Kramer Electronics VP-300T - Manual (Page 8)

Overview
5
For a CAT 5 cable exceeding a distance of 50m, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
We recommend that you use shielded twisted pair (STP) cable. There are
different levels of STP cable available, and we advise you to use the best
quality STP cable that you can afford. Our STP skew-free cable, Kramer
BC-SXTP, is intended for transmitting VGA signals. Our non-skew-free
cable, Kramer BC-STP, is intended for digital signals.
The compliance to electromagnetic interference was tested using STP
cables, therefore we recommend using those cables.
Although unshielded twisted pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable may not conform to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
3.3 Recommendations for Achieving the Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching,
and elevated noise- levels (often associated with low quality
cables)
Avoid interference from neighboring electrical appliances and
position your Kramer machines away from moisture, excessive
sunlight and dust
