Summary
The Sharp/NEC Xp X141Q B is a projector controllable via RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP). This spec covers the binary command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mute, picture/volume/aspect adjust, lens control & memory, status queries, and LAN settings commands. Commands are framed hex bytes with an additive low-byte checksum; responses echo the command with status/error bytes.

confirmation_required_for: []
interlocks:
- "POWER ON (015): no other command accepted while power-on in progress"
- "POWER OFF (016): no other command accepted during power-off incl. cooling time"
- "Error code 02h 0Dh: command rejected when power is off"
- "Error code 02h 0Fh: insufficient authority for operation"
# UNRESOLVED: full power-on sequencing / interlock procedures beyond above not detailed in source
Notes
- Frame format: header bytes +
<ID1> <ID2>(control ID, model code) + LEN + DATA + checksum. Response prefix2xh(ack) orAxh(error) mirroring command opcode. - Checksum = low-order byte of sum of all preceding bytes (see §2.2 example).
ID2(model code) is model-dependent and not stated for this model in source — must be read from device or a model table.- Baud rate selectable among 4800/9600/19200/38400/115200; no single factory default stated.
- Several commands reference an "Appendix: Supplementary Information by Command" for value maps (input terminals, aspect values, eco-mode values, base model types, selection signal types) — that appendix is not in the refined source, so those enums are UNRESOLVED.
- Pin assignments: PC CONTROL D-SUB 9P (2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS); LAN RJ-45.
Spec done. 53 commands enumerated verbatim from source. Serial + TCP both in transport (port 7142 + RS-232C config). UNRESOLVED markers where appendix value maps / ID2 / default baud missing.
