Summary

NEC PXVP1 Series projector with binary control protocol over RS-232C serial and TCP/IP (LAN). Commands are hex-encoded with checksum. Covers power, input switching, picture/audio adjustment, lens control, shutter, freeze, eco mode, edge blending, PIP, and extensive status queries.

Events

# UNRESOLVED: no unsolicited notification events described in source

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# Source notes: power on/off commands block all other commands during execution
# (power-on sequence and cooldown period). No explicit safety interlocks documented.
# UNRESOLVED: no explicit power-on sequencing or interlock procedures found in source

Notes

  • Binary protocol: all commands are hex byte sequences with a trailing checksum byte.
  • Checksum = low-order byte of sum of all preceding bytes.
  • Commands include ID1 (control ID set on projector) and ID2 (model code) in responses.
  • Multiple baud rates supported (115200/38400/19200/9600/4800) — default not stated.
  • TCP port 7142 for LAN control.
  • Input terminal, eco mode, aspect ratio, and base model type value mappings reference an appendix not included in the source document.
  • Two-lamp models support Lamp 2 queries (DATA01=01h).
  • Lamp remaining life can return negative value when replacement deadline exceeded.
  • Lens control supports both timed (0.25s/0.5s/1s) and continuous drive modes; continuous drive requires explicit stop command.
