Digital connections
The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) connectors are digital and yield
the highest quality image. It is common for these signals to be encrypted with HDCP (high-band
width 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 advantages:
• 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
HDMI 1.3 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. To display HDMI 1.3 with its deep color and 30-bit detail, a HDMI 1.3 source is
needed. Please note the HDP410, HDP420 and HDP460 have no audio capabilities at all.
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/DVI connector on the projector.
Note that the
projector has no audio capabilities, so audio signals transferred through HDMI
will not be audible.
Computer connections
You can connect a computer’s VGA connector to the M1-DA/DVI input on the projector using an
M1-A cable.
RS-232 connections
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.
