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 sending00h;01h/02h/03handFFh/FEh/FDhare 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.
Spec above. 53 actions, one per source command row, payloads verbatim. All YAML fences comment-free per format constraint; inferences moved to HTML comments outside fences. No port/baud/flow-control invented — flow_control left null.

```yaml
- "specific model-code (ID2) value for this projector not stated in source; varies by model."
- "control ID (ID1) configurable value not stated; must match projector setting."
- "firmware version compatibility not stated in source."
- "input terminal hex codes (DATA01 of command 018 and others) deferred to \"Supplementary Information by Command\" appendix, which is not present in the refined source."
- "eco_mode_value enum values deferred to source appendix not present in refined doc."
- "source documents no unsolicited notifications; device responds only to commands."
- "no multi-step sequences described in source."
- "source notes power on/off and cooling periods reject other commands, but states no explicit safety interlock procedures. No voltage/current/power specs present in source."
- "input-terminal / sub-input / aspect / eco-mode hex code tables live in source appendix \"Supplementary Information by Command\", not included in the refined document."
- "model code (ID2) for V864Q Avt3 not stated."
- "default baud rate among the five supported not stated."
- "wireless LAN unit models and wireless port details not in source."
