Connect the +9V AC adapter input to AC voltage and the output plug to the DA1907LX. Verify the LED in the top right corner of the unit’s front panel turns on and RED. Step 2. Connect the video output from the computer to the computer input connector on the DA1907LX using the cable provided. If a longer cable is required, make sure that the cable uses internal coaxial cables and that the cable is not excessively long. Step 3. Verify the LED on the face of the unit changes from RED to GREEN indicating an active signal is present. If the LED is not GREEN, the computer may not be sending video signals. NOTE: If using a laptop computer, the laptop may need to be set to output to the display to the external video port manually. Step 4. Connect the display devices (monitors and/or projectors) to Outputs 1 & 2 of the DA1907LX. Step 5. Verify the picture quality on both displays is good. If there is no signal, make sure that the display is compatible with the resolution of the computer graphics card. Step 6. The DA1907LX is now operational. The DA1907LX requires no adjustments for performance. Once set-up, the DA1907LX will work trouble-free without user intervention. TROUBLESHOOTING GUIDE 8 We have carefully tested and have found no problems in the supplied DA1907LX; 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 ON and GREEN when the unit is receiving power and a SYNC signal. Cause 1: There is no AC power. Solution: Verify the supplied adapter is plugged into a working AC outlet and that the outlet has power. 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 DA1907LX. Cause 3: The DA1907LX has a problem. Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1907LX 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 DA1907LX 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 a local monitor. If the display is good, call ALTINEX at (714) 990-2300. 400-0045-006 7 DISTRIBUTION AMPLIFIER 8.3 NO REMOTE IMAGE Cause 1: The source has a problem.
