Connect one end of the power adapter cable to the DA1804NT and the other to the power outlet. The Power/Signal Present LED on the side panel should be on and red indicating the unit is operational. Step 2. Connect a coaxial cable from the video source (VCR, Document Camera, etc.) to the input connector of the DA1804NT. If the video source providing a video image, the Power/Signal Present LED on the DA1804NT should turn from red to green indicating a valid signal is present. Step 3. Connect the output connectors of the DA1804NT to the display devices (monitors or projectors) using coaxial cables. Step 4. The images on the outputs of the DA1804NT should be equivalent to the input source signal. Step 5. Installation is complete. There are no further connections or settings required. OPERATION 7 The DA1804NT requires no adjustments for performance. Once set up, the DA1804NT will work trouble-free without user intervention as long as cables are attached properly and other technical specifications are followed. We have carefully tested and found no problems in the supplied DA1804NT; however, we would like to offer suggestions for the following: 8.1 POWER LED IS NOT ON The Power/Signal Present LED should be on and red when power is applied with no input signal. Cause 1: There is no AC power. Solution: Only use the external adapter supplied with the DA1804NT. Verify the adapter is plugged into a working AC outlet and that the outlet has power. Cause 2: The adapter is not plugged into the DA1804NT. Solution: Verify the DC power plug coming from the AC adapter is plugged all the way into the DA1804NT. Cause 3: The FPI100HR has a problem. Solution: If there is AC power to the adapter and the LED still does not turn on, the DA1804NT or the power adapter may require service. Please call ALTINEX at (714) 990-2300. 8.2 LED IS NOT GREEN The Power/Signal Present LED should be on and red when power is applied, but then turn green when receiving a video signal. Cause 1: There is no power. Solution: If 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 the local monitor. If the display is good, call ALTINEX at (714) 990-2300. 400-0004-004 6 DISTRIBUTION AMPLIFIERS 8.3 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: Cable connections are incorrect. Solution: Make sure that cables are connected properly. Also, make sure that the continuity and wiring are good. If there is still no image, call ALTINEX at (714) 990-2300. 8.4 REMOTE IMAGE QUALITY IS POOR 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 Poor signal transmission. Solution: Check the cables for continuity and make sure that connections are wired properly to verify that there is good signal transmission. We recommend ALTINEX-made cables for best results. If the image is still not correct, call ALTINEX at (714) 990-2300.
