Kramer TP-112HD [5/13] About the power connect feature

Overview

3 Overview

This section describes:

• The power connect feature, see section 3.1

• Using shielded twisted pair (STP)/unshielded twisted pair (UTP), see

section 3.2

• A summary of the TP-112HD, see section 3.3

• Recommendations for achieving the best performance, see section 3.4

3.1 About the Power Connect™ Feature

The

Power Connect feature applies as long as the cable can carry power.

This feature is available when using STP cable and the distance does not

exceed 50m on standard CAT 5 cable. For longer distances, heavy gauge

cable should be used

. For units which are connected via RJ-45 connectors,

make sure that the shield of the STP cable is connected to the metal casing

of the connectors on both ends of the cable. For units which are connected

via terminal block connectors, the shield of the STP cable must be

connected to a ground terminal on the units at both ends (use the ground

terminal of the power supply connection if necessary).

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)

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 non-skew-free cable, Kramer

BC-STP is intended for analog signals where skewing is not an issue. For

cases where there is skewing, our UTP skew-free cable, Kramer BC-XTP,

may be used. Bear in mind, though, that we advise using STP cables where

possible, since the compliance to electromagnetic interference was tested

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 might cause inconformity to

electromagnetic standards, Kramer does not commit to meeting the standard

with UTP cable.

1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
