TP cable termination
Figure 13 details the recommended termination of TP cables with RJ-45 connectors in
accordance with the TIA/EIA T 568A or TIA/EIA T 568B wiring standards. You can use either
standard, but ensure that you use the same standard on both cable ends.
ATTENTION: Damage may occur to the unit if TP cables are miswired as crossover
cables.

NOTES:
• Enhanced Skew-Free AV cable is not recommended for Ethernet/LAN
applications.
• This cable is specially designed for compatibility with Extron Twisted Pair products,
wired using the TIA/EIA 568 A standard.
• The green, brown, and blue pairs of this cable have virtually identical lengths and
should be used to transmit the video signals.
• The orange pair of this cable has a different length and should not be used to
transmit the video signals.

T658A T568B T568B T568B
A cable that is wired as T568A at one end and
T568B at the other (Tx and Rx pairs reversed)
is a “crossover” cable.
A cable wired the same at both ends is called
a “straight-through” cable, because no
pin/pair assignments are swapped.
