Technical Glossary
Category 6a/7 (CAT 6/7) Network Cabling
Category 6a/7 cable is commonly also referred to as CAT 6a or CAT 7. This cabling is available in either solid or
stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair), FTP (Foiled Twisted Pair) or
STP (Shielded Twisted Pair). UTP cables are not surrounded by any shielding making them more susceptible
to Electromagnetic Interference (EMI). FTP/STP cables include shielding the copper wires and provide better
protection against EMI.
USB 3 and USB 2.0 Cable
s
USB cables have two distinct full-sized connectors. The Type A connector is used to connect the cable from a
USB device to the Type A port on a computer or hub. The Type B connector is used to attach the USB cable to
a USB device.
RJ45
The Registered Jack (RJ) physical interface is what connects the network cabling (CAT 6a/7) to the LEX
and REX units. You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2) for cable
termination as the Raven 3104 Pro requires all four pairs of the cable. RJ45 connectors are sometimes also
referred to as 8P8C connectors. Note that any give cable must be terminated using the same T568 scheme
on both ends to operate correctly.
