Summary

The Sharp/NEC NP P525WL is a projector controllable via RS-232C serial or TCP/IP network. This spec covers the binary command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1): power, input switching, mute, picture/volume/aspect adjust, lens control and memory, status queries, and LAN/eco/PIP/edge-blend settings.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200/38400/19200/9600/4800  # source lists all five selectable rates
  data_bits: 8
  parity: none

Traits

traits:
  - powerable   # inferred: POWER ON / POWER OFF commands present
  - queryable   # inferred: numerous REQUEST/query commands present
  - levelable   # inferred: volume, picture adjust commands present
  - routable     # inferred: INPUT SW CHANGE routing command present

Variables

# Settable parameters handled via Actions (volume, picture, eco, PIP, edge blend,
# lens memory). No additional settable scalars outside those commands.

Events

# No unsolicited notifications documented. Device is poll/response only.

Macros

# No multi-step sequences documented in source.

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON: no other command accepted while power is turning on."
  - "POWER OFF: no other command accepted while turning off (including cooling time)."
# UNRESOLVED: source describes no explicit safety interlock procedures beyond
# the power-state command-lockout notes above; no power-on sequencing rules stated.

Notes

  • Command frame format: every command/response is a hex byte series. Standard response shape uses A<major>h <minor>h <ID1> <ID2> 02h <ERR1> <ERR2> <CKS> for errors; success responses use 2<major>h/20h-prefixed frames with a LEN byte and DATA fields.
  • Checksum (CKS): sum all preceding bytes, take low-order one byte (8 bits). Worked example in source: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
  • ID1 = projector control ID; ID2 = model code (model-dependent).
  • Error codes (ERR1/ERR2) listed in source §2.4 (e.g. 00h/00h = unrecognized command, 02h/0Dh = power off, 02h/0Fh = no authority).
  • Serial: full-duplex, RS-232C, D-SUB 9P cross cable on PC CONTROL port. LAN: RJ-45, 10/100 Mbps auto, TCP port 7142.
  • While lens is driven via 053, the same command can be reissued without an explicit stop.

Spec done. 53 actions, each with verbatim hex `command:` from source. Inferred traits noted. Appendix value tables + flow_control + firmware marked UNRESOLVED (referenced but absent from refined source).

- "source describes no explicit safety interlock procedures beyond"
- "Appendix \"Supplementary Information by Command\" (referenced by 018/030-12/097-8/097-198/305-1/319-10 for input-terminal, aspect, eco-mode, sub-input, base-model-type, audio-input value tables) is not present in the refined source — those enum tables could not be populated."
