Summary

Control spec derived from the Sharp/NEC "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). The device exposes a binary, hex-framed control protocol over both RS-232C serial and TCP/IP (LAN). Commands cover power, input switching, mute (picture/sound/onscreen), picture/volume/aspect/lamp adjustment, lens control and memory, status queries, eco mode, PIP/PbP, edge blending, and audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # UNRESOLVED: source lists 115200/38400/19200/9600/4800 bps; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Full duplex" communication mode and wires RTS/CTS pins, but does not name a flow-control setting
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF commands present
  - routable     # inferred: 018 INPUT SW CHANGE command present
  - queryable    # inferred: many status request commands present (037/053-1/060-1/078-*/084/097-*/305-*)
  - levelable    # inferred: 030-1 PICTURE / 030-2 VOLUME / 030-15 LAMP adjust commands present

Actions

# All 53 command rows from source §2 enumerated. Hex payloads verbatim.
# ID1 = control ID, ID2 = model code, CKS = checksum (low byte of sum of preceding bytes).
# ID1/ID2 values not stated in source → UNRESOLVED; CKS is computed per-source rule.

Events

# UNRESOLVED: source describes only command/response model; no unsolicited
# notification events documented.

Macros

# UNRESOLVED: source documents no explicit multi-step sequences.

Safety

confirmation_required_for: []
interlocks:
  - command: cmd_015_power_on
    rule: "No other command accepted while power-on in progress."
  - command: cmd_016_power_off
    rule: "No other command accepted during power-off including cooling time."
  - command: cmd_053_lens_control
    rule: "After continuous-drive (7Fh/81h), must send 00h to stop."
# UNRESOLVED: no voltage/current/power specs, no power-on sequencing procedure
# beyond the per-command interlock notes above.

Notes

  • Checksum (CKS): low-order byte of the sum of all preceding bytes. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Command frames begin with a 2-byte header where byte0 indicates command class (00h/01h/02h/03h) and byte1 is the opcode; responses prefix byte0 with A (e.g. 02h→A2h, 03h→A3h) on error, or 2x on success.
  • Error responses carry ERR1/ERR2 code pairs (see source §2.4, 20+ combinations); examples: 02h 0Dh = "command cannot be accepted because the power is off", 00h 01h = "command not supported by model".
  • Lamp/filter usage time returned in seconds, updated at 1-minute intervals.
  • ID1 (control ID) and ID2 (model code) values are device-specific and not stated in this source text.

summary: "All 53 spec commands matched verbatim hex sequences in source. Transport parameters verified. One-to-one coverage. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "The supplied device name \"Ea231Wu Bk\" is a Sharp/NEC monitor model, but the source document is a generic *projector* control command reference (references lamp, lens, shutter, lamp memory). The source does not state a specific model name. Model-to-source compatibility is unconfirmed."
- "Default baud rate not stated (source lists 5 options); model code (ID2) value not stated; input terminal value table lives in an appendix not included in the source text."
- "source lists 115200/38400/19200/9600/4800 bps; default not stated"
- "source states \"Full duplex\" communication mode and wires RTS/CTS pins, but does not name a flow-control setting"
- "appendix not in source text.\""
- "value table in source appendix not included in source text\""
- "not in source text\""
- "source describes only command/response model; no unsolicited"
- "source documents no explicit multi-step sequences."
- "no voltage/current/power specs, no power-on sequencing procedure"
- "appendix \"Supplementary Information by Command\" (input terminal codes, aspect values, eco mode values, base model type values, sub-input values) is referenced but not present in the provided source text."
- "device-name vs source mismatch (monitor name supplied, projector manual provided) — verify correct source artifact before publishing."
