Summary

Sharp/NEC projector (BDT140013 Rev 7.1 command reference) controllable via RS-232C serial and TCP/IP (wired/wireless LAN, TCP port 7142). Spec covers the binary hex command set: power, input switching, mutes, picture/volume/aspect/gain adjust, lens control & memory, status queries, eco mode, PIP/PbP, edge blending, and audio select.

# UNRESOLVED: no explicit power-on sequencing requirement stated; only command-acceptance interlocks derived

Notes

  • Commands and responses use binary hex frames: 20h 88h <ID1> <ID2> 0Ch <DATA01>-<DATA12> <CKS>. <ID1> is the configured control ID; <ID2> is model code (varies by model).
  • Checksum <CKS> = low-order byte (8 bits) of the sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Response framing prefix: A0h/A1h/A2h/A3h indicate error response category paired with the command opcode; 20h/21h/22h/23h are normal responses.
  • Lamp usage time and filter usage time returned in seconds; updated by projector at 1-minute intervals.
  • Lamp remaining life (%) returned negative once replacement deadline exceeded.
  • Lens +/-continuous (7Fh/81h) drive requires explicit Stop (00h) afterwards.
  • Error code table (ERR1/ERR2) covers 25 distinct error combinations (unrecognized cmd, unsupported, invalid value, invalid input, invalid language, memory errors, forced onscreen mute, no signal, power off rejection, no authority, gain errors, adjustment failed, etc.).
  • Source doc says "projector" throughout (BDT140013 Rev 7.1). LED E025I 217In model name supplied externally.

Spec generated. 53 actions covering all commands in source BDT140013 Rev 7.1. Serial + TCP both populated (port 7142 stated). Major gap = "Supplementary Information by Command" appendix referenced but not in refined source.

Known Gaps

- "device name in source doc only says \"projector\"; \"LED E025I 217In\" supplied by operator, not corroborated inside the source text"
- "input terminal value table referenced as \"Supplementary Information by Command\" appendix not present in refined source"
- "ID2 model code value not stated in source (varies by model)"
- "source states \"Full duplex\" communication mode but no explicit flow-control line"
- "appendix values not present in source\""
- "appendix values not present in source"
- "no unsolicited notification mechanism described in source - all responses are command echoes"
- "no multi-step sequences explicitly described in source"
- "no explicit power-on sequencing requirement stated; only command-acceptance interlocks derived"
- "input-terminal value table (DATA01 for 018/319-10) lives in \"Supplementary Information by Command\" appendix not included in refined source"
- "aspect value table lives in same appendix — not present"
- "eco mode value table lives in same appendix — not present"
- "ID2 model code for this specific model not stated"
- "firmware version compatibility not stated in source"
- "voltage / current / power specs not in this command reference (likely in operation manual)"
