Summary

Sharp/NEC NP M323X projector control spec covering RS-232C serial and TCP/IP (LAN) control. The device exposes a binary command protocol with hex-framed payloads (header byte + body + checksum) documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands cover power, input switching, mute, picture/volume/aspect adjust, lens control and memory, status queries, eco mode, PIP/PbP, edge blending, and audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source supports 115200/38400/19200/9600/4800 bps; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not explicitly stated (RTS/CTS pins present on D-SUB 9P)
addressing:
  port: 7142  # TCP port stated for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable       # inferred: POWER ON / POWER OFF commands present
# - queryable       # inferred: many status/information request commands present
# - levelable       # inferred: VOLUME ADJUST / PICTURE ADJUST present
# - routable        # inferred: INPUT SW CHANGE present

Actions

# Command framing: commands are hex byte sequences. Many use header byte (02h/03h/00h/01h)
# followed by body and a trailing checksum (CKS) computed as low byte of sum of all
# preceding bytes. ID1=Control ID, ID2=Model code (projector-assigned). Parameterized
# DATA fields shown as {DATAxx}. Computed CKS shown as {CKS} where source shows <CKS>.

Variables

# Settable parameters handled as parameterized Actions (volume, picture, aspect, eco mode,
# lens position, projector name, PIP/PbP, edge blending, audio select). No additional
# standalone variables required.
# UNRESOLVED: numeric ranges for volume/picture adjust default and bounds require device query.

Events

# Source documents no unsolicited notifications. Responses are solicited only.
# UNRESOLVED: populate if device pushes async events (none described in source).

Macros

# Source documents no explicit multi-step command sequences.
# UNRESOLVED: populate if source describes macros (none present).

Safety

interlocks: []
# UNRESOLVED: source notes POWER ON/OFF lock out other commands during power transition

# explicit safety procedure or power-on sequencing requirement is documented in this excerpt.

Notes

  • Command framing is hex byte sequences with a trailing checksum (CKS) = low byte of sum of all preceding bytes. Example from source: 20h 81h 01h 60h 01h 00h → sum 103h → CKS 03h.
  • Responses use distinct header bytes by command class: A0h/A1h/A2h/A3h (error/ack) and 20h/21h/22h/23h (success with optional data). Error responses carry <ERR1> <ERR2> codes per the error code list (e.g. 02h 0Dh = "command cannot be accepted because the power is off").
  • ID1 (Control ID) and ID2 (Model code) are projector-assigned and must be obtained from the device; not stated in source.
  • Baud rate is selectable among 115200/38400/19200/9600/4800; the active value is configured on the projector. Default not stated.
  • LAN control uses TCP port 7142 for both send and receive.
  • Key code list (REMOTE KEY CODE) maps WORD key codes (e.g. 02h/00h POWER ON, 05h/00h AUTO, 84h/00h VOLUME UP) — full table in source §3.19.
