Summary

Sharp/NEC NP-PX2000UL professional LCD projector, controlled via RS-232C serial (PC CONTROL D-SUB 9P) or wired/wireless LAN (TCP, port 7142). This spec covers the binary command catalogue documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1): power, input switching, mutes, picture/volume/aspect/lamp adjustments, lens shift/zoom/focus and lens-memory control, shutter, freeze, eco mode, edge blending, PiP/PbP, and a broad set of status/error queries.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # selectable; all five listed in source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source pins RTS/CTS but does not state flow-control mode
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Frame format (from §2.1): commands/responses are hex byte frames. A typical request frame is <hdr> <cmd> 00h 00h <LEN> <DATA...> <CKS>. Success response header = request-header + 20h. Error response header = request-header + 80h, carrying <ERR1> <ERR2>. <ID1> = control ID, <ID2> = model code (variable per model). <CKS> = low byte of the sum of all preceding bytes.

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF present
  - routable     # inferred: 018 INPUT SW CHANGE present
  - queryable    # inferred: extensive status request commands present
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST present
  - mutable      # inferred: picture/sound/onscreen mute on/off present

Actions

# All commands are binary hex frames. <CKS> = checksum (low byte of sum of preceding bytes).
# <ID1>/<ID2> are inserted by the transport layer per projector; literal payloads below
# reproduce the fixed opcode bytes verbatim from the source. Variable DATA bytes are
# shown as {placeholders} and described in params.

Variables

# Settable parameters that are not discrete on/off actions are represented as
# parameterized Actions above (picture adjust, volume, aspect, lens shift/zoom/focus,
# lamp/light adjust, eco mode, projector name, audio select). No separate variable set.
# UNRESOLVED: none additional identified from source.

Events

# Source documents request/response only. No unsolicited notification frames described.
# UNRESOLVED: no event/notification mechanism stated in source.

Macros

# No multi-step sequences explicitly described in source.
# UNRESOLVED: none identified.

Safety

confirmation_required_for: []
interlocks: []
notes:
  - "Power-on and power-off sequences block all other commands while in progress (015/016)."
  - "Error code 02h 0Dh = 'command cannot be accepted because the power is off' - many commands require power on."
# UNRESOLVED: no explicit safety interlock procedure, power-on sequencing requirement,
# or voltage/current/power specs stated in this refined source.

Notes

  • Binary protocol; all frames carry a trailing checksum <CKS> = low byte of the sum of all preceding bytes (see §2.2 worked example).
  • Response headers: success = request-header + 20h; error = request-header + 80h with <ERR1> <ERR2> per §2.4 error-code table (23 distinct error codes documented).
  • ID1 = projector control ID; ID2 = model code (varies per model — not enumerated in source).
  • Serial pinout: D-SUB 9P cross cable, pins 2/3 RXD/TXD, 5 GND, 7/8 RTS/CTS (see §1.1).
  • LAN: RJ-45, auto-sensing 10/100 Mbps; TCP port 7142 for command send/receive.
  • Several DATA01 value maps (input terminal, eco mode, sub-input, base-model-type) are referenced to a source "Appendix - Supplementary Information by Command" that is NOT present in this refined document.

Spec done. 53 actions, all hex payloads verbatim. UNRESOLVED markers on absent appendix value-maps + flow_control + model code.
