ABOUT YOUR DA1931CT 2
DA1931CT
CAT-5 TO VGA + AUDIO RECEIVER
The DA1931CT provides a means of receiving
computer video and audio signals over twisted pair
(CAT-5) type cable when used together with an
ALTINEX Twisted Pair Video Transmitter, such as
the DA1930CT.
The DA1931CT is compact and easy to use. The
DA1931CT is able to receive one of the video
sources, such as VGA, Component Video, S-Video
or C-Video along with Stereo Audio transmitted
over the CAT-5/6 cable from the DA1930CT or
equivalent Transmitter.
The DA1931CT provides both Audio and Video
outputs. The DA1931CT offers a female 15-pin HD
output for RGBHV/YPbPr signals, a 4 pin Mini-Din
connector for S-Video and an RCA connector for
Composite Video Output. A 5 pin terminal block is
available for balanced stereo output and a 3.5mm
jack is used for unbalanced stereo output.
The unit also offers hardware Video Equalization
for transmission lengths up to 400 feet. The Video
Equalization work in conjunction with the Video
Equalization on the transmitter. There is also a
Signal Detect feature which shows when an input
signal is present.

INSTALLING YOUR DA1931CT 6
Step 1. Determine the settings required for Gain,
Sync On Green, Horizontal Sync Polarity
and Vertical Sync Polarity. If necessary to
change the factory defaults, open the unit
and set the switches per DIAGRAM 4 on
page 8.
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 CAT-5 Transmitter to the
CAT-5 Input port 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 audio receiving device.
Step 7. Connect the receiving monitor to the
applicable DA1931CT Video Output
connector, either 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.
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.
Typically, for short cable runs the equalization
will be set to near minimum. Cable lengths up to
400 feet will require near maximum equalization.
The equalization adjustments on the DA1931CT
Receiver and DA1930CT Transmitter work
together to provide equalization for maximum
cable lengths. For example, for cable runs less
than 50 feet, both equalization settings may be
set to approximately minimum, since on the
short distances no equalization is required.
Where as cable runs of 400 feet will see
equalization settings at about the three-quarter
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.
8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the
DA1931CT 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 monitor. If the display is
good, call ALTINEX at (714)
990-2300.
8.3 NO SOUND
Cause 1: The source has a problem.
Solution: Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no sound, see Cause 2.
Cause 2: The volume is too low.
Solution: Increase the AUDIO GAIN toward
maximum. If there is still no sound
present, see Cause 3.
Cause 3: Cable connections are incorrect.
Solution: Make sure that cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no sound, see Cause 4.
Cause 4: The receiving device has a
problem.
Solution: Make sure the receiving device has
power and is turned ON. If there is
still no sound, please call Altinex at
(714) 990-2300.
8.4 NO REMOTE IMAGE
Cause 1: The source has a problem.
Solution: Check the image on the local
monitor and verify the quality is
good. If the local image is good, see
Cause 2.
Cause 2: Video equalization required.
Solution: Adjust the VIDEO EQUALIZATION
on the DA1931CT. Long cable runs
may require adjustment on both the
DA1930CT and the DA1931CT.
In general, cable runs less then 50
feet require little or no video
equalization and should be set to
minimum. Cable runs up to 400 feet
will require maximum equalization
on both the transmitter and receiver.
SPECIAL APPLICATION
400-0199-003 11
8.5 RECEIVING DISPLAY QUALITY IS POOR
Cause 1: The source has a problem.
Solution: Check the image on the local
monitor and verify the quality is
good. If the local image is good, see
Cause 2.
Cause 2: Video equalization required.
Solution: Adjust the VIDEO EQUALIZATION
on the DA1931CT. Long cable runs
may require adjustment on both the
DA1930CT and the DA1931CT. If
the image is still not correct, call
ALTINEX at (714) 990-2300.
