Compact CAT5 Audio/Video Splitter and Receiver
7
3.2 Receiver
Several receiver types are available (URA-x). All Receivers have a single
COMPENSATION potentiometer (pot) adjustment to recover high frequency
signal loss for long runs of the cable.
The Model URA-X2 has 2 identical VGA outputs and 2 Audio outputs. It acts as
if a standard URA was followed by a video and audio splitter.
The URA-VOL provides volume level adjustment (section 3.2.1).
3.2.1
Adjusting the video quality for long cable runs
Please refer to Figure 2.4 for the location of the compensation pot. Turning the
pot CW increases the compensation. Use a small screwdriver and starting from
CCW slowly turn the pot CW until the image is perfectly clear. Fully CCW
corresponds to no compensation (recommended for lengths of 100 ft or less),
and fully CW corresponds to 1000 feet. Be careful not to over-compensate the
video image.
The video quality at the remote station depends on: (1) the length of the CAT5
cable, (2) video resolution setting, and (3) refresh rate setting.
In general, at low and mid resolutions, excellent image reproduction is provided
at up to 1000 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.
