Summary

Sharp/NEC Ld Fa192 is a projector controllable via RS-232C serial or wired/wireless LAN (TCP). This spec covers the binary hex command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mute, lens, picture/volume adjust, and status query commands. Commands are framed hex byte sequences with a trailing checksum byte.

Transport

protocols:
  - serial
  - tcp

Notes

  • Manual revision: BDT140013 Rev 7.1.
  • Commands/responses are framed hex byte sequences. Frame markers: leading byte (00h–03h for commands, 20h/21h/22h/23h for ACK responses, A0h/A1h/A2h/A3h for error responses). <ID1> = control ID set on projector; <ID2> = model code (varies by model).
  • Checksum (<CKS>): sum all preceding bytes, take low-order 8 bits. Example from source: 20h+81h+01h+60h+01h+00h = 103h → checksum 03h.
  • Error responses carry <ERR1> and <ERR2> codes per section 2.4 (e.g. 00h/00h = unrecognized command, 02h/0Dh = power off, 00h/01h = command not supported by model).
  • Lamp usage / filter usage times update at one-minute intervals despite one-second resolution.
  • Signal list number returned is (practical value − 1).
  • Several commands reference an "Appendix: Supplementary Information by Command" for input terminal, aspect, eco mode, and sub-input value tables — that appendix is not present in the refined source.

53 commands covered (22 actions + 25 feedbacks/queries + 6 dual). Binary payloads verbatim. Serial+TCP both documented. Appendix value tables marked unresolved.
