Summary

Control spec for the Sharp/NEC NP Um351Wi Tm projector, covering RS-232C serial control (PC CONTROL D-SUB 9P) and wired/wireless LAN control. Source: "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). Commands use a binary hex protocol with frame header byte 20h/02h/03h/01h/00h, control ID + model code bytes, length byte, variable data, and a trailing checksum byte (low-order byte of sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # one of supported rates: 115200 / 38400 / 19200 / 9600 / 4800
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control / duplex not stated (full-duplex noted in source)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred from POWER ON / POWER OFF commands (015, 016)
  - routable        # inferred from INPUT SW CHANGE (018) and AUDIO SELECT SET (319-10)
  - queryable       # inferred from numerous REQUEST commands (009, 037, 037-3, 037-4, ...)
  - levelable       # inferred from PICTURE ADJUST / VOLUME ADJUST / LENS CONTROL adjustments

Events

# No unsolicited notifications described in source. All responses are solicited (returned after a command).
events: []

Macros

# No explicit multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    note: While power-on is in progress, no other command accepted.
  - command: power_off
    note: While power-off (including cooling time) is in progress, no other command accepted.
  - command: lens_control
    note: Continuous-drive values (7Fh, 81h) must be explicitly stopped by sending DATA02=00h.
# UNRESOLVED: no explicit power-on sequencing or interlock procedures stated beyond the per-command notes above.

Notes

  • Checksum (CKS): low-order one byte of the sum of all preceding bytes. Verified worked example: 20h+81h+01h+60h+01h+00h = 103h -> CKS=03h.
  • Command framing: header byte (00h-03h for commands; 20h/21h/22h/23h/A0h-A3h for responses) followed by command code, <ID1> <ID2>, length byte, data, <CKS>.
  • Responses are prefixed A0h/A1h/A2h/A3h (acknowledgement) or 20h/21h/22h/23h (data response) depending on command class.
  • Error codes: returned in <ERR1> <ERR2> on failure (see section 2.4 of source for full table; e.g. 02h 0Dh = "command cannot be accepted because the power is off", 02h 0Fh = "no authority for the operation").
  • Both serial and LAN control use the same binary command framing. TCP port 7142 stated for LAN. Default baud rate among the five supported rates is not specified.
  • Lens control: continuous drive values must be explicitly stopped; otherwise the lens keeps moving.

- "enumeration lives in Appendix \"Supplementary Information by Command\""
- "no explicit power-on sequencing or interlock procedures stated beyond the per-command notes above."
- "ID1 (control ID) and ID2 (model code) default/expected values for this model not stated in source"
- "Appendix \"Supplementary Information by Command\" not included in refined source — input terminal enum, aspect enum, eco mode enum, sub input enum values are referenced but not enumerated here"
- "firmware version compatibility not stated"
