ABOUT YOUR DA1930CT

DA1930CT

VGA + AUDIO TO CAT-5

TRANSMITTER

2

The DA1930CT provides a means of transmitting computer video and audio signals over twisted pair

(CAT-5) type cable when used together with an

ALTINEX Twisted Pair Video Receiver, such as the DA1931CT.

The DA1930CT is compact and easy to use. The

DA1930CT is able to transmit any one of the video sources, such as VGA, Component Video, S-video or C-Video and Stereo Audio over the CAT-5/6 cable to the DA1931CT or equivalent receiver.

The DA1930CT provides Audio Loop output and buffered VGA Output for a Local Monitor connection. The DA1930CT offers a female 15-pin

HD input with the native Plug & Play compatibility,

4 pin Mini-Din connector for S-Video and RCA connector for Composite Video Input. The 3.5mm

Stereo Audio Jack with Loop Through is used for

Audio Input. The 15-pin HD Female connector is used for local monitor output. The three female RJ-

45 main outputs are providing distributed drive to three Twisted Pair cables. Unit also offers hardware audio volume control and Video

Equalization for up to 400 feet. There is also a signal detect feature which shows when a signal is present.

INSTALLING YOUR DA1930CT 6

Step 1. Plug the 9V power adapter into an AC outlet and then connect the other end to the POWER input jack on the DA1930CT.

Step 2. Verify the LED near the top of the unit is illuminated RED indicating power is applied.

Step 3. Connect the video output from the local computer to one of the video inputs, either

RGBHV/YPbPr or S-Video or Composite

Video.

Step 4. Verify the power LED at the top of the unit changes to GREEN, indicating a SYNC signal has been detected.

Step 5. Connect the stereo audio output from the local computer to the AUDIO input on the

DA1930CT.

Step 6. Connect the local monitor to the LOCAL

OUTPUT video connector labeled

RGBHV/YPbPr on the DA1930CT.

Step 7. If using external speakers on the local device, connect the local audio speaker inputs to the LOCAL OUTPUT labeled

AUDIO on the DA1930CT.

Step 8. Connect a CAT-5 cable to one of the

4TP OUTPUT connectors on the

DA1930CT. The other end of the cable should be connected to a DA1931CT

Receiver, and the receiver should be connected to a monitor device and audio device.

Step 9. Verify the picture quality on the receiving monitor is equivalent to the quality as displayed on the local monitor. If the quality of the image is poor or non-existent, it may be necessary to adjust the Video Equalization on the

DA1930CT and/or DA1931CT. See the

OPERATION section that follows for details.

OPERATION 7

The DA1930CT requires only two adjustments to be made for optimal performance. The first is Video

Equalization for long cable lengths. The second is

Audio Gain for volume control of the main (CAT-5) output,

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 DA1930CT and DA1931CT 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.

7.2 AUDIO GAIN

Normally, the AUDIO GAIN control on the

DA1930CT will be set to maximum. When set to maximum, the transmitted volume will be equivalent to the volume from the audio source.

If necessary, the transmitted volume may be reduced as required by the user.

TROUBLESHOOTING GUIDE 8

We have carefully tested and have found no problems in the supplied DA1930CT. 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

DA1930CT.

Solution: Verify the DC power plug coming from the AC adapter is plugged all the way into the DA1930CT.

Cause 3: The DA1930 has a problem.

Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1930CT 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

DA1930CT 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 the local 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 DA1930CT. 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.

8.5 REMOTE IMAGE 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 DA1930CT. 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.
