Summary
Sharp/NEC display controlled via the vendor "Projector Control Command Reference Manual" (BDT140013 Revision 7.1), a binary hex-frame protocol carried over RS-232C serial and/or TCP LAN (port 7142). The spec enumerates all 53 documented commands: power, input switching, mute, picture/volume/aspect/lamp adjust, lens control and memory, shutter, freeze, status/information queries, eco mode, PIP/PbyP, edge blending, and audio select.

This is a generic projector command reference; model-specific command support (ID2 model code) is defined in an "Appendix / Supplementary Information by Command" not present in the provided source text.
- Checksum (CKS): low-order byte of the sum of all preceding bytes in the frame (source §2.2). For fixed commands the literal checksum is shown; for parameterized commands
{cks}must be computed. - Frame header conventions observed: command frames begin 00h-03h; success responses begin 20h/21h/22h/23h; error responses begin A0h/A1h/A2h/A3h.
- Error responses carry ERR1/ERR2 code pairs (source §2.4 lists 24 combinations, e.g. 00h/00h = command not recognized, 01h/00h = invalid value, 02h/0Eh = execution failed).
- Serial connection uses a cross (null-modem) cable on the PC CONTROL D-SUB 9P port; LAN connection uses RJ-45 (wired) or an optional wireless LAN unit.
- Many enum value lists (input terminal, aspect, eco mode, sub input, base model type) are deferred to the source Appendix which is not included here.

Known Gaps
- "source is a generic projector command reference (lens, lamp, shutter, filter commands) whose model-specific applicability to the C651Q Avt2 display is not confirmed in the document. Model code (ID2) and command support per model live in an \"Appendix / Supplementary Information by Command\" not included in the source text."
- "flow control not stated in source (RTS/CTS pins present but setting not documented)"
- "source does not describe any push/event mechanism."
- "no macros documented."
- "source contains no explicit safety warnings or power-on sequencing procedures"
- "model-specific command applicability and ID2 model code for C651Q Avt2 not in source text."
- "serial flow_control setting not stated."
- "input terminal / aspect / eco mode / sub input enum value lists not in provided source (in Appendix)."
