NEC 42XP10 Control Spec

Summary

The NEC 42XP10 is a professional projector supporting both RS-232C serial and wired LAN (TCP/IP) control. This spec covers the full command set including power control, input routing, picture/sound mute, lens positioning, eco mode, and comprehensive status queries. Control is via hexadecimal command packets with checksum.

Notes

Serial baud rate is selectable: 115200/38400/19200/9600/4800 bps. Default not stated in source — baud_rate left null.

Command format: 20h <ID1> <ID2> <LEN> <DATA> <CKS> for commands; A0h/A2h/A3h prefix in responses. Checksum = low-order byte of sum of all preceding bytes.

Power ON and Power OFF commands block all other commands while executing (including cooling time).

Input terminal values and aspect values are documented in an Appendix not included in this source document — those parameter enums marked as "See appendix."

Lens position drive commands (7Fh/81h) continue until explicit Stop (00h) is sent.
