Summary

Sharp/NEC projector (Ld Fe153) control spec covering the binary command protocol documented in the "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). Supports RS-232C serial and TCP (wired/wireless LAN) transports. Commands are hexadecimal framed packets with a trailing additive checksum byte.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 bps as selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow_control not stated; RTS/CTS pins wired (full-duplex comm mode)
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable       (015 POWER ON / 016 POWER OFF)
# - queryable       (numerous status requests: 009, 037*, 060-1, 078*, 084, 097*, 305*)
# - routable        (018 INPUT SW CHANGE)
# - levelable       (030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 053 LENS CONTROL)
traits:
  - powerable  # inferred from power command examples
  - queryable  # inferred from query command examples
  - routable   # inferred from routing command examples
  - levelable  # inferred from volume/adjust command examples

Notes

  • Checksum (CKS): sum all preceding bytes, take low-order one byte of result (source §2.2). Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Command frame format: 20h/22h/23h/02h/03h/01h/00h <ID1> <ID2> LEN <DATA..> <CKS>. First byte encodes message class (request/ack/error). ID1 = control ID set on projector; ID2 = model code (varies by model).
  • Error responses use A0h/A1h/A2h/A3h prefix with <ERR1> <ERR2> per source §2.4 error code list (e.g. 02h 0Dh = command rejected because power is off).
  • Usage-time queries (lamp/filter) update only at one-minute intervals though stored in one-second units.
  • Serial: cross cable required; PC CONTROL port D-SUB 9P (pins 2/3 RXD/TXD, 5 GND, 7/8 RTS/CTS).
  • LAN: wired RJ-45 (10/100 auto) or optional wireless LAN unit; both use TCP port 7142.

Spec done. 53 actions, all hex payloads verbatim from source. Ports/serial/transport = direct from source. Auth none = Tier 2 inference. Gaps marked UNRESOLVED (model name in-doc, firmware, eco-mode enum, appendix-referenced tables, flow_control).
