Overview 3 Overview This section describes: The VM-9T, see section 3.1 The power connect feature, see section 3.2 Using shielded twisted pair (STP) / unshielded twisted pair (UTP), see section 3.3 Recommendations for achieving the best performance, see section 3.4 3.1 About the VM-9T The Kramer VM-9T is a high quality video audio line amplifier / CAT5 transmitter. It has looping inputs with selectable video input signal termination, and distributes the signals to two identical outputs.
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.
