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

protocols:

  parity: odd
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source
  connector: D-Sub 9-pin male (EXTERNAL CONTROL)
  cable: crossed (reverse) cable
  communication_code: hex

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.
