13Technical GlossaryCat-6a/Cat-7 Network Cabling –also called Category 6a/Category 7. This cabling is available in either solid orstranded 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 toelectromagnetic interference (EMI). FTP/STP cables include shielding the copper wires and provide betterprotection against EMI.USB 3 and USB 2.0 Cables – have two distinct full-sized connectors. The Type A connector is used to connectthe cable from a USB device to the Type A port on a computer or hub. The Type B connector is used to attach theUSB cable to a USB device.RJ45 – the Registered Jack (RJ) physical interface connects the network cabling (Cat-6a/Cat-7) to the local (Rx)and remote (Tx) extenders. You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2) forcable termination. The USB 3 Extenders require all four pairs of the cable. Note that any give cable must beterminated using the same T568 scheme on both ends to operate correctly.RJ45 Pin-OutsContacting Technical SupportIf you are experiencing problems not referenced in the Troubleshooting section, or require furtherassistance, contact Vaddio Technical Support.
