Summary

The Sharp/NEC NP-PE455WL is a projector controllable via RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN. 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/lens adjustment, lens memory, status queries, and LAN/eco/PIP/edge-blend configuration commands.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 as configurable; high value shown
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode, RTS/CTS wired on D-SUB pinout but flow_control setting not explicitly named
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON / POWER OFF commands
  - queryable    # inferred from numerous status/information request commands
  - routable     # inferred from INPUT SW CHANGE command
  - levelable    # inferred from PICTURE/VOLUME/LENS adjustment commands
  - mutable      # inferred from PICTURE/SOUND/ONSCREEN MUTE commands

Notes

  • All command/response frames use hexadecimal byte notation; checksum byte (CKS) is the low-order 8 bits of the sum of all preceding bytes. ID1 (control ID) and ID2 (model code) prefix responses.
  • Frame mnemonic prefixes: 02h/03h etc. on command requests, 2xh/3xh on success responses, Axh on error responses (e.g. A2h, A3h, A0h, A1h).
  • Serial connection uses a cross (null-modem) cable to the PC CONTROL D-SUB 9P port. RTS/CTS pins wired but explicit flow-control setting not named.
  • Baud rate is configurable across 4800 / 9600 / 19200 / 38400 / 115200 bps; data length 8 bits, parity none, stop bit 1, full duplex.
  • TCP LAN control uses port 7142 (wired 10/100BASE-T, also wireless LAN unit supported per model operation manual).
  • Several DATA enum value tables (input terminal list, base model type, eco mode values, selection signal types, aspect values) are referenced as living in a source Appendix not present in the refined excerpt; those parameter descriptions are marked accordingly.
