Summary

Professional LCD projector (Sharp/NEC V864Q Avt3) controlled via binary hex frames over RS-232C serial (D-SUB 9P PC CONTROL port) or wired/wireless LAN (TCP). Covers power, input switching, mutes, picture/volume/aspect/gain adjustment, shutter, lens control and memory, status/error/lamp/filter queries, eco mode, PIP/PbP, edge blending, and audio select. Command reference BDT140013 Rev 7.1.

Notes

  • Commands and responses are binary hex frames. Each frame begins with a header byte (00h-03h command direction, 20h/21h/22h/23h/A0h-A3h response direction) and ends with <CKS> checksum.
  • Checksum (CKS): low-order one byte of the sum of all preceding bytes. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • ID1 = control ID set on projector; ID2 = model code (varies by model). Both appear in every response frame.
  • LEN = byte length of the DATA part following LEN.
  • During POWER ON/OFF (incl. cooling) the projector accepts no other command.
  • LENS CONTROL plus/minus drive (7Fh/81h) must be stopped by sending 00h; 01h/02h/03h and FFh/FEh/FDh are timed (1s/0.5s/0.25s) and self-stop.
  • Signal list numbers returned by INPUT STATUS REQUEST are 1 less than the practical value (add 1).
  • Lamp/filter usage times are returned in seconds, updated at one-minute intervals.
  • Response error format: Axh <opcode> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>. Full ERR1/ERR2 table in source §2.4.
