NEC NEC NP Series Control Spec

Summary

NEC NP Series projectors support RS-232C serial control and TCP control over wired or wireless LAN. This spec covers power, input, mute, picture, volume, lens, projector status, information, eco, edge blending, PIP/PBP, and audio-selection commands.

Transport

  - serial
  - tcp
addressing:
  port: 7142
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none

    behavior: No other command can be accepted during power-on, power-off, or cooling time.
  - condition: lens_continuous_drive
    behavior: Lens continuous movement stops when lens control command sends DATA02 00h.
  - condition: picture_mute_active
    behavior: Input-terminal or video-signal switch turns picture mute off.
  - condition: sound_mute_active
    behavior: Input-terminal switch, video-signal switch, or sound-volume adjustment turns sound mute off.
  - condition: onscreen_mute_active
    behavior: Input-terminal or video-signal switch turns onscreen mute off.

Notes

Commands use hexadecimal byte sequences. Source defines ID1 as configured control ID, ID2 as model-dependent code, LEN as data length, and CKS as low-order byte of the sum of preceding bytes.

summary: "All 54 spec actions match source commands literally; transport parameters verified; one-to-one coverage. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "Source does not provide a single model-specific protocol profile; model code and control ID vary by projector model."
- "no unsolicited notification format documented in source"
- "no explicit multi-step macro documented in source"
- "Exact model-specific ID2 values, input-terminal values, aspect values, eco-mode values, PIP/PBP sub-input values, supported parameters, and firmware compatibility are not stated."
