How it Works

CAT5 receivers over 330 feet using CAT-5 Cable. Then power the 1:8 VGA CAT5 Distri-
bution Amplifier and the receivers will get power from the CAT5. Note: VGA output 1 is
the primary connection and is used for the main display. VGA output 2 through 8 follow
the main display. The VGAdisplays attached to the 1:8 VGA CAT5 Distribution Amplifier
MUST have the same native resolution in order to get a picture.

HOW TO ADJUST THE PICTURE
7
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. The dip switches are used to set the focus and sharpness of the picture to the
best possible setting. Set the dip 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 us-
ing a different dip switch setting. The trim pod next to the VGAconnector on the 1x8 VGA
CAT5 DA R allows brightness adjustments for video.
0-25 Feet All dip switches OFF for all colors.
26-100 Feet Set dip switch #1 ON all colors. 2,3,4 remain OFF.
101-200 Feet Set dip switch #2 ON all colors. 1,3,4 remain OFF.
201-300 Feet Set dip switch #3 ON all colors. 1,2,4 remain OFF.
301 Feet and Up Set dip switch #4 ON all colors. 1,2,3 remain OFF.
NOTE: The dip switches are set to the OFF position when the switch is closest to the
number or in the down position.
