3.1 About the Power Connect Feature

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 via the cable connecting between the

transmitter/receiver. The Power Connect feature applies as long as the cable

can carry power. The distance does not exceed 50 meters on standard CAT5

cable, for longer distances, heavy gauge cable should be used

For a CAT5 cable exceeding a distance of 50 meters, separate power supplies

should be connected to the transmitter and to the receiver simultaneously.

3.2 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 is used. 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 not apparent).
For long range applications, unshielded twisted pair (UTP) cable is preferred.

However, the unshielded twisted pair (UTP) cable should be installed far

away from electric cables, motors and so on, which are prone to create

electrical interference.

3.3 Recommendations for Achieving the Best Performance

Achieving the best performance means:

Connecting only good quality connection cables, thus avoiding

interference, deterioration in signal quality due to poor matching, and

elevated noise levels (often associated with low quality cables)

Avoiding interference from neighboring electrical appliances that may

adversely influence signal quality, and positioning your Kramer
