NEC V462-AVT-R Series Control Spec

Summary

NEC V462-AVT-R Series projector supporting both RS-232C serial and wired LAN (TCP/IP) control. Serial communication at 115200/38400/19200/9600/4800 bps, 8N1. LAN uses TCP port 7142. Supports power control, input routing, mute functions, picture adjustment, lens control, and extensive status querying.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142  # stated: "Use TCP port number 7142 for sending and receiving commands"
serial:
  baud_rate: 115200  # stated: supports 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

# inferred from command examples:
# - powerable: power on/off commands present (015, 016)
# - routable: input switching command present (018)
# - queryable: many status/info request commands present
# - levelable: volume adjust, picture adjust commands present

Notes

Serial baud rate is configurable (115200/38400/19200/9600/4800). Device uses Checksum (CKS) calculated as low-order byte of sum of preceding bytes. Commands use Control ID (ID1) and Model code (ID2) parameters. Responses include ERR1/ERR2 error codes. For input terminal values, aspect values, eco mode values, signal types, and audio select values, see the Appendix tables in the source document.

Error code combinations from source:

• 00h/00h: command not recognized
• 00h/01h: command not supported
• 01h/00h: specified value invalid
• 01h/01h: specified input terminal invalid
• 01h/02h: specified language invalid
• 02h/00h: memory allocation error
• 02h/02h: memory in use
• 02h/03h: specified value cannot be set
• 02h/04h: forced onscreen mute on
• 02h/06h: viewer error
• 02h/07h: no signal
• 02h/08h: test pattern or filter displayed
• 02h/09h: no PC card inserted
• 02h/0Ah: memory operation error
• 02h/0Ch: entry list displayed
• 02h/0Dh: command cannot be accepted because power is off
• 02h/0Eh: command execution failed
• 02h/0Fh: no authority for operation
• 03h/00h: incorrect gain number
• 03h/01h: specified gain invalid
• 03h/02h: adjustment failed
