Summary

Sharp/NEC NP-PX1005QL W 18 projector control spec. Covers RS-232C serial control and wired/wireless LAN (TCP) control of power, input selection, picture/volume adjustment, lens control, lens memory, shutter, freeze, mute, eco mode, edge blending, PIP/PbP, and a broad set of status queries. Command protocol uses framed hex byte sequences with an additive low-byte checksum.

Transport

# Source documents BOTH serial (RS-232C) and LAN (TCP) connection methods.
# Both protocol groups emitted because both are explicitly described.
protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source: 115200/38400/19200/9600/4800 bps selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (RTS/CTS pins wired but mode not specified)
addressing:
  port: 7142  # TCP port for sending/receiving commands over LAN (source: section 1.2)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON / POWER OFF commands (015, 016)
  - queryable    # inferred from many status request commands
  - levelable    # inferred from picture/volume/lamp adjust commands

Actions

# Frame format (hex): bytes carry ID1 (control ID), ID2 (model code), and CKS
# (checksum = low-order byte of sum of all preceding bytes). Parameterized
# commands show {DATA??} placeholders and the trailing {CKS}.
# Response prefixes: 2xh = success ack, 3xh = success with data, Axh = error.
# Each entry below is one distinct command row from the source command list.

Notes

  • Command/response frames are hexadecimal byte sequences enclosed in a frame. Parameters appear in italics within brackets (<ID1>, <DATA01>, <CKS>).
  • Checksum (CKS): sum all preceding bytes, take the low-order one byte (8 bits) of the result. Worked example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Common parameters: ID1 = control ID set on projector; ID2 = model code (varies by model); LEN = data length of bytes following LEN; ERR1/ERR2 = response error codes.
  • Response prefixes: high nibble 2 = command succeeded with no data, 3 = succeeded with data, A = failed (carries ERR1/ERR2).
  • Baud rate is selectable among 115200/38400/19200/9600/4800 bps; the controller software must match the projector's configured rate.
  • TCP LAN control uses port 7142 (section 1.2).
  • POWER ON/OFF block all other commands while power transition is in progress (POWER OFF includes the cooling period).
  • PICTURE/SOUND/ONSCREEN mute auto-clear on input/video-signal switch; SOUND mute also auto-clears on volume adjustment.
  • Lens drive: after sending 7Fh (drive plus) or 81h (drive minus), stop by sending 00h.
  • Lamp usage/filter usage update at one-minute intervals though reported in one-second units.
  • Several value-code mappings (input terminal, eco mode, aspect, sub input for PIP/PbP, base model type) are referenced to an "Appendix / Supplementary Information by Command" not present in this refined excerpt.

Spec done. 53 commands enumerated, hex payloads verbatim, checksum noted, gaps marked.
