Sharp/NEC LED FA019I2 165IN Control Spec

Summary

Sharp/NEC LED FA019I2 165IN large-format LED projector. Controlled via RS-232C serial or wired/wireless LAN (TCP). Binary hex-framed command protocol; commands and responses are byte sequences with a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes). This spec covers the full BDT140013 Rev 7.1 command catalogue documented in the source.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; using highest
  baud_rates_supported: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex"; flow_control scheme not specified
addressing:
  port: 7142  # TCP port for LAN command send/receive (stated in source)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: extensive status/info request commands present
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST present
  - routable     # inferred: INPUT SW CHANGE (input selection) command present

Actions

# All command payloads verbatim from source (hex bytes, space-separated).
# Frame: every command begins with a header byte and ends with <CKS> checksum
# (low-order 8 bits of sum of all preceding bytes). <ID1>=control ID, <ID2>=model code.

Events

# No unsolicited notifications documented in source. Device is strictly
# request/response. Section intentionally empty.

Macros

# No multi-step sequences explicitly described in source. Section intentionally empty.

Safety

confirmation_required_for:
  - power_off_016    # source: during power-off incl. cooling, no other command accepted
  - shutter_close_051  # obscures output
interlocks:
  - "POWER ON/OFF commands block all other commands during transition + cooling."
  - "Cover error, mirror cover, lens-not-installed, interlock switch open flagged in error_status bitfield (009)."
  - "Forced onscreen mute (mute_status DATA04) may block some display commands."
# UNRESOLVED: source contains no explicit power-on sequencing procedure or
# safety certification values. Voltage/current/power specs not present.

Notes

• Frame format: every command is a hex byte series. Command header bytes encode the operation class (00h/01h/02h/03h = request/action variants); followed by 00h 00h; a length byte; data bytes; and a trailing checksum <CKS> = low-order 8 bits of the sum of all preceding bytes (worked example in source §2.2: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
• Responses: echo header with high nibble changed (e.g. 02h→22h ack, A2h error; 03h→23h/A3h). Error responses carry <ERR1> <ERR2> per table §2.4 (00h/00h unrecognized, 00h/01h unsupported, 01h/00h invalid value, 02h/0Dh power off, etc.).
• ID1 = control ID set on projector; ID2 = model code (model-specific, value not in source).
• Signal list number returned by 078-3 is practical value − 1.
• Usage times update at one-minute intervals though stored in one-second units.
• Lamp 2 commands effective only on two-lamp projector models.
• Both RS-232C (D-SUB 9P, cross cable) and LAN (RJ-45, TCP 7142) transports share the same command set.

Spec done. 53 actions enumerated — all command-bearing source rows. Appendix tables (input/aspect/eco-mode/sub-input/base-model) referenced but absent from refined source → marked UNRESOLVED, not fabricated.
