Summary

Sharp/NEC LED FC012I 110IN is a large-format LED projector controllable over RS-232C serial and TCP/IP LAN. This spec covers the binary command protocol documented in the vendor Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input, mute, lens, picture/volume, information queries, and edge-blend / PiP / PaP settings.

Transport

protocols:
  - serial
  - tcp
# Serial: RS-232C, D-SUB 9P cross cable, full duplex.
# TCP: port 7142 (both directions), wired/wireless LAN.
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; RTS/CTS wired on D-SUB per pin table
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: POWER ON (015) / POWER OFF (016)
  - queryable      # inferred: many status/information request commands
  - routable       # inferred: INPUT SW CHANGE (018), audio select (319-10)
  - levelable      # inferred: picture/volume/lens adjustments
  - muteable       # inferred: picture/sound/onscreen/shutter mute commands

Actions

# Frame format (all commands): {HEADER} {ID1} {ID2} {LEN} {DATA...} {CKS}
#   ID1  = control ID set on projector
#   ID2  = model code (model-dependent)
#   LEN  = byte length of DATA part following LEN
#   CKS  = checksum = low byte of sum of all preceding bytes
# The command templates below show the fixed header/LEN bytes verbatim and the
# variable DATA bytes as placeholders. ID1/ID2/CKS are runtime-computed.

Notes

  • Source: Projector Control Command Reference Manual, BDT140013 Rev 7.1.
  • Protocol is binary; all bytes shown as NNh (hex). Frame = {HEADER} {ID1} {ID2} {LEN} {DATA...} {CKS}.
  • Checksum: low-order byte of the sum of all preceding bytes. Worked example in source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • ID1 (control ID) and ID2 (model code) are per-device values not specified in source — runtime parameters.
  • Response ACK header uses Axh prefix mirroring the command's 0xh (e.g. 02h→22h success / A2h error).
  • Error responses carry <ERR1> <ERR2> per the §2.4 error-code table (24 codes documented).
  • Lamp/filter usage times returned in seconds, updated at one-minute granularity.
  • Source references an "Appendix: Supplementary Information by Command" containing the full input-terminal, aspect, eco-mode, and base-model-type value tables. That appendix is NOT in the refined source — several params above are marked UNRESOLVED pending it.

Spec built. 51 actions (one per documented command opcode). Serial + TCP transport. All hex payloads verbatim. UNRESOLVED markers for appendix-dependent value tables + firmware. Ready for ingest.

- "exact value map not in refined source"
- "source documents no unsolicited notifications. All responses are"
- "no multi-step sequences described in source."
- "power-on sequencing, voltage/current specs, and fault-recovery"
- "firmware version compatibility not stated in source"
- "input-terminal value table (018, 319-10) not in refined source"
- "aspect value table (030-12) not in refined source"
- "eco-mode value table (097-8, 098-8) not in refined source"
