Technical Glossary
Category 5e/6/7 (CAT 5e/6/7) Network Cabling
Category 5e/6/7 cable is commonly also referred to as CAT 5e/6/7. This cabling is available in either solid or
stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP (Shielded Twisted
Pair). UTP cables are not surrounded by any shielding making them more susceptible to Electromagnetic
Interference (EMI). STP cables include shielding the copper wires and provides better protection against
Electromagnetic Interference (EMI).
USB 2.0 Cables
USB 2.0 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 5e/6/7) 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 USB 2.0 Ranger 2304GE-LAN requires all four pairs of the cable. RJ45 connectors are
sometimes also referred to as 8P8C connectors. Note that any given cable must be terminated using the
same T568 scheme on both ends to operate correctly.
