Adjusting the CAT5•4000 Extender Using an Analog (VGA) Source
The CAT5•4000 was designed for plug-and-play installation. However,
differences in CAT-5 cabling quality and skew rates may require the user to
adjust the brightness and focus of the resulting video output. If the output video
is too blurry/sharp or dark/bright please use the instructions below to adjust the
output quality.
1. Locate the Brightness (Br) and Focus (Fo) Trim Pots on the front panel of
the CAT5•4000 receiver.
2. Insert a small fl at-head tool into the desired Trim Pot receptacle.
3. Turn the Trim Pot in either a clockwise or counter-clockwise motion until the
desired adjustment level is reached. The Trim Pot has a limited range in
both directions. Please do not force the Trim Pot beyond the point at which it
stops turning as this may break the Trim Pot.
4. Remove the adjustment tool from the Trim Pot receptacle.
