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.
