Summary

Sharp/NEC projector (LD FE193) controlled via RS-232C serial or wired/wireless LAN (TCP port 7142). Binary hex command protocol with leading-byte + trailing checksum framing. Spec covers the full BDT140013 Rev 7.1 command catalogue: power, input select, mute, picture/volume/aspect adjust, lens control & memory, status/usage queries, eco/PIP/edge-blend/audio settings.

Notes

  • Binary hex framing. Format: <lead> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. Lead bytes: 00h/01h/02h/03h command, 20h/21h/22h/23h reply (success), A0h–A3h reply (error).
  • Checksum = low-order byte of sum of all preceding bytes.
  • ID1 = projector control ID; ID2 = model code (varies per model).
  • Multiple baud rates supported (115200/38400/19200/9600/4800); default not stated.
  • Several commands reference an "Appendix: Supplementary Information by Command" for input-terminal / eco-mode / sub-input value enums — that appendix is not present in this source document.

Known Gaps

- "source does not state device-specific input terminal value table (cross-references an \"Appendix\" not included). Many DATA enums reference appendix values not present in this document."
- "enum not in source). Example 06h = video port.\""
- "enum not in source)\""
- "sub-input enum not in source)\""
- "source describes no unsolicited notifications; responses are request/reply only."
- "source documents no explicit multi-step sequences."
- "source lists no power-on sequencing procedure or external interlock wiring requirements."
- "model name \"LD FE193\" taken from user-supplied device name; source doc is a generic \"Projector Control Command Reference Manual\" (BDT140013 Rev 7.1) and does not name the model."
- "firmware version not stated."
- "default baud rate not stated; 9600 chosen as conservative placeholder — confirm against device menu."
- "ID2 model-code value not in source."
- "Appendix enums for input terminal, eco mode, PIP sub-input not included in source."
