SPECIAL APPLICATION

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.
