Compact CAT5 Audio/Video Receiver 1. Introduction 1.1 General The Model AC155A is a Receiver designed to be the counterpart for the Models AC154A-2 and AC154A-8 Splitters. It converts the CAT5 signals sent from the Splitter back to standard VGA video and audio for connection to standard VGA monitor and PC speakers. The device is housed in a compact shielded enclosure and includes a HD15 connector for the monitor, 3.
Compact CAT5 Audio/Video Receiver 2. Installation 1. At the sending end, connect the AC 154A-2 or AC154A-8 to the CPU and local monitor and keyboard per instructions given in their User’s Manual. Figure 2.1 Figure 2.2 Figure 2.3 2. Using Category-5 cable, connect the output of the Splitter to the AC155A Receiver’s UTP IN connector (see Figure 2.2) 3. Connect a monitor and powered speakers to the Receiver’s VGA and AUDIO OUT connectors. 4.
Compact CAT5 Audio/Video Receiver CAUTION Before plugging in your remote monitor, verify that the AC line is properly wired and that a protective ground (green) wire is established with NO potential difference between both the sender and Receiver locations (The UTP Splitter can tolerate up to 5 v peakto-peak ground noise between the two locations) . Failure to ensure good grounding can result in erratic operation and possible shock hazards with severe damage to your equipment.
Compact CAT5 Audio/Video Receiver 3. Configuration & Operation The only thing that requires configuration on the AC155A is the COMPENSATION switch setting. Please refer to Figure 2.2 for the location of the dip switch. The Switch has two levers. When the lever is down the switch is ON. Referring to Table 3.1 and set the dip switches according to the cable length used.
Compact CAT5 Audio/Video Receiver 4. Troubleshooting 4.1 Problem Solving FAQ 1. Fuzzy, blurry, or ghosting image at remote location If you have a stable image but it looks somewhat blurry (object or character edges are not sharp), make sure that you have set the Receiver unit’s compensation switches correctly. Also check table 3.2 to see that you have not exceeded the maximum cable length recommendation. If you still have a fuzzy image, try reducing the refresh rate and/or resolution of the PC.
Compact CAT5 Audio/Video Receiver 3. Shaking image or periodically blanking monitor Although CAT5 cable uses twisted pairs to transmit the signals from the Splitter to the Receivers to reduce the amount of EMI coupled noise from other external sources, a strong electromagnetic noise field can cause instability in the signal.
Compact CAT5 Audio/Video Receiver 6. Poor audio quality at the Receiver Only use powered speakers with the Receiver. It is also good practice to set the audio level (volume) output of the PC about 1/2 to 2/3 from the maximum and use the volume knob of the speakers to adjust the volume to the desired level. A low volume signal output from the PC reduces the signal-to-noise (S/N) ratio, whereas too high output amplitude can cause saturation and clipping to occur. 7.
