4.1 INPUT/OUTPUTS
The outputs of the
DA1322AT
allow signals to be
driven through 100 feet or more of cable
depending on cable quality and the source signal
resolution. The
DA1322AT
uses 5-BNC
connectors for each input and output representing
red, green, blue, and separate horizontal and
vertical sync. When passing an RGBS format
signal, simply use the horizontal channel to pass
composite sync.
4.2 CHANNEL DIP SWICTHES
Each channel (RED, GREEN, and BLUE) of the
DA1322AT
has four dip switches: AC/DC, TERM,
GAIN, and EQLZ.
The
AC/DC
switch is used to select AC or DC
coupling of video signal through a distribution
amplifier.
The
TERM
switch is used to terminate or
unterminate RED, GREEN, & BLUE inputs with 75
Ohms.
The
GAIN
switch is used to set gain to 1 or 1.3.
The
EQLZ
switch is used to compensate for
longer cable runs.

4.3 SYNC CONTROL SWITCHES
The
DA1322AT
has separate Sync control
switches: TERM H, C SYNC, TERM V, and SYNC
G.
The
TERM
H
switch is used to terminate or
unterminate horizontal sync input with 75 Ohms.
The
TERM
V
switch is used to terminate or
unterminate vertical sync input with 75 Ohms.
The
C Sync
switch is used with composite sync.
The
Sync G
switch is used with sync on green.
4.4 BANDWIDTH
Offering a minimum video bandwidth of 350 MHz
and typical bandwidth close of 500 MHz, the
DA1322AT
allows even very high resolution video
signals to pass without degrading the image
quality.
4.5 POWER
Designed with a universal power input connector,
the
DA1322AT
offers a built-in linear power supply
with continuous operation at 95V to 240V.
