Compact CAT5 Audio/Video Splitter

1. Introduction

1.1 General

The Models AC154A-2andAC154A-8are respectively 2 and 8- channel 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 availableCategory-5Unshielded Twisted Pair (UTP) cable with RJ45 connectors, which are used in most Local Area Networks.

At the receiving (remote) end a matching receiver (Model AC155A – sold separately) is used to convert the UTP signal back to VGA and audio.

The devices are housed in compact shielded enclosures and include connectors for the local monitor and speakers as well as multiple RJ45 connectors for connection to remote monitors.

Included with the devices are: a small power adapter, and short video and audio cables for connection to the PC’s VGA and sound card’s outputs.

The RJ45 outputs can drive CAT5 LAN cables to 500 feet (152 meters) with little to no degradation of video quality. A proprietary circuit in the receiver is used to compensate for signal losses in long cable runs.

1.2Features

Buffered video and pass-throughaudio outputs for connection to local monitor and speakers

Support resolutions up to 1280x1024 at any refresh rate

Rugged, Reliable, Compact size

No software required

Drive standard CAT5 cables to 500 feet

Transmit audio and video signals on one cable

Easily expandable by daisy-chainingthe local in/out ports

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

Figure 2.3

2.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. Connect the local monitor and speakers to the last unit in the chain.

3.Connect the supplied power adapter to the power input connector on the unit.

4.Using Category-5cable connect one or more AC155A receivers to the unit's RJ45 outputs. The outputs are labeled PORT A and PORT B on theAC154A-2or OUT 1 through OUT 8 onAC0154A-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.

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 peak- to-peakground 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. If an LCD is being used at the remote location, verify that the LCD ground is tied topower-lineground. If not, then ground the receiver unit by adding a ground strap (see troubleshooting section for more information).

NOTICE

Do not connect this unit to any LAN device such as network cards or hubs as this may damage the AC155A and/or the LAN device. Use EIA/TIA 568B standard straight-throughpatch wiring as shown below. Do not use crossover cables.

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.

Assuming that there are no major grounding or large EMI noise problems present, the video quality at the remote station depends on the length of the CAT5 cable, actual video resolution and refresh rate.

The Model AC155A receiver employs proprietary user settable video compensation to enhance the image quality when long cables are used.

In general at low and mid resolutions excellent image reproduction is provided at up to 500 feet. At high resolution and refresh rates perfect image reproduction can be achieved at shorter distances (see table 3.1 below). Using longer cables or higher resolution rates will still produce an image, but the reproduction quality will be reduced.
