NEC XM29 Series RS-232 / IP control commands

Summary

NEC XM29 Series projector supporting both RS-232 serial and wired TCP/IP control interfaces. TCP port 7142 is used for LAN command communication. Serial supports multiple baud rates (115200/38400/19200/9600/4800 bps), 8 data bits, no parity, 1 stop bit. Commands include power control, input routing, picture/sound mute, lens positioning, and extensive status querying.

Events

# UNRESOLVED: no unsolicited event notifications documented in source

Macros

# UNRESOLVED: no multi-step sequences explicitly documented in source

Safety

confirmation_required_for: []

# UNRESOLVED: no explicit safety warnings or interlock procedures in source
# Note: Power on (015) blocks other commands while turning on
# Note: Power off (016) blocks other commands during cooling time

Notes

Serial cable is cross-pinned (null modem). TCP port 7142 stated for LAN control. Command protocol uses hex notation with checksum (CKS) calculated as low-order byte of sum of preceding bytes. Response format varies: success without data (22h/23h prefix), success with data (20h/23h/21h prefix), failure includes ERR1/ERR2 codes (A0h/A1h/A2h/A3h prefix).
