Compact CAT5 Audio/Video Splitter 1. Introduction 1.1 General The Models AC154A-2 and AC154A-8 are respectively 2 and 8channel UTP (CAT5) VGA video splitters (senders) with audio. The devices convert a PC's VGA and audio signals into a format that can be transmitted using a single inexpensive and commonly available Category-5 Unshielded Twisted Pair (UTP) cable with RJ45 connectors, which are used in most Local Area Networks.
Compact CAT5 Audio/Video Splitter 2. Installation 1. Connect the VGA IN and AUDIO IN connectors of the AC154A to the computer's video and speaker ports using the supplied cables (see figures 2.1 and 2.2). Figure 2.1 Figure 2.2 2. Figure 2.3 Connect the local monitor and speakers to the device's VGA OUT and AUDIO OUT connectors respectively. (see Figure 2.3) NOTE To expand the number of outputs, use these ports to daisy chain to another AC154A’s VGA and audio inputs.
Compact CAT5 Audio/Video Splitter 4. Using Category-5 cable connect one or more AC155A receivers to the unit's RJ45 outputs. The outputs are labeled PORT A and PORT B on the AC154A-2 or OUT 1 through OUT 8 on AC0154A-8. 5. Connect the remote monitor and speakers to the receiver unit and attach the power adapter to the receiver. Please refer to AC155A User’s Manual for further details.
Compact CAT5 Audio/Video Splitter 3. Operation The video signal is fully terminated and buffered for the local video output connector. This means that terminating or plugging a local monitor is not necessary and this connector can be left open. The stereo audio input is passed through to the local audio output connector and the audio integrity is fully preserved. The transmitted audio in the CAT5 cable to the remote receiver is monaural. The audio outputs are “line-level” and powered speakers are required.
Compact CAT5 Audio/Video Splitter 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 3.1 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 Splitter 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 Splitter 6. Poor audio quality at the receiving end Only use powered speakers with the splitter and receivers. 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.
