3.2 Controlling via the RC-108 and RC-116 Presentation Controllers
The RC-108 and RC-116 are presentation controllers designed specifically to
control a BoardView™ system 1 . Each presentation controller has the
appropriate number of input selector buttons 2
3.3 Shielded Twisted Pair (STP)/Unshielded Twisted Pair (UTP)
, an RS-485 and 12V DC port
and an RS-232 9-pin D-sub port for firmware upgrade.
We recommend that you use Shielded Twisted Pair (STP) cable, and stress
that the compliance to electromagnetic interference was tested using 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.
In cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-
free cable, Kramer BC-XTP, may be advantageous, and UTP cable might
also be preferable for long range applications. In any event when using UTP
cable, it is advisable to ensure that the cable is installed far away from
electric cables, motors and so on, which are prone to create electrical
interference.
3.4 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 3
For a CAT 5 cable exceeding a distance of 50m, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
. 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).
1 Up to eight and up to 16 units, respectively
2 Eight and 16 buttons, respectively
3 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
