If the source offers a VGA-type 15-pin HD connector, then use a special cable - Altinex part # MS8102CA (15-pin HD Male to 5 BNC Male 6 feet cable) may be used. NOTE: You may have to use an interface (DA1910SX or VA6855WM) with your source computer to provide the appropriate signal format type and to allow the use of a local monitor. Do not use a Y-cable or monitor breakout cable to connect the computer to the DA1222AT because this will affect the quality of the high-resolution input signal. Step 4. Connect the output channels of the DA1222AT to the display devices (i.e. monitors and/or projectors) using a cable less than 10 feet with the appropriate number of channels. Step 5. Verify that the picture quality and bandwidth on all displays is good. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258-4623 or 1-714-990-2300 for international calls. The DA1222AT will operate successfully as long as cables are attached properly and other technical specifications are followed. There are no other adjustments necessary to operate the unit.

The outputs of the DA1222AT allow signals to be driven through 10 feet or more of cable depending on the cable quality and the source signal resolution. 2 What kinds of outputs are offered by the DA1222AT? The DA1222AT offers two individually buffered outputs. 3 What does buffered output mean? Buffered output means that the output signal is isolated from the input signal. The loaded output does not affect the input, or any other output on the device. A buffered output may vary in terms of the gain or peaking adjustments made to the video signal. 4 What type of signals can the DA1222AT pass? The DA1222AT can pass RGBHV, RGBS, RGsB, RsGsBs, Component Video, S-Vide, and Composite Video by using appropriate channels. Video sources may be passed through red, green, and blue channels as well as the horizontal and vertical sync channels. 5 May I use CAT-5 cables instead of coaxial cables? No, you can not use CAT-5 cables instead of coaxial cables because you will loose the quality of the video signal. Since there is no isolation of each wire, the signals will interfere with each other. 6 What is the Resolution format describes maximum the number of pixels and resolution lines in a given video image, that I can as well as the rate at which pass through each frame is re-drawn or the refreshed. Offering a DA1222AT? minimum video bandwidth of 350 MHz and a typical bandwidth close of 500 MHz, the DA1222AT allows a very high-resolution video signal to pass through without degrading the quality of the image. 7 DISTRIBUTION AMPLIFIERS TROUBLESHOOTING GUIDE 10 ALTINEX POLICY 11 • Please make sure that the amplitude of the analog video signal (RGB) is less than 1.5V. • Please make sure that the amplitude of the SYNC signal is at TTL level. • Please make sure that the proper quality of cables is used to set a perfect picture quality as your source. Before isolating any problem to the DA1222AT, make sure that all connectors are properly connected to all cables. We recommend Altinex made cables for best results. • If a problem arises after continuous usage at higher voltage, higher temperature, higher humidity, or at other extreme environmental conditions, please correct the problem. NOTE: The sync pulse voltage must be at least 1.4V for proper operation of the distribution amplifier. If lower voltage is used, please contact Altinex for additional information. • If you do not see a picture on bo...
