OPERATION  
7
Step 1. Connect the +9V AC adapter input to AC  
voltage and the output plug to the  
DA1907LX. Verify the LED in the top right  
corner of the unit’s front panel turns on  
and RED.  
The DA1907LX requires no adjustments for  
performance. Once set-up, the DA1907LX will work  
trouble-free without user intervention.  
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.
