Properly Wired T568A Data Cable
T568B is electrically identical to
T568A, but swaps the green
and orange pairs. Either standard
will work as long as the same
standard is used at both ends of a
run or patch cable. Mising standards
A and B creates a cross-over cable.
In the event of a cross-over, the
“X-over” icon will display and
mismatched pins will flash in the
wire map.
T568A Data Cable with Split Pairs
A common error in building a
A common error in building a cable
is to put all the wires in pin sequence -
1-2, 3-4, 5-6, 7-8. This will produce
correct continuity, but the pairs are
designated to be on pins 3-6 and 4-5
in the middle of the connector for
compatibility purposes. As the
designated wire pairs are not
matched according to wiring standards,
The “Split” error will appear. The
mismatched pins will flash in the wire
map of the LCD screen.
T568A Cable with a Short and
an Open
The 1-2 pair pins are shorted
together and the 7-8 pair is
open. The pins with the errors
are flashing. Dash lines (-) on
the bottom (remote) display line
indicate the short, while no
numbers on the bottom line
indicate the open pair.
T568A Cable with a miswire
and unrecognized continuity
1and 2 pins on the main tester are
connected to pins 2 and 1 at the
remote-end. The pins with this
error are flashing. The “U” for
the remote pin numbers
indicates an unrecognizable
continuity was detected that is
nether a short or open. An ID
remote connected to the Tester
when in cable test mode would
also have shown this error.
