NEC X462UN-R Series Control Spec

Summary

Projector control via RS-232C serial and wired LAN (TCP/IP). Supports power control, input routing, picture/sound mute, volume, aspect adjustment, lens control, eco mode, and comprehensive query commands for status monitoring. Serial supports 115200/38400/19200/9600/4800 bps; LAN uses TCP port 7142.

Variables

# UNRESOLVED: many parameters are settable but only via action commands;
# no discrete Variable entries identified in source beyond query responses

Events

# UNRESOLVED: no unsolicited event notifications documented;
# device only responds to commands

Macros

# No explicit multi-step macros defined in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: power on/off commands block other commands during execution;
# no explicit safety warnings or interlock procedures in source
# Note: power on requires specific standby modes depending on control interface

Notes

Serial supports 5 baud rates; host must match device configuration. During power-on or power-off sequence (including cooling time), no other commands are accepted. Checksum (CKS) is low-order byte of sum of all preceding data bytes. Some commands require specific standby modes for the device to receive them — varies by model. Source document titled "Projector Control Command Reference Manual" covers both serial and LAN control.
