Summary

NEC X462S Series projector supporting both RS-232C serial and wired LAN (TCP/IP) control interfaces. Serial communication uses RS-232C at configurable baud rates up to 115200 bps. LAN control uses TCP port 7142. The projector supports power control, input routing, picture/sound muting, lens positioning, and comprehensive query commands for status monitoring.

Notes

The X462S Series supports both serial and LAN control simultaneously. Standby mode must be correctly configured for the control method used — some models require specific standby modes (Normal, Eco, Network Standby, Sleep, etc.) to receive commands via serial or LAN. Two-lamp operations are referenced in some commands (037-4, 053-7) but may not apply to all X462S models. Commands 078-3 and 305-3 reference an Appendix for supplementary values not included in this source document.
