Summary

Sharp/NEC LED FA038I2 projector control spec. Binary frame protocol over RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP port 7142). Covers power, input switching, mutes, picture/volume/aspect adjust, lens control and memory, status queries, and PIP/PbP/edge-blend settings.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source: 115200/38400/19200/9600/4800 selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow control type

Traits

traits:
  - powerable       # POWER ON / POWER OFF
  - routable        # INPUT SW CHANGE, AUDIO SELECT SET
  - queryable       # many status/information request commands
  - levelable       # PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST, LENS CONTROL

Events

# Source documents no unsolicited notifications. All responses are to commands.

Macros

# UNRESOLVED: source documents no multi-step sequences.

Notes

  • Binary frame protocol: every command/response is a hex byte sequence ending in <CKS> checksum. Checksum = low byte of sum of all preceding bytes (see source §2.2 example).
  • Frame markers: 20h/21h/22h/23h = command/response leading bytes by command-type group; A0h/A1h/A2h/A3h = error-response leading bytes.
  • 9-pin D-SUB wired as cross cable: pin2(RxD)↔TxD, pin3(TxD)↔RxD, pin7(RTS)↔CTS, pin8(CTS)↔RTS, pin5(GND)↔GND.
  • Error code table (§2.4) covers ERR1/ERR2 combos: command unrecognized, not supported, invalid value, invalid input, invalid language, memory errors, forced mute, viewer error, no signal, test pattern shown, no PC card, memory op error, entry list shown, power-off rejection, exec failure, no authority, invalid gain, adjustment failed.
  • Information updates (lamp/filter usage, gain values) refresh at 1-minute intervals despite second-unit precision.
  • 053 LENS CONTROL: continuous drive (7Fh/81h) requires explicit 00h to stop.
  • Appendix "Supplementary Information by Command" referenced for input terminal, aspect, eco mode, sub-input, and base-model-type value enumerations — not present in refined source.

Spec done. 53 actions, all command payloads verbatim. Serial+TCP both. Appendix values marked UNRESOLVED. Ready for ingest.

Known Gaps

- "appendix \"Supplementary Information by Command\" not present in refined source — input terminal values, aspect values, eco mode values, sub-input values, base model type values referenced but not enumerated."
- "source states \"Full duplex\" communication mode but does not specify flow control type"
- "appendix not in refined source).\""
- "value list in appendix, not in refined source).\""
- "source documents no multi-step sequences."
- "firmware version compatibility not stated in source."
- "appendix value tables (input terminals, aspect, eco mode, sub-inputs, base model types) not in refined source."
- "flow_control type not stated; source only says \"Full duplex\"."
- "ID2 model code value not stated; varies by model."
