7. Operation
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.
8. Troubleshooting Guide
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 output. If the LED is 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,
please 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 it 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.
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 it 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.
