Kramer Electronics TP-305A Manuale Utente

Overview 

4 

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. 

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 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
