TROUBLESHOOTING GUIDE
8
We have carefully tested and have found no
problems in the supplied DA1907LX; however, we
would like to offer suggestions for the following:
Step 2. Connect the video output from the
computer to the computer input connector
on the DA1907LX using the cable
provided. If a longer cable is required,
make sure that the cable uses internal
coaxial cables and that the cable is not
excessively long.
8.1 LED IS NOT RED
The LED should be ON and RED when power is
applied and ON and GREEN when the unit is
receiving power and a SYNC signal.
Step 3. Verify the LED on the face of the unit
changes from RED to GREEN indicating
an active signal is present. If the LED is
not GREEN, the computer may not be
sending video signals.
Cause 1: There is no AC power.
Solution: Verify the supplied adapter is
plugged into a working AC outlet
and that the outlet has power.
NOTE: If using a laptop computer, the
laptop may need to be set to
output to the display to the
external video port manually.
Cause 2: The adapter is not connected.
Solution: Verify the DC power plug coming
from the AC adapter is plugged all
the way into the DA1907LX.
Step 4. Connect the display devices (monitors
and/or projectors) to Outputs 1 & 2 of the
DA1907LX.
Cause 3: The DA1907LX has a problem.
Solution: If there is AC power to the adapter
and the LED still does not turn on,
the DA1907LX or the power adapter
may require service. Call ALTINEX
at (714) 990-2300.
Step 5. Verify the picture quality on both displays
is good. If there is no signal, make sure
that the display is compatible with the
resolution of the computer graphics card.
8.2 LED IS NOT GREEN
Step 6. The DA1907LX is now operational.
Cause 1: There is no power.
Solution: Disconnect the video input from the
DA1907LX and verify the LED is ON
and RED indicating power is
present. Reconnect the computer's
video output. If the LED is still not
GREEN see Cause 2.
Cause 2: There is no Sync signal.
Solution: Verify the computer output is
operating correctly by connecting it
directly to a local monitor. If the
display is good, call ALTINEX at
(714) 990-2300.
