5. About Your DA1931CT
The DA1931CT rovides a means of receiving com uter video and audio signals over Twisted Pair ty e (CAT-5) cable when used together with an ALTINEX
Twisted Pair Video Transmitter, such as the DA1930CT.
The DA1931CT is com act and easy to use. The DA1931CT is able to receive one of the video sources such as RGBHV, com onent video, S-Video, or com osite
video, along with stereo audio† transmitted over the Twisted Pair cable from the DA1930CT or equivalent transmitter.
The DA1931CT rovides both audio and video out uts. The DA1931CT offers a female 15- in HD out ut for RGBHV/YPbPr signals, a 4- in Mini DIN connector
for S-Video and an RCA connector for com osite video out ut. A 5- in terminal block is available for balanced stereo out ut and a 3.5 mm jack is used for
unbalanced stereo out ut.
The unit also offers hardware video equalization for long cable lengths. The video equalization works in conjunction with the equalization on the transmitter for
o timal erformance. There is also a Signal Detect feature which shows when an in ut signal is resent.
The latest generation of Twisted Pair devices uses an innovative, atented technology* develo ed by ALTINEX. The new signal rocessing technology allows
transmitting and receiving fully equalized com uter video signals, stereo, and audio signals over long distances.

7. Operation
The DA1931CT requires only one adjustment to be made for o timal
erformance. Video Equalization is required for long cable lengths and
may be adjusted to fine tune the video dis lay.
7.1 Video Equalization
Video Equalization is rovided to fine tune the dis layed image on the
remote dis lay. The equalization adjustments on the DA1931CT Receiver
and DA1930CT Transmitter work together in roviding equalization for
maximum cable lengths. For exam le, for cable runs less than 50 ft (15 m),
both equalization settings may be set to a roximately minimum, whereas
maximum cable will see equalization settings at about the 3/4 osition.
8. Troubleshooting Guide
We have carefully tested and have found no roblems in the su lied
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 ower is a lied and there is no video
signal resent. If the LED is on and green, the unit is receiving ower and a
sync signal.
Cause 1: No AC ower.
Solution: Verify the ada ter is lugged into a working AC outlet and
that the outlet has ower.
Cause 2: Ada ter is not lugged into DA1931CT.
Solution: Verify the DC ower lug coming from the AC ada ter is
lugged all the way into the DA1931CT.
Cause 3 The DA1931 has a roblem.
Solution: If there is AC ower to the ada ter and the LED still does not
turn on, the DA1931CT or the ower ada ter may require
service, call ALTINEX at [phone].
8.2 LED is not green
Cause 1: There is no ower.
Solution: Disconnect the video in ut from the DA1931CT and verify the
LED is on and red indicating ower is resent. Reconnect the
com uter out ut. If the LED is not green see Cause 2.
Cause 2: There is no Sync signal.
Solution: Verify the com uter out ut is o erating correctly by
connecting it directly to a monitor. If the dis lay is good,
lease call ALTINEX at [phone].
8.3 No sound
Cause 1: The source has a roblem.
Solution: Check the source and make sure that there is a signal resent
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 resent, see Cause 3.
Cause 3 Cable connections are incorrect.
Solution: Make sure that cables are ro erly 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 roblem.
Solution: Make sure the receiving device has ower and is turned on. If
there is still no sound, lease call ALTINEX at [phone].
8.4 No remote image
Cause 1: The source has a roblem.
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 roblem.
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
[phone].
