INTRODUCTION

Congratulations on your purchase of the VGA CAT-5 1:8 Distribution S.

Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies.

Gefen’s reliable, plug-and-play products supplement cross-platform computer systems, professional audio/video environments and HDTV systems of all sizes with hard-working solutions that are easy to implement and simple to operate.

The Gefen VGA CAT-5 1:8 Distribution S

The VGA CAT-5 1:8 Distribution S is the perfect solution for sending highdefinition video from a single VGA source to as many as eight remotely located

VGA displays. The system is capable of delivering resolutions up to 1920x1200 as far as 330 feet away from the source over industry standard CAT-5 cabling.

How It Works

Connect the VGA video source to the input of the VGA CAT-5 1:8 Distribution S with the included VGA cable. The Sender and each Receiver (not included with

Sender unit) are then connected by individual runs of CAT-5 of up to 330 feet in length. The Receiver units (sold separately) receive the video signal and DC power from the Sender over the CAT-5, and are connected to the displays with user supplied VGA cables. Power up the Sender with the included power supply, and you now have crisp, high-resolution video at your remote displays.

Please note that all of the VGA displays used must have the same native resolution in order to get a picture.

DIP SWITCH CONFIGURATION

Using DIP Switches to Compensate for Video Issues

The first step in adjusting the video quality is to display text and a graphic on your monitor (i.e. desktop icons). Then set your computer to the resolution that you will be using most frequently. Set the DIP (Dual Inline Package) switches to the settings that are recommended for the different lengths of CAT5 cable (see chart below). Verify that the picture quality is to your satisfaction. If the recommended setting does not produce a great quality picture, try using a different DIP switch setting.

The three DIP switch banks affect the primary colors Red, Green and Blue directly and are thus labelled accordingly. Should you find a problem with too much or too little or a certain color present in the output video, begin adjustments in the DIP switch bank corresponding to the color that is present/absent too much.

The settings shown below are our recommendations for best performance.

0-25 Feet

26-100 Feet

101-200 Feet

201-300 Feet

301 Feet and Up

All DIP switches are set to OFF for all colors.

Set DIP switch #1 ON for all colors. 2,3,4 remain OFF.

Set DIP switch #2 ON for all colors. 1,3,4 remain OFF.

Set DIP switch #3 ON for all colors. 1,2,4 remain OFF.

Set DIP switch #4 ON for all colors. 1,2,3,remain OFF.

NOTE: A DIP switch is set to the OFF position when the switch is closest to the number printed immediately below it. The word “ON” will be printed at the top of the

DIP switch bank, usually in the lefthand upper corner.

NOTE: The default position of the DIP switches is that of the 26-100 feet setting

above with DIP Switch #1 ON for all colors and switches 2,3,4 OFF.
