4-Port XGA Video Splitter 1. Introduction 1.1 General The Model AC090A is a 1 in x 4 out XGA Video Splitter / Distribution Amplifier with field-programmable cable length compensation on 2 outputs for driving long video cables. The unit accepts a VGA input signal from a computer and provides 2 standard outputs and 2 boosted outputs. The standard outputs are labeled "STD" and are capable of driving cables up to approximately 150 feet.
4-Port XGA Video Splitter 2. Installation 1. Connect the COMPUTER input connector on the AC090A to the computer's video (or any other compatible video source) using the supplied cable (see figures 2.1). The video connector on the PC is usually a HD15 female with three rows of contacts. XGA Splitter Outputs 1 and 2 (DX) Can Drive Long Cables Figure 2.1 Figure 2.
4-Port XGA Video Splitter 2. Connect the AC adapter to the PWR jack on the splitter and plug it in the AC source. Connect up to 4 monitors to the outputs of the splitter. If any of the monitors are to be located further than 150 feet, plug them in to the DX ports of the splitter (see figure 2.2). 3. The Model AC090A has a special compensation to drive long video cables that can be applied to outputs 1 & 2. Use the following table to set the dip-switch for these outputs (see figure 2.3).
4-Port XGA Video Splitter 4. If you are using cables longer than 25 feet on any of the outputs of the splitter, make sure that the cable is connected to a monitor for proper termination, or else disconnect the cable from the splitter.
4-Port XGA Video Splitter 3. Operation The video signal is fully terminated and buffered in the AC090A. The splitter should operate optimally with no special attention or procedure. Assuming that there are no major grounding or large EMI noise problems present in the installation location, the video quality at the remote stations depend on the quality and the length of the video cables used. In addition, the resolution and refresh rate settings of the computer affect image clarity.
4-Port XGA Video Splitter 4. Troubleshooting 4.1 Problem Solving FAQ 1) Fuzzy, blurry, or ghosting image at remote location If you have a stable but somewhat blurry image (object or character edges are not sharp), make sure that you have set the unit’s compensation switches correctly. If you still have a fuzzy image, try reducing the refresh rate and/or resolution of the PC. You should also be sure to use multi-coaxial (double shielded) 75 ohm video extension cables for best results.
4-Port XGA Video Splitter either connect a monitor to this output port, or disable the plug-and-play monitor detection in the PC’s operating system. 4) Faint shadows or ghosts at the monitors If you are using cables longer than 25 feet on any of the outputs of the splitter, make sure that the cable is connected to a monitor for proper termination, or else disconnect the cable from the splitter. 5) Substituting power supplies The splitter relies on the AC power adapter that is supplied with it.
