NEC NP-PA Series Control Spec

Summary

NEC NP-PA Series professional installation projectors. This spec covers binary control via RS-232C serial and TCP/IP network connections. The protocol uses hex-encoded command frames with checksum validation, supporting power control, input switching, picture/audio adjustment, lens control, shutter, freeze, eco mode, edge blending, and extensive status queries.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142  # TCP port for network control
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: UNRESOLVED  # Source does not specify flow control.
auth:
  type: UNRESOLVED  # Source does not specify an authentication method.

Traits

traits:
  - powerable    # power on/off commands (015, 016)
  - routable     # input switching command (018)
  - queryable    # extensive status request commands (037, 078, 305)
  - levelable    # volume, brightness, contrast, color, hue, sharpness, lamp adjust (030-1, 030-2, 030-15)
  - mutable      # picture mute, sound mute, onscreen mute (020-025)

Events

# UNRESOLVED: no unsolicited event/notification mechanism described in source.
# All responses are synchronous replies to commands.

Macros

# UNRESOLVED: no multi-step macro sequences described in source

Safety

confirmation_required_for: []
interlocks: []
notes: >
  Power ON and Power OFF commands block all other commands during execution
  (including cooling period for power off). The error status request (009) provides
  bit-flagged hardware error detection including cover, fan, temperature, lamp,
  and interlock switch status.
# UNRESOLVED: source mentions interlock switch (DATA09 Bit1) but no explicit
# interlock procedure is documented in the command reference.

Notes

• All commands and responses are binary (hex-encoded) with a simple additive checksum (low byte of sum of all preceding bytes).
• Commands include <ID1> (control ID) and <ID2> (model code) parameters in responses.
• Error responses use a standard format with ERR1/ERR2 codes. See error code table in source Section 2.4.
• Lens control supports both timed drive (0.25s/0.5s/1s) and continuous drive modes. Continuous drive requires an explicit stop command.
• Input terminal hex codes and eco mode values vary significantly across NP-PA sub-models. Consult the supplementary tables in Sections 4 for exact mappings.
• Lamp usage time and filter usage time are returned in seconds but updated at one-minute intervals.
• Some models cannot receive commands in standby mode.

Verification Summary

verdict: verified
checked_at: 2026-10-07T15:43:21.947Z
matched_actions: 54
action_count: 54
confidence: medium
summary: "All 54 action units match source frames and shapes, transport values are supported, and the spec covers every source command (about 53), so the ratio is above 0.9. (14 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "exact model-specific input terminal hex codes vary by model — see supplementary tables in source"
- "eco mode values vary by model subgroup"
- "some models cannot receive commands in standby mode — see Appendix \"Standby Mode setting for receiving commands\""
- "source section 3.53 gives 00h=the terminal specified in DATA01, 01h=BNC, 02h=COMPUTER; the appendix gives model-specific DATA02 mappings that conflict with this enumeration.\""
- "range not stated; use gain_parameter request to discover"
- "no unsolicited event/notification mechanism described in source."
- "no multi-step macro sequences described in source"
- "source mentions interlock switch (DATA09 Bit1) but no explicit"
- "exact control ID (ID1) and model code (ID2) values not specified in source — likely configured per projector"
- "supported input terminal codes are model-specific; only representative examples listed"
- "eco mode, aspect ratio values are model-specific"
- "maximum/minimum values for picture and volume adjustment ranges not stated; must be queried via gain parameter request (060-1)"
- "standby mode command reception capability varies by model"
- "document revision is BDT140013 Rev 7.1 / BDT140014 Rev 29.0; firmware compatibility ranges not stated"
