Summary

Binary control protocol for Sharp/NEC NP-P502WL-2 projector over RS-232C (D-SUB 9P cross cable) and wired/wireless LAN. Commands are fixed-length hex frames with a trailing checksum byte (low-order 8 bits of the sum of preceding bytes). TCP port 7142 is used for LAN transport. Covers power, input switching, mutes, picture/volume/aspect/gain adjustment, lens control and memory, information/status queries, eco mode, edge blending, PIP/PbP, and audio select.

Notes

  • All commands/responses are binary hex frames. Every frame ends in a checksum byte (CKS) computed as the low-order 8 bits of the sum of all preceding bytes. Example from source: 20h 81h 01h 60h 01h 00h sums to 103h, so CKS = 03h.
  • Frame structure: <MsgType> <Command> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1 is the configured control ID; ID2 is the model code (model-dependent). Response prefixes: 2xh = success echo of command group, Axh = error response with ERR1/ERR2.
  • Baud rate is selectable among 115200/38400/19200/9600/4800 bps — the projector and controller must be configured to match; this spec records the highest listed rate.
  • Pin assignment for the PC CONTROL port (D-SUB 9P) uses a cross/null-modem wiring: pin 2↔3 (RxD/TxD), pin 7↔8 (RTS/CTS), pin 5=GND.
  • Several commands reference an "Appendix: Supplementary Information by Command" for input-terminal codes, aspect values, eco-mode values, sub-input values, and base-model-type codes. That appendix is not present in the provided source document, so the corresponding enum ranges are marked UNRESOLVED.
  • Lamp/filter usage times are reported in one-second units but updated at one-minute intervals.

Spec ready. 53 actions, full payloads verbatim incl checksums. Both serial+TCP protocols covered (port 7142 stated). Appendix enum tables marked UNRESOLVED — not in source.
