WIRING AND DISPLAY EXAMPLES

Properly Wired T568A UTP:

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. Mixing “A” and “B” creates a cross-over cable.

T568A Cable with a miswire and unrecognized continuity:

1 and

2 pins on the

VDV Scout

Pro 2

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 neither a short or open. An ID remote connected to the

VDV Scout

Pro 2

when in cable test mode would also show this error.

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 Split Pairs:

A common error in building a cable is to put all the pairs in pin sequence 1-2, 3-4, 5-6 and 7-8. This will

produce the correct continuity, but the pairs are designated to be on pins 3-6 and 4-5 in the middle of the connector for compatibility with

phone wiring. This wiring error is only detected by the split pair test since the designated pairs are not twisted together.
