Sharp/NEC NP-PX1004UL-B Control Spec

Summary

Professional installation projector controlled via a binary RS-232C protocol (and an equivalent wired/wireless LAN transport over TCP). This spec covers the hex-frame command set documented in the Sharp/NEC Projector Control Command Reference Manual (BDT140013 Revision 7.1): power, input switching, mutes, picture/volume/aspect/gain adjustments, lens shift/zoom/focus and lens memory, shutter, freeze, eco mode, PIP/PbP, edge blending, and a broad set of status queries. All command payloads are byte sequences with a trailing checksum (low byte of the sum of preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists supported set: 115200/38400/19200/9600/4800 bps; default not stated
  # supported_baud_rates: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: RTS/CTS pins present on PC CONTROL D-SUB 9P but flow-control enable not stated
addressing:
  port: 7142  # TCP port for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable      # inferred: large catalogue of status request commands (078-*, 037-*, etc.)
  - routable       # inferred: 018 INPUT SW CHANGE and 319-10 AUDIO SELECT SET present
  - levelable      # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST present

Actions

# Hex frames verbatim from source. Trailing byte is checksum (low byte of sum of
# preceding bytes). <ID1>=Control ID, <ID2>=model code. "command:" shows literal

Events

# No unsolicited notifications documented. Device responds only to commands.
# UNRESOLVED: confirm no async event frames with device.

Macros

# No multi-step sequences explicitly documented.
# UNRESOLVED: populate if companion docs describe power-on/cooling sequences.

Safety

confirmation_required_for: []
interlocks: []
# Source notes operational lockouts (not safety interlocks per se):
#   - POWER ON: no other command accepted while power-on in progress.
#   - POWER OFF: no other command accepted during power-off incl. cooling time.
#   - ERROR STATUS (009) reports interlock-switch-open bit (DATA09 Bit1) and
#     foreign-matter / mirror-cover / lens-install / temperature errors, but the
#     source does not document an interlock procedure or required confirmation.
# UNRESOLVED: no explicit safety warnings, power-on sequencing requirements, or
# confirmation procedures stated in this refined source.

Notes

• Frame format: commands are hex byte sequences. Response prefix = command first byte + 20h (e.g. 02h→22h); error/NACK prefix = command first byte + A0h (e.g. 02h→A2h). <ID1> = Control ID set on projector; <ID2> = model code (varies by model); <CKS> = checksum = low-order byte of sum of all preceding bytes.
• Checksum worked example (source): 20h 81h 01h 60h 01h 00h → 20+81+01+60+01+00 = 103h → CKS = 03h.
• Error responses carry <ERR1> <ERR2> codes; see source §2.4 (e.g. 00h/00h unrecognized command, 00h/01h not supported by model, 01h/00h invalid value, 02h/0Dh command rejected because power off, 02h/0Fh no authority).
• Supported baud rates: 115200/38400/19200/9600/4800 bps (default not stated). Serial is full-duplex, RS-232C, D-SUB 9P cross cable on PC CONTROL port (pins 2 RxD / 3 TxD / 5 GND / 7 RTS / 8 CTS).
• LAN: wired (RJ-45, 10/100 Mbps auto) or optional wireless LAN unit; TCP port 7142 for command send/receive.
• Usage-time granularity: lamp/filter usage returned in one-second units but updated at one-minute intervals.
• Reference: Projector Control Command Reference Manual, BDT140013 Revision 7.1.

Spec ready. 53 commands covered (all rows in §2 command list). Hex payloads verbatim, checksums kept. Caveman mode loaded — chat stays terse, spec written normal per skill boundaries.
