INSTALLING YOUR DA1921SX

6

Step 1. Connect the 9V 500mA AC adapter’s output plug to the DA1921SX’s power input connector - 2.5 mm DC Jack. Verify that the RED power LED turns ON.

Step 2. Remove the protective port covers. Connect the video output from the DA1920SX to the input connector on the DA1921SX using the CAT-5 cable.

Step 3. Verify that the red LED on the face of the unit has now turned green, indicating an active source. If the LED is not green, the DA1920SX may not be sending video signals.

Step 4. Connect one or two monitors (as needed) to the output connectors using the appropriate VGA cable.

Step 5. Verify that the picture quality on Monitors 1 and 2 (connected to Output 1 and Output 2 of the DA1921SX) is good. If you are not receiving a signal, make sure that the display is compatible with the resolution of the computer graphics card. Note: High levels of static discharge under some conditions may shutdown the unit. To reset the unit simply, disconnect the input cable and reconnect it back.

OPERATION

7

There is only one adjustment necessary to operate the DA1921SX. The adjustment is for equalization on long cable runs. It is adjustable according to the cable length. The unit will operate successfully as long as cables are attached properly and other technical specifications are followed.

7.1 LED INDICATOR

The DA1921SX offers a special LED on the front panel that provides feedback to the user. When power is connected to the DA1921SX, the LED will turn Red. When a valid CAT5 source is connected to the DA1921SX, the LED will turn Green, indicating that it is receiving a signal by sensing the presence of the sync portion of the signal.

7.2 EQUALIZATION

The DA1921SX provides an equalization adjustment for long cable runs. Cable runs less than 50 feet in length will require little to no equalization. After that, the longer the cable, the more equalization is required.

In some cases, it will be necessary to adjust the equalization on both the transmitter and receiver.

TROUBLESHOOTING GUIDE

8

We have carefully tested and have found no problems in the supplied DA1921SX. 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 DA1921SX.

Solution: Verify the DC power plug coming from the AC adapter is plugged all the way into the DA1921SX.
