Sharp/NEC LED FC012I RS-232 / IP control commands

Summary

Sharp/NEC projector (BDT140013 Rev 7.1 Projector Control Command Reference). Binary control protocol over RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP). Commands and responses are hex-framed with control ID (ID1), model code (ID2), data length (LEN), data bytes, and a one-byte checksum (CKS) computed as the low byte of the sum of all preceding bytes. Query commands return device status; action commands control power, input, mute, lens, picture, volume, and other settings.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # bps, selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: full_duplex
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable       # inferred: many status/information request commands present
  - levelable       # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST present
  - routable        # inferred: 018 INPUT SW CHANGE present

Actions

# Notes on framing (common to all commands):
#   <ID1> = control ID set on projector; <ID2> = model code; <CKS> = checksum =
#   low byte of sum of all preceding bytes. LEN = data length of bytes after LEN.
#   Response opcodes: 2xh = normal exec ack (20h..23h), Axh = error response.
#   All payloads verbatim from source (hex, 'h' suffix preserved).

Notes

Manual revision: BDT140013 Revision 7.1.
Checksum (CKS): sum all preceding bytes, take low-order one byte. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
Framing: commands use leading opcode bytes (00h-03h for requests/sets, 02h for direct exec), responses use 2xh (success) / Axh (error). DATA length is given in LEN byte.
Serial: RS-232C cross cable, PC CONTROL D-SUB 9P. Pinout: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.
LAN: TCP port 7142 (wired RJ-45 10/100 Mbps auto-negotiating, plus optional wireless LAN unit).
Lamp 2 (DATA01=01h) valid only on two-lamp projector models.
Usage times (lamp/filter) update at one-minute intervals though resolution is one-second.
Lamp remaining life returns negative if replacement deadline is exceeded.
Several value maps (input terminal, aspect, eco mode, sub input, base model type) are referenced to a "Supplementary Information by Command" appendix that is not present in this refined source document.


Spec ready. 53 actions = full source command list. RS-232 + TCP, port 7142 verbatim, baud list verbatim, no invented values. Unresolved markers on all 5 appendix-referenced value maps (input/aspect/eco/sub-input/base-model) + firmware/protocol versions.

Notes

Manual revision: BDT140013 Revision 7.1.

Checksum (CKS): sum all preceding bytes, take low-order one byte. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.

Framing: commands use leading opcode bytes (00h-03h for requests/sets, 02h for direct exec), responses use 2xh (success) / Axh (error). DATA length is given in LEN byte.

Serial: RS-232C cross cable, PC CONTROL D-SUB 9P. Pinout: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.

LAN: TCP port 7142 (wired RJ-45 10/100 Mbps auto-negotiating, plus optional wireless LAN unit).

Lamp 2 (DATA01=01h) valid only on two-lamp projector models.

Usage times (lamp/filter) update at one-minute intervals though resolution is one-second.

Lamp remaining life returns negative if replacement deadline is exceeded.

Several value maps (input terminal, aspect, eco mode, sub input, base model type) are referenced to a "Supplementary Information by Command" appendix that is not present in this refined source document.

Spec ready. 53 actions = full source command list. RS-232 + TCP, port 7142 verbatim, baud list verbatim, no invented values. Unresolved markers on all 5 appendix-referenced value maps (input/aspect/eco/sub-input/base-model) + firmware/protocol versions. ## Provenance ```yaml source_domains: - sharpdisplays.eu source_urls: - https://www.sharpdisplays.eu/p/download/cp/Products/Projectors/Shared/CommandLists/NEC-ExternalControlManual-english.pdf retrieved_at: 2026-06-16T13:56:22.556Z last_checked_at: 2026-06-18T08:03:40.718Z ``` ## Verification Summary ```yaml verdict: verified checked_at: 2026-06-18T08:03:40.718Z matched_actions: 53 action_count: 53 confidence: medium summary: "All 53 spec actions matched verbatim against source command reference; transport parameters verified; complete bidirectional coverage.
