InFocus IN72 Projector Digital Connections Manual

Digital connections

The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) con- nectors are digital and yield the highest quality image. It is common for these signals to be encrypted with HDCP (high-bandwidth digital-content protection). Your new projector ships standard with decryption codes so you can enjoy these high quality, all digital images.

This projector uses the M1-DA connector, which has the following advan- tages:

•allows connection to a digital DVI source

•allows connection to a component source

•allows connection to an analog computer source

•carries a USB control signal which allows you to easily update your projector’s software as enhancements become available.

•has output pins that can power accessories.

The IN76 and IN78 are HDTV (High Definition Television) monitors, mean- ing they have vertical scanning lines of 720 progressive, 1080 interlaced or higher. The IN72 and IN74 are EDTV (Enhanced Definition Television) monitors, meaning they have vertical scanning lines of 480 progressive or higher. HD content can be displayed on an EDTV monitor, the resolution is just less than that of an HDTV.

DVI connection

If your video device uses a DVI connector, plug the DVI end of an M1-DA cable into the video-out connector on the video device. This connector may be labeled “To Monitor” on the video device. Plug the M1-DA end of the cable into the M1-DA/DVIconnector on the projector.

HDMI connection

HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI provides an interface between sources, such as set-top boxes, DVD players, and receivers and your projector. Plug an HDMI cable into the video-out connector on the video device and into the HDMI connector on the projector.

An M1-DA to HDMI adapter is included with the IN78. This plugs inot the

M1-DA connecotr and allows a second HDMI source to be connected. Note: DVI, VESA, and USB connections are not available when adapter is con- nected.

Note that the projector has no audio capabilities, so audio signals trans- ferred through HDMI will not be audible.

Computer connections

You can connect a computer’s VGA connector to the M1-DA/DVIinput on the projector using an M1-A cable.

RS-232 connections (IN74/IN76/IN78 only)

You can control the projector from an LCD control panel or computer by connecting an RS-232 cable to the projector’s Serial control connector. Spe- cific RS-232 commands can be found in the Service section of our website at www.infocus.com/support.
