INSTALLING YOUR  DA1931CT
6
Step 1. Determine the settings required for Gain, 
Sync-On-Green, Horizontal and Vertical 
Sync Polarity. If necessary to change the 
factory defaults, open the unit and set the 
switches per DIAGRAM 4 on page 9.
Step 2. Plug  the 9V power adapter into an AC 
outlet and then connect the other end to 
the Power input jack on the DA1931CT.
Step 3. Verify the LED near the top of the unit is 
illuminated red indicating power is 
applied.
Step 4. Connect the CAT-5/6 cable from the video 
output of the transmitter to the Input on 
the DA1931CT.
Step 5. Verify the power LED at the top of the unit 
changes to green, indicating a sync signal 
has been detected.
Step 6. Connect the stereo audio output from the 
DA1931CT to the receiving audio device.
Step 7. Connect the receiving monitor to the 
applicable 
DA1931CT
video 
output 
connector, RGBHV/YPbPr, S-Video, or 
C-Video depending on the input type to 
the transmitter.
Step 8. Verify the picture quality on the receiving 
monitor is equivalent to the quality as 
displayed on the local monitor at the 
transmitter. If the quality of the image is 
poor or non-existent, it may be necessary 
to adjust the video  equalization on the 
DA1931CT and/or  DA1930CT. See the 
Operation section that follows for details.
NOTE:
Some monitors may not display 
an image at all if the equalization 
is not within its specific range. 
Use 2 people when setting up 
the transmitter and receiver, one 
person at each end of the 
transmission to view the display 
while adjustments are made. 
OPERATION
7
The DA1931CT requires only one adjustment to be 
made for optimal performance. Video Equalization 
is required for long cable lengths and may be 
adjusted to fine-tune the video display.
7.1  VIDEO EQUALIZATION
Video Equalization is provided to fine-tune the 
displayed image on the remote display. The 
equalization adjustments on the DA1931CT
Receiver and DA1930CT Transmitter work 
together  in providing equalization for maximum 
cable lengths. For example, for cable runs less 
than 50 ft (15 m), both equalization settings may 
be set to approximately minimum, whereas 
maximum cable will see equalization settings at 
about the 3/4 position.
TROUBLESHOOTING GUIDE
8
We have carefully tested and have found no 
problems in the supplied DA1931CT. 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 adapter is plugged into a 
working AC outlet and that the outlet 
has power.
Cause 2:
Adapter is not plugged into 
DA1931CT.
Solution:
Verify the DC power plug coming 
from the AC adapter is plugged all 
the way into the DA1931CT.
Cause 3:
The DA1931 has a problem.
Solution:
If there is AC power to the adapter 
and the LED still does not turn on, 
the DA1931CT or the power adapter 
may require service, call ALTINEX 
at (714) 990-2300.
