INSTALLATION 6
Step 1. Before you plug in the power cord into
the unit, please verify that the voltage
rating of 110V/220V on the FUSE CLIP
located on the rear of the unit is the
same as the power outlet.
Step 2. Connect the female end of the power
cord to the DA1222AT and plug the
male end into the power outlet. The
power indicator LED on the front panel
will turn ON. This indicates that the unit
is operational.
Step 3. Connect the video output of the source
(computer, or interface, or any other
high-resolution source) to the input of
the DA1222AT using a high quality
coaxial-type cable. If the source offers a
VGA-type 15-pin HD connector, then
use a special cable - Altinex part #
MS8102CA (15-pin HD Male to 5 BNC
Male 6 feet cable) may be used.
NOTE: You may have to use an
interface (DA1910SX or VA6855WM)
with your source computer to provide
the appropriate signal format type and
to allow the use of a local monitor. Do
not use a Y-cable or monitor breakout
cable to connect the computer to the
DA1222AT because this will affect the
quality of the high-resolution input
signal.
Step 4. Connect the output channels of the
DA1222AT to the display devices (i.e.
monitors and/or projectors) using a
cable less than 10 feet with the
appropriate number of channels.
Step 5. Verify that the picture quality and
bandwidth on all displays is good.
CONGRATULATIONS! YOU ARE DONE.
OPERATION 7
The DA1222AT will operate successfully as long
as cables are attached properly and other
technical specifications are followed. There are no
other adjustments necessary to operate the unit.
