3.1 About the Power
Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, needs to be connected to a power source when the
devices are within 90m ( 270ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
90m on standard TP cable. For longer distances, use heavy gauge cable (TP
cable is still suitable for the video/audio transmission, but not for feeding the power
at these distances).
3.2 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5 / CAT 6 / CAT 7a cables.
