Summary

Sharp/NEC NP Um351Wi WK projector control spec covering the binary RS-232C and wired/wireless LAN (TCP) control interface documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands use a hex-byte frame format with ID1 (control ID), ID2 (model code), and a trailing checksum byte. The spec enumerates power, input switching, mute, picture/volume/aspect/gain adjust, lens control and memory, shutter, freeze, eco mode, edge blending, PIP/PbP, and a broad set of status/error/lamp/filter/information queries.

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many status/error/information request commands present
  - routable     # inferred: INPUT SW CHANGE and audio select routing commands present
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST, LENS CONTROL present

Actions

# Frame: commands are hex bytes; <ID1> <ID2> are control/model IDs inserted by controller;
# trailing byte is checksum (low byte of sum of all preceding bytes).
# Fixed commands below include the precomputed checksum as last byte (verifiable: sum of bytes mod 256).

Events

# No unsolicited notifications documented. Device responds only to commands.
# UNRESOLVED: no event/notification mechanism described in source.

Macros

# No multi-step sequences explicitly documented.
# UNRESOLVED: populate from source, or remove section if not applicable.

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON: no other command accepted while power-on in progress."
  - "POWER OFF: no other command accepted during power-off including cooling time."
  - "cmd_009 error status includes interlock switch open (DATA09 Bit1) and cover errors."
# UNRESOLVED: no explicit power-on sequencing procedure or safety interlock steps stated in source beyond command-acceptance notes.

Notes

  • Command frame is hex bytes; response prefix is 20h/22h/23h (success, with class byte = command's first byte ORed), error prefix is A0h/A2h/A3h. <ID1> = control ID set on projector, <ID2> = model code (varies by model).
  • Checksum = low-order byte of the sum of all preceding bytes. Verified example: 20h 81h 01h 60h 01h 00h → sum=103h → CKS=03h.
  • Baud rate is selectable among 4800/9600/19200/38400/115200; controller and projector must match. baud_rate: 9600 is one valid selection, not a fixed default.
  • Error codes (ERR1/ERR2): 00h/00h=unrecognized command, 00h/01h=not supported by model, 01h/00h=invalid value, 01h/01h=invalid input terminal, 02h/0Dh=power off, 02h/0Eh=execution failed, 02h/0Fh=no authority, etc.
  • Pin assignment for PC CONTROL (D-SUB 9P): 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS (cross cable).
  • LAN: RJ-45, 10/100 Mbps auto-sensing, TCP port 7142.

53 actions, all hex payloads verbatim. Gaps marked UNRESOLVED: ID1/ID2 defaults, input-terminal/eco/aspect enum tables (referenced as Appendix, not in refined source), flow control, firmware version.
