DVI DA2 and DVI DA4 • Introduction 1-3
DVI DA2 and DVI DA4 Features
External power supply — The DVI DA2 and DVI DA4 are
powered by external 12 VDC power supply (provided with the
units).
DVI-D input —
Both distribution amplifiers accept one single
link DVI-D input, with a resolution range up to 1920 x 1200 or
1080p @ 60 Hz.
Input Equalization — Input Equalization (EQ) conditions the
input signals to ensure the integrity of the signals delivered to
the output devices.
DVI-D outputs —
The units drive two (DVI DA2) or four
(DVI DA4) single link DVI-D output signals.
DDC routing to local monitor — Output 1 is used as a DDC
reference and is labeled "Local Output" for easy reference. The
video source uses the bidirectonal DDC to communicate with
the local monitor, which allows the source to determine the
resolution and refresh rate of the signal that it sends.
N Since output 1 is used as the reference, all other display
devices must be capable of handling resolutions equal to
or greater than that of the local monitor.
N The actual signal transmission distance can vary greatly
and depends on signal resolution, cable type, cable
quality, graphics card and the display used in the system.
Versatile mounting options — Both units are 1U high, 3"
(7.62 cm) deep, and 1/2 rack (8.7" or 22.1 cm) wide, allowing
them to be conveniently mounted in a rack, under a desk or set
on a tabletop.
