5. AC universal switching power supply 3 2 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 CATS cable for longer distances heavy gauge cable should be used For a CATS cable exceeding a distance of 50 meters separate power supplies should be connected to the transmitter and to the receiver simultaneously The power connect feature applies to the VM 9T The VM 9T can power for example the 712N receiver see the example illustrated in Figure 3 However the 712N cannot power the VM 9T 1 CATS cable is still suitable for the video audio transmission but not for feeding the power at these distances 3 Overview 3 3 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 c
