ABOUT YOUR DA1957CT

DA1957CT

1-In, 4-Out Twisted Pair Distribution

Amplifier

2

The DA1957CT is a 1-In, 4-Out Twisted Pair distribution amplifier designed to connect a single

ALTINEX Twisted Pair transmitter to as many as 4

ALTINEX Twisted Pair receivers. The DA1957CT will pass computer video and audio signals from the transmitter over Twisted Pair-type (CAT-5) cable.

A typical setup allows a single computer's video and audio sources to be connected to as many as

4 Twisted Pair receivers. In turn, each receiver connects to a video monitor, projector etc. and/or an audio device such as a speaker or amplifier.

ALTINEX compatible transmitters and receivers include the DA1930CT Video+Audio Twisted Pair

Transmitter and the DA1931CT Video+Audio

Twisted Pair Receiver.

The DA1957CT is capable of equalizing the attenuation effects of very long cable runs depending upon the type and quality of cable being used. Additionally, there is a Signal Detect feature which shows when an input signal is present.

The latest generation of Twisted Pair devices uses an innovative, patented technology* developed by

ALTINEX. The new signal processing technology allows transmitting and receiving fully equalized computer video signals, stereo, and audio signals over long distances.

INSTALLING YOUR DA1957CT 6

Step 1. Determine the best location for the

DA1957CT.

There is an equalization adjustment on the DA1957CT that will affect all the distributed signals.

Therefore, place the DA1957CT as equidistant to all receivers as possible.

Step 2. Connect the power adapter to the

DA1957CT and plug it into the power outlet. The power indicator LED on the front panel will light red. This indicates that the unit is operational.

Step 3. Connect a cable from the Twisted Pair transmitter to the Input connector on the

DA1957CT. The LED should turn green indicating a signal is present.

Step 4. Connect 1 to 4 of the DA1957CT outputs to Twisted Pair receivers. The unused outputs (if any) do not need to be terminated.

Step 5. Connect the receiving devices (monitors, projectors, speaker, etc.) to Twisted Pair receivers per the instructions found in their manuals.

Step 6. Adjust the equalization setting for the best image quality. This normally requires 2 people; one at the transmitter and one at the receiver to adjust the receiver and view the image.

OPERATION 7

The DA1957CT will operate successfully as long as cables are attached properly and other technical specifications are followed. The only adjustment on the DA1957CT is for video equalization and only needs to be made at the time of installation.

Video equalization is provided to fine-tune the displayed image on the remote display. The equalization knob is a single-turn adjustment. At minimum (fully CCW), the arrow points to the 7 o'clock position and at maximum (fully CW) it points to the 5 o'clock position.

TROUBLESHOOTING GUIDE 8

We have carefully tested the supplied DA1957CT unit and have found no problems; however, we would like to offer the following suggestions:

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: There is no AC power.

Solution: Verify the adapter is plugged into a working AC outlet, and that the outlet has power. Only use the

ALTINEX-provided power adapter.

Cause 2: The adapter is not connected.

Solution: Verify the DC power plug coming from the AC adapter is plugged all the way into the DA1957CT.

Cause 3: The DA1957CT has a problem.

Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1957CT or the power adapter may require service, call ALTINEX at (714) 990-2300.

8 400-0377-004

DISTRIBUTION AMPLIFIERS

8.2 LED IS NOT GREEN

Cause 1: There is no power.

Solution: Disconnect the video input from the

DA1957CT 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 1: Verify the computer output is operating correctly by connecting it directly to a local monitor. If the display is good, see Solution 2.

Solution 2: Verify that the transmitter and receiver are each operating correctly by connecting them directly to each other, bypassing the DA1957CT. If the display is good, see Solution 3.

Solution 3: Reconnect the DA1957CT. If the

Power/Signal Present LED is on and red with a signal, 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 on the transmitter 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 is bad.

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 is required.

Solution: Adjust the Video Equalization on the

DA1957CT. Long cable runs may require adjustment. In general, cable runs less then 50 ft (15 m) require little or no video equalization and should be set to minimum. If there is still no image, see Cause 3.

Cause 3: There is no signal.

Solution: If the Power/Signal Present LED is on and green and there is still no image, call ALTINEX

(714) 990-2300.

8.5 REMOTE IMAGE QUALITY IS POOR

Cause 1: The source has a problem.

Solution: Check the image on a local monitor and verify the quality is good. If the local image is good, see Cause 2.

Cause 2: Video equalization is required.

Solution: Adjust the Video Equalization on the

DA1957CT. If the image is still not correct, call ALTINEX at

(714) 990-2300.
