Sharp PN-G655U-RU Control Spec

Summary

Sharp PN-G655U-RU is a professional large-format LCD monitor controllable from a PC via RS-232C (D-sub 9 pin, straight cable). This spec covers the full RS-232C command table: power control, input selection, picture/audio/setup/option/enlarge/PIP menus, and initialization/restriction settings. The monitor supports daisy-chain connection of up to 25 units with per-monitor ID assignment and repeater control.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWR standby/return command
  - routable     # inferred: INPS input mode selection
  - queryable    # inferred: many R-direction commands (VOLM?, INPS?, etc.)
  - levelable    # inferred: VOLM, CONT, BLVL, TREBLE, BASS etc. continuous ranges

Actions

# Command format: 4-char command + 4-char parameter (padded with spaces if needed).
# Return code is 0DH, 0AH, or 0DH. Negative values in 3 digits e.g. AUTR-009.
# "?" in parameter queries current value when Direction includes R.
# Repeater control: 4th parameter character = "+" broadcasts to all daisy-chained monitors.

Events

# No unsolicited notifications documented. All responses are replies to PC-initiated commands.
# UNRESOLVED: no async event mechanism described in source.

Macros

# Repeater control pattern documented in source (broadcast a single set command to all
# daisy-chained monitors by setting 4th parameter character to "+").

- id: repeater_broadcast_example
  steps:
    - command: "VOLM030+"        # Sets volume of ALL chained monitors to 30
    - await: "WAIT"
    - collect: ["OK001", "OK002", "OK003", "OK004"]  # one OK per assigned monitor

- id: idst_auto_assign
  description: "Auto-assign sequential IDs to all chained monitors via IDST + repeater."
  steps:
    - command: "IDST001+"        # ID setting command with repeater control
    - await: "WAIT"
    - collect: ["OK001", "OK002", "OK003", "OK004"]

Safety

confirmation_required_for: []
interlocks:
  - command: POWR
    note: "Power-on commands affect display state; provide >=100ms interval after OK before next command."
  - command: INPS
    note: "Returns WAIT; do not send new command until final OK received."
temperature_monitoring:
  - query_command: "DSTA????"
    note: "Returns 0-4 temperature state. Values 1-3 indicate prior/active thermal abnormality; value 4 indicates sensor fault."
# UNRESOLVED: no explicit power-on sequencing interlock, fuse, or mains procedure stated in source.

Notes

• Command format: 4-char command field + 4-char parameter field. Parameter MUST be 4 characters — pad with spaces if needed (e.g. VOLM 30, not VOLM30). Exception: MPOS, DATE, SC01-SC08 do NOT use spaces; parameters are fixed-width per spec.
• Negative values: 3-digit signed form, e.g. AUTR-009.
• Return code terminator: 0DH, 0AH, or 0DH (per source).
• Response codes: OK (success), ERR (unknown command / unusable in current state), WAIT (processing — do not send next command), LOCKED (RS-232C operation lock active).
• ID-suffixed responses: when an ID is assigned, OK/ERR/WAIT may be followed by space + 3-digit monitor ID (e.g. OK 001). WAIT has no ID attached.
• No response scenarios: bad physical connection returns nothing; targeting a non-existent ID returns nothing.
• WAIT-producing commands: repeater control, IDSL, IDLK, RSET, INPS, ASNC, WIDE, EMAG, EPOS, PXSL, POWR, AGIN, MWIN, MWIP, MWPP, ESTG.
• Timing: command-response timeout ≥ 10 seconds; inter-command interval ≥ 100 ms after response.
• Daisy chain: up to 25 monitors, RS-232C IN→OUT straight cable. Each monitor may have an assigned ID (0-255, 0 = unassigned).
• Repeater control: 4th parameter character + broadcasts to all chained monitors. Cancels any active IDSL/IDLK designation. Cannot be used with commands whose parameter exceeds 4 characters.
• RS-232C lock: when the operation lock function is set to LOCKED, all RS-232C control is disabled and returns LOCKED.

Spec done. RS-232C-only, all source commands enumerated verbatim, gaps marked UNRESOLVED.
