Summary

Sharp/NEC ME651 PT large-format projector. Supports RS-232C serial control via the PC CONTROL (D-SUB 9P) port and TCP/IP network control via wired/wireless LAN on port 7142. This spec covers the binary command protocol (BDT140013 Rev 7.1) — power, mute, input switching, picture/volume/aspect/lens adjustment, lens memory, shutter, freeze, eco mode, edge blending, PIP/PBP, and an extensive set of status/information requests.

Notes

  • Reference manual: BDT140013 Revision 7.1. Generic NEC projector command set — applies across many models; not ME651 PT specific in framing.
  • All command/response frames are binary hex; CKS = low-order byte of sum of all preceding bytes (incl. the leading cmd byte, op, ID1, ID2, LEN, and DATA).
  • Response leading byte encodes class: 2xh success ack, Axh error ack (where x = command-group nibble matching the request).
  • Lamp/filter usage times update at 1-minute intervals despite 1-second resolution.
  • 050 REMOTE KEY CODE emulates the IR remote — useful for one-shot commands (AUTO, ASPECT, SOURCE, MENU nav) lacking dedicated opcodes.
  • ID2 (model code) byte is model-specific and not in this reference — must be obtained from the model's operation manual or discovered by sniffing an existing controller.

53 commands enumerated. Serial (multi-baud) + TCP 7142 both in source → emitted both. ID2 model code + appendix tables flagged UNRESOLVED (referenced but not in refined source).
