Summary

Sharp/NEC NP P452W projector control spec per "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). Device supports RS-232C serial control and wired/wireless LAN control over TCP port 7142. Binary command protocol using hex byte frames with ID1 (control ID), ID2 (model code), and checksum bytes. Covers power, input switch, mute, picture/volume/aspect adjust, lens control & memory, status queries, eco mode, edge blending, PIP/PbP, and audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists selectable: 115200/38400/19200/9600/4800
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow_control
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable     # inferred from POWER ON / POWER OFF commands
  - routable      # inferred from INPUT SW CHANGE command
  - queryable     # inferred from many REQUEST/query commands
  - levelable     # inferred from PICTURE ADJUST / VOLUME ADJUST commands

Actions

# All command frames verbatim from source. ID1, ID2, CKS are runtime-computed
# (ID1 = control ID set on projector; ID2 = model code; CKS = low byte of sum
# of all preceding bytes per section 2.2). Commands shown WITHOUT leading
# 20h/22h/A2h frame markers where source lists the bare opcode row; full
# request frames shown as documented.

Events

# UNRESOLVED: source documents no unsolicited notifications; device responds
# only to commands. No event/subscription mechanism described.

Macros

# UNRESOLVED: source documents no explicit multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements beyond notes that no other command is
# accepted during power on/off transitions.

Notes

  • Command frames use hex notation with h suffix. Each full frame includes leading header byte (20h/02h/03h/01h/00h for requests, 22h/23h/21h/20h for success responses, A2h/A3h/A1h/A0h for error responses) followed by opcode, <ID1> (control ID), <ID2> (model code), length, data, and <CKS> (checksum).
  • Checksum (CKS) = low-order byte of sum of all preceding bytes.
  • Power ON/OFF commands lock out all other commands during transition (incl. cooling).
  • Picture/Sound/Onscreen mute auto-clear on input/video switch; Sound mute also clears on volume adjust.
  • Lamp/filter usage time reported in seconds, updated at 1-minute intervals.
  • Lamp remaining life (%) returned negative if replacement deadline exceeded.
  • Error response format: A2h <opcode> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>. Full ERR1/ERR2 code table in section 2.4 (24 distinct error codes).
  • Remote key code 050 command emulates IR remote; full 25-key code list included in source.
