NEC X463UN Series RS-232 / IP control commands

Summary

The NEC X463UN Series is a projector supporting both RS-232C serial and wired LAN (TCP/IP) control. This spec covers the complete command set including power control, input routing, picture/sound adjustment, lens control, and status queries. Communication uses a binary protocol with checksum validation.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142  # TCP port for LAN control; stated in source
serial:
  baud_rate: 115200  # source lists: 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: hardware flow control pins present (RTS/CTS) but usage not documented
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable       # power on/off commands present
- routable        # input switching command present
- queryable       # multiple status/information request commands present
- levelable       # picture adjust, volume adjust, brightness, contrast, etc.

Safety

confirmation_required_for: []
interlocks:
  - description: Some models require specific standby mode settings to accept commands via serial or LAN. Supported standby modes vary by model - see Appendix "Standby Mode settings" in source.
  - description: During power-on or power-off sequence, no other commands are accepted by the projector.
# UNRESOLVED: safety warnings for lamp replacement, temperature limits, or dust accumulation not found in source

Notes

The protocol uses a binary format with checksum. Command structure: [HEADER] [MODEL] [CMD] [DATA...] [CKS] where CKS is low-order byte of sum of all preceding bytes. Query commands use header byte 00h or 03h; control commands use 01h or 02h. Response codes: success=0000h in data; failure returns ERR1/ERR2 codes.

Input terminal and aspect values vary across models. The Appendix in the source document provides hex code mappings but notes some values are model-dependent.
