Summary

Sharp/NEC LED projector with binary RS-232C and TCP/IP control interface. Spec covers power, input switching, mute, picture/volume/lens adjustment, lens memory, eco mode, edge blending, PIP/PbP, and status queries per BDT140013 Rev 7.1. Command frame format: hex bytes with trailing checksum byte.

Notes

  • BDT140013 Revision 7.1 command reference. Binary protocol: each command/response is a frame of hex bytes terminated by a checksum byte (CKS).
  • Checksum = low-order byte of sum of all preceding bytes (source §2.2 worked example).
  • Command frames use 00h 00h for ID1/ID2 placeholders in source examples; runtime must substitute the projector's actual control ID and model code.
  • Response result-byte prefix encodes success vs error: 20h/21h/22h/23h = success (echoes command-group byte), A0h/A1h/A2h/A3h = error (carries ERR1/ERR2).
  • Lamp/filter usage times returned in seconds but updated at one-minute intervals.
  • Lamp remaining life (%) returned as negative value once replacement deadline exceeded.
  • 020–025 mute commands auto-clear on input/video-signal switch (and volume adjust for sound mute).
  • Source repeatedly references an Appendix "Supplementary Information by Command" not included in the refined document — input terminal codes, aspect values, eco mode values, base model types, selection signal types, and sub-input values live there.

Spec built. 53 actions enumerated (one per source command row). Binary payloads verbatim. 4 queries promoted to Feedbacks (power, error, command result, lens state). Multi-value commands kept as single parameterized actions per granularity rule.

Gaps flagged UNRESOLVED: model code (ID2), Appendix enum tables, lens target codes beyond 06h, firmware compat.
