NEC X461S-PC Series Control Spec

Summary

NEC X461S-PC Series projector controlled via the NEC PC CONTROL (RS-232C, D-SUB 9P) serial port or wired LAN (TCP port 7142), using the binary frame protocol defined in NEC's Projector Control Command Reference Manual (BDT140013 Rev 7.1). This spec covers power, input switching, mute, picture/volume/aspect adjustment, lens and lens-memory control, and the full status/query command set.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: "115200/38400/19200/9600/4800"  # source lists all five supported rates
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (RTS/CTS pins wired per pin table)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF commands present
  - routable     # inferred: 018 INPUT SW CHANGE command present
  - queryable    # inferred: extensive request command set (009, 037, 078, 097, 305, ...)
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST commands present

interlocks:
  - "While 015 POWER ON is executing, no other command is accepted."
  - "While 016 POWER OFF is executing (including cooling time), no other command is accepted."
  - "015 POWER ON via serial or LAN requires the projector to be in a supported standby mode (serial: Normal, Active, Eco, NORMAL, NETWORK STANDBY, SLEEP, OFF, ON, STANDBY POWER ON; wired LAN: Normal, NORMAL, NETWORK STANDBY, SLEEP, HTBaseT STANDBY, OFF, ON, STANDBY POWER ON; supported modes vary by model)."

Notes

• Command frame format: <type> <code> 00h 00h <LEN> <DATA...> <CKS>. Command type bytes: 00h/01h/02h/03h; response types 20h/21h/22h/23h mirror them; error responses use A0h/A1h/A2h/A3h with ERR1/ERR2 payload.
• ID1 = control ID set on the projector; ID2 = model code (varies by model) — both appear in response frames, not command frames.
• Checksum: sum all preceding bytes, use low-order byte (e.g. 20h+81h+01h+60h+01h+00h=103h → CKS=03h).
• Serial settings: RS-232C, 115200/38400/19200/9600/4800 bps, 8 data bits, no parity, 1 stop bit, full duplex. PC CONTROL port is D-SUB 9P (RxD pin 2, TxD pin 3, GND pin 5, RTS pin 7, CTS pin 8).
• LAN: wired RJ-45, 10/100 Mbps auto-switching, TCP port 7142 for send/receive.
• Picture mute / onscreen mute auto-clear on input terminal switch or video signal switch; sound mute also auto-clears on volume adjustment.
• Usage-time values (lamp, filter) update at one-minute intervals though reported in one-second units.
• Lamp remaining life (%) returns negative after replacement deadline exceeded.
• 053 LENS CONTROL continuous drive (7Fh/81h) stopped by sending 00h; lens can be driven without stop by repeating the same command.
• Full ERR1/ERR2 error code table in source section 2.4 (00h-03h ranges: unrecognized command, unsupported, invalid value, invalid input, memory errors, forced onscreen mute, no signal, power off, execution failed, no authority, gain errors).
