9FH 80H 60H 4EH 00H CDH); the H is hex notation and stripped here.
# Source OCR renders the Picture Mode parameter byte as "OAH" (capital O); this is
# a zero/digit OCR error - written here as 0A (valid hex for the picture-mode group).
# Each row below corresponds to one row in the source External Control Codes table.

Feedbacks

# UNRESOLVED: source documents no query/response or unsolicited feedback codes.
# The note "Contact your local dealer for a full list" implies additional codes
# may exist but none are specified here.

Variables

# UNRESOLVED: no settable continuous parameters (volume, brightness, etc.)
# documented in source.

Events

# UNRESOLVED: no unsolicited notification codes documented in source.

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements. Power on/off are direct commands with no
# documented cooldown or warm-up interlock.

Notes

  • Source is an RS-232C external control reference for the PD6140D plasma monitor. The source explicitly states the documented codes are a subset ("Contact your local dealer for a full list of the External Control Codes if needed"), so this spec is incomplete by design.
  • Communication parameters stated verbatim: asynchronous, RS-232C, 9600 bps, 8 data bits, odd parity, 1 stop bit, hex communication code.
  • Connector is D-Sub 9-pin male labelled EXTERNAL CONTROL. Pinout documented in source: pin 2 RXD, pin 3 TXD, pin 5 GND, plus DTR/DSR/RTS/CTS handshake pins (1 and 9 No Connection). Source mandates a crossed (reverse) cable.
  • All command payloads are 6–9 hex bytes; the final byte of each command is a per-command value (appears to be a fixed checksum/sequence byte per row, not a documented algorithm — left verbatim, do not recompute).
  • Source OCR writes the Picture Mode parameter byte as "OAH" (capital O). This is a zero/digit OCR artefact; written here as 0A, the valid hex value for the picture-mode parameter group consistent with the surrounding table.
  • A separate "AUTO ID settings" feature (ON/OFF) is described in source prose but no external control hex code is given for it, so it is not enumerated as an action.

Spec done. 26 actions, one per source row. Serial transport per stated params. Marked UNRESOLVED on flow control, feedback, dealer-only full list, OCR note.
