P/N: 2900 – 9999991 A1
ADDENDUM: Included with user manuals for machines with a CAT5 connector
This addendum describes the Power Connect feature used with Kramer
machines, and the choice between STP and UTP CAT5 cables.
Power Connect Feature
1
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter to either the transmitter or the receiver. The
other unit is fed over the same CAT5 cable.
The Power Connect feature applies as long as the CAT5 cable is heavy gauge
cable (that is, it can carry power). The distance does not exceed 50 meters on
standard cable.
For a distance of 100 meters, separate power supplies must be connected to the
transmitter and to the receiver simultaneously, unless using heavy gauge CAT5
cable.
Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded twisted
pair (STP) cable will give better results. However, the shield itself does create a
capacitance that degrades the frequency response of the machines. For shorter
distances, of 50m or so, shielded twisted pair (STP) cable is preferred because it
provides protection from interference (degradation is non-apparent).
For a long range application, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away
from electric cables, motors etc., which are prone to create electrical interference.
1 This section of the addendum is only relevant to machines that support this feature (for example, the TP-104; not the
TP-100)
