Summary

Sharp/NEC LED projector. Control via RS-232C (PC CONTROL D-SUB 9P) and/or wired/wireless LAN (TCP port 7142). Spec covers full binary command catalogue from BDT140013 Rev 7.1 — power, mute, input switch, picture/volume/aspect adjust, lens control + memory, information/status queries, eco/PIP/edge-blend set, audio select.

Variables

# Settable parameters handled via Actions (picture/volume/aspect/lamp/eco/PIP/edge-blend/lens-memory-option).
# No additional standalone variables documented beyond those actions.

Events

# UNRESOLVED: source documents no unsolicited notifications. Device is poll-only.

Macros

# UNRESOLVED: source documents no multi-step command sequences.

Safety

Notes

  • Binary protocol. Framed commands carry <ID1> (control ID) + <ID2> (model code) after the command byte; CKS = low byte of sum of all preceding bytes. Checksum must be computed by implementer — not pre-baked except where source prints full example.
  • Baud options: 115200 / 38400 / 19200 / 9600 / 4800. Default UNRESOLVED — picked 9600 placeholder; verify on device.
  • TCP port 7142 (stated). Wireless LAN unit specs external to this manual.
  • Several DATA values reference appendix "Supplementary Information by Command" not present in refined source — input terminal list, aspect values, eco-mode values, sub-input values, base-model-type values all UNRESOLVED for their full enum.
  • Lamp remaining life (%) returns negative if replacement deadline exceeded.
  • Usage times update at 1-minute intervals though stored in 1-second units.

Spec done. 53 actions, all commands from source enumerated verbatim. Transport dual serial+tcp, port 7142 stated, baud options listed default marked UNRESOLVED. Appendix enum tables flagged UNRESOLVED (not in refined source).
