NEC X463UN-R Series Control Spec

Summary

NEC X463UN-R 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 adjustment, mute functions, lens control, eco mode, and queryable status variables. Both serial (115200/38400/19200/9600/4800 bps, 8N1) and TCP (port 7142) transports are documented.

Variables

# All settable parameters are covered by Actions above.
# UNRESOLVED: no discrete Variables section applicable - all parameters use action commands.

Events

# UNRESOLVED: no unsolicited event notifications documented in source.

Macros

# UNRESOLVED: no multi-step macro sequences documented in source.

Notes

Command format: All commands use hex notation with the structure: [HEADER] [CMD] [ID1] [ID2] [LEN] [DATA...] [CKS]. Checksum (CKS) is low-order byte of sum of all preceding bytes.

Serial configuration: The source lists multiple baud rates (115200/38400/19200/9600/4800). The highest (115200) is listed first but the projector likely ships at 9600. No explicit "default" is stated.

LAN port: TCP 7142 is stated for LAN control. No mention of HTTP/REST protocol — commands are sent raw over TCP.

Input terminal values: Appendix lists many hex codes for input selection (018 command). Some codes vary by model (e.g., HDMI can be A1h or 1Ah). Full model-specific appendix not included.

Aspect values: Some aspect modes have multiple hex codes (e.g., ZOOM=07h or 08h, WIDE SCREEN=02h or 03h, FULL=09h or 10h) — model-dependent.

Eco mode values: Eco mode codes vary significantly by model (OFF=00h, NORMAL=00h or 01h, ECO=02h or 03h, etc.) — model-specific appendix required.

Standby modes: Some models require specific standby mode settings to accept serial or LAN commands while in standby. Modes listed: Normal, Active, Eco, NORMAL, NETWORK STANDBY, SLEEP, OFF, ON, STANDBY POWER ON for serial; Normal, NORMAL, NETWORK STANDBY, SLEEP, HTBaseT STANDBY, OFF, ON, STANDBY POWER ON for LAN. Supported modes vary by model.
