INSTALLATION INSTRUCTIONS

HOW TO ADJUST THE PICTURE

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 (Dual Inline Package) switches are used to set the focus and sharp-

ness 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 using a different DIP switch setting. The trim pot next to the VGA

connector on the VGA RS232 Extender-R allows brightness adjustments for video.

0-25 Feet All DIP switches are set to OFF for all colors.

26-100 Feet Set DIP switch #1 ON for all colors. 2,3,4 remain OFF.

101-200 Feet Set DIP switch #2 ON for all colors. 1,3,4 remain OFF.

201-300 Feet Set DIP switch #3 ON for all colors. 1,2,4 remain OFF.

301 Feet and Up Set DIP switch #4 ON for 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.

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.
