INSTALLING YOUR DA1907SX | 6 |
Step 1. Connect the 9V 500mA AC adapter’s output plug to the DA1907SX’s power input connector - 2.5 mm DC Jack. Verify the LED in the top right corner of the unit on the front panel turn on and RED.
Step 2. Remove the protective port covers. Connect the video output from the computer to the computer input connector on the DA1907SX using the provided input VGA cable. If a longer cable is required, please make sure that the cable has video signals through coaxial cables and this cable is not excessively long.
Step 3. Verify the LED on the face of the unit has changes from RED to GREEN, indicating an active source is applied. If the LED is not green, the computer may not be
sending video signals. Check your Computer’s manual if you are using a laptop computer. You may have to send a command that instructs the laptop to output to the internal display and the external video port simultaneously.
Step 4. Connect your display device (monitor or projector) to the Main output. If needed, connect a monitor to the Local Monitor output port.
Step 5. Verify the picture quality on all displays 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.
OPERATION | 7 |
There are no adjustments necessary to operate the DA1907SX, the unit will operate successfully as long as cables are attached properly and other technical specifications are followed.
The DA1907SX offers a special LED on the front panel that provides feedback to the user. When power is connected to the DA1907SX, the LED will turn RED. The LED will turn GREEN when an active computer source is connected. This indicates that it is receiving a proper signal by sensing the presence of the sync portion of that signal.
TROUBLESHOOTING8
We have carefully tested and have found no problems in the supplied DA1907SX; 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 Altinex supplied adapter is plugged into a working AC outlet and that the outlet has power.
Cause 2: Adapter is not plugged.
Solution: Verify the DC power plug coming from the AC adapter is plugged all the way into the DA1907SX.
Cause 3: The DA1907SX has a problem.
Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1907SX or the power adapter may require service. Call ALTINEX at (714)
