INSTALLING YOUR DA1907SX 6
Step 1. Connect the 9V 500mA AC adapter’s
output plug to the DA1907SX’s power
input connector - 2.5 mm DC Jack. Verify
the LED in the top right corner of the unit
on the front panel turn on and RED.
Step 2. Remove the protective port covers.
Connect the video output from the
computer to the computer input connector
on the DA1907SX using the provided
input VGA cable. If a longer cable is
required, please make sure that the cable
has video signals through coaxial cables
and this cable is not excessively long.
Step 3. Verify the LED on the face of the unit has
changes from RED to GREEN, indicating
an active source is applied. If the LED is
not green, the computer may not be
sending video signals. Check your
Computer’s manual if you are using a
laptop computer. You may have to send a
command that instructs the laptop to
output to the internal display and the
external video port simultaneously.
Step 4. Connect your display device (monitor or
projector) to the Main output. If needed,
connect a monitor to the Local Monitor
output port.
Step 5. Verify the picture quality on all displays is
good. If you are not receiving a signal,
make sure that the display is compatible
with the resolution of the computer
graphics card. Note: High levels of static
discharge under some conditions may
shutdown the unit. To reset the unit
simply, disconnect the input cable and
reconnect it.
OPERATION 7
There are no adjustments necessary to operate the
DA1907SX, the unit will operate successfully as
long as cables are attached properly and other
technical specifications are followed.
The DA1907SX offers a special LED on the front
panel that provides feedback to the user. When
power is connected to the DA1907SX, the LED will
turn RED. The LED will turn GREEN when an
active computer source is connected. This indicates
that it is receiving a proper signal by sensing the
presence of the sync portion of that signal.
TROUBLESHOOTING 8
We have carefully tested and have found no
problems in the supplied DA1907SX; however, we
would like to offer suggestions for the following:
8.1 LED IS NOT RED
The LED should be ON and RED when power is
applied and there is no video signal present. If
the LED is ON and GREEN, the unit is receiving
power and a SYNC signal.
Cause 1: No AC power.
Solution: Verify the Altinex supplied adapter is
plugged into a working AC outlet
and that the outlet has power.
Cause 2: Adapter is not plugged.
Solution: Verify the DC power plug coming
from the AC adapter is plugged all
the way into the DA1907SX.
Cause 3: The DA1907SX has a problem.
Solution: If there is AC power to the adapter
and the LED still does not turn on,
the DA1907SX or the power adapter
may require service. Call ALTINEX
at (714) 990-2300.
