NEC 2 R Series Control Spec

Summary

NEC 2 R Series is a projector supporting both RS-232C serial and wired LAN (TCP/IP) control interfaces. The serial interface supports configurable baud rates from 4800 to 115200 bps. The LAN interface uses TCP port 7142. Both interfaces use the same command set with hexadecimal encoding, control ID, model code, and checksum validation.

Notes

Command format: All commands use hexadecimal notation with structure: [Header] [Command code] [ID1] [ID2] [Data length] [Data] [Checksum]. Response headers: A0h (success with data), A2h (success no data), A3h (error). Control ID (ID1) and Model code (ID2) must match projector settings.

Baud rate selection: The projector auto-detects or can be configured for 115200/38400/19200/9600/4800 bps. Default not stated.

LAN control: TCP port 7142 used for both sending and receiving commands. Wired LAN supports 10/100 Mbps auto-negotiation.

Key codes: Remote key codes include POWER ON (02h), POWER OFF (03h), AUTO (05h), MENU (06h), UP/DOWN/LEFT/RIGHT (07h-0Ah), ENTER (0Bh), EXIT (0Ch), MUTE (13h), COMPUTER1 (4Bh), COMPUTER2 (4Ch), VIDEO1 (4Fh), S-VIDEO (51h), VOLUME UP/DOWN (84h-85h), FREEZE (8Ah), ASPECT (A3h), SOURCE (D7h), LAMP MODE/ECO (EEh).

Input terminal hex values (partial): COMPUTER=01h, COMPUTER2=02h, VIDEO=06h, S-VIDEO=0Bh, HDMI=A1h or 1Ah, DVI-D=9Ch, NETWORK/LAN=20h, DisplayPort=A6h, HDBaseT=BFh, USB-B=22h.

Aspect mode hex values: AUTO=00h, WIDE ZOOM=01h, 16:9=02h, NATIVE=03h, 4:3=04h, 15:9=05h, 16:10=06h, ZOOM=07h or 08h, FULL=09h or 10h.

Eco mode hex values: OFF=00h, Normal=00h or 01h, ECO=02h or 03h, AUTO ECO=01h, ON=01h, LONG LIFE=04h, BOOST=05h, SILENT=06h.

Standby mode requirements: Some models require specific standby modes for serial/LAN control. Serial supports: Normal, Active, Eco, NORMAL, Network Standby, Sleep, OFF, ON, Standby Power On. LAN supports: Normal, NORMAL, Network Standby, Sleep, HDBaseT Standby, OFF, ON, Standby Power On. Supported modes vary by model.
