Summary

Sharp/NEC Ld E151 F projector. Control via RS-232C serial (PC CONTROL D-SUB 9P) and TCP/IP LAN (wired RJ-45, wireless via optional LAN unit). Binary, hex-byte, checksummed command protocol described in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). 53 documented commands covering power, input switching, mute, picture/volume/aspect/gain adjust, lens control & memory, shutter, freeze, status/information queries, eco mode, PIP/PbP, edge blending, and audio select.

Notes

  • Binary, checksummed hex-byte protocol over both RS-232C and TCP/IP (LAN). Same command set on both transports.
  • RS-232C: D-SUB 9P PC CONTROL port, cross cable. Pins 2/3 = RxD/TxD, 5 = GND, 7/8 = RTS/CTS. Full duplex, 8N1, baud 4800/9600/19200/38400/115200.
  • TCP: port 7142 (stated). Wired 10/100BASE-TX auto-negotiate, or wireless via optional LAN unit.
  • Checksum (CKS): low-order byte of the sum of all preceding bytes. Worked example: 20h 81h 01h 60h 01h 00h -> 103h -> CKS=03h.
  • Responses: success frame lead byte = command lead + 20h; error frame lead byte = command lead + A0h, carrying ERR1/ERR2.
  • Error codes (ERR1/ERR2) include: unrecognized command (00/00), not supported by model (00/01), invalid value (01/00), invalid input terminal (01/01), power off (02/0Dh), execution failed (02/0Eh), no authority (02/0Fh), no signal (02/07h), memory in use (02/02h), forced onscreen mute on (02/04h), incorrect gain number (03/00), adjustment failed (03/02). Full list in §2.4.
  • Lamp/filter usage time reported in seconds; updated at 1-minute intervals. Lamp remaining life (%) goes negative if replacement deadline exceeded.

Spec done. 53 actions enumerated, all hex payloads verbatim. UNRESOLVED markers kept for appendix-deferred value sets, default baud, flow control, ID1/ID2, firmware.
