Sharp/NEC LED FE009I2-104 Control Spec

Summary

Sharp/NEC projector control spec covering RS-232C serial and TCP (wired/wireless LAN) control interfaces. Binary framed protocol with hex byte commands, checksum, control ID and model code. Covers power, input switch, mutes, picture/volume/aspect/gain adjust, shutter, lens control/memory, status queries, eco mode, edge blending, PIP/PbP, and audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; default not stated
  baud_rate_options: [4800, 9600, 19200, 38400, 115200]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not explicitly stated; full-duplex noted
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source
# Framing: commands/responses are hex byte sequences wrapped in a frame.
# Frame layout: [op1] [op2] <ID1> <ID2> [LEN] <DATA...> <CKS>
# ID1 = control ID (set on projector), ID2 = model code (varies by model).
# CKS = checksum: sum of all preceding bytes, low-order one byte.

Traits

traits:
  - powerable       # inferred from POWER ON/OFF commands (015/016)
  - routable        # inferred from INPUT SW CHANGE (018) and AUDIO SELECT SET (319-10)
  - queryable       # inferred from many *REQUEST commands
  - levelable       # inferred from PICTURE/VOLUME/ASPECT/GAIN adjust commands

Actions

# All command payloads verbatim from source. Hex byte sequences.
# <ID1>, <ID2>, <CKS> are frame parameters inserted by the transport layer.
# Format: "OP1 OP2 00 00 LEN [DATA...] <CKS>" - ID1/ID2 inserted between OP2 and LEN.

confirmation_required_for:
  - power_off_016       # source: cooling time blocks other commands
  - shutter_close_051   # lens shutter blocks projection
interlocks:
  - "POWER ON (015): no other command accepted during power-on sequence."
  - "POWER OFF (016): no other command accepted during power-off incl. cooling time."
  - "PICTURE MUTE ON (020): auto-cleared on input/video signal switch."
  - "SOUND MUTE ON (022): auto-cleared on input/video signal switch or volume adjust."

  - "Error 02h 0Fh: no authority for operation."
# UNRESOLVED: power-on sequencing voltage/current specs not in source.

Notes

• Binary framed protocol. All commands and responses are hex byte sequences. <ID1> = control ID set on projector, <ID2> = model code (model-specific), <CKS> = checksum (sum of preceding bytes, low byte).
• Command direction prefix in response: A-prefixed opcode (e.g. A2h, A3h, A0h, A1h) = error response; 2-prefixed (e.g. 22h, 23h, 20h, 21h) = success response.
• Serial config: 115200/38400/19200/9600/4800 bps selectable (default not stated), 8N1, full duplex. Cross serial cable required.
• TCP port 7142 for LAN control (wired or wireless LAN unit).
• Response error codes (ERR1/ERR2) documented in section 2.4: 00h/00h unrecognized, 00h/01h unsupported by model, 01h/00h invalid value, 02h/0Dh power off, 02h/0Eh execution failed, 02h/0Fh no authority, 03h/00h wrong gain number, etc.
• Several commands reference an appendix "Supplementary Information by Command" for value tables (input terminals, aspect, eco mode, base model type, sub input). These appendix values are not present in this refined source and are marked UNRESOLVED.
