Short on Twisted Pair Cabling

Figure 7 shows a short between wires 5 and 6. The shorted
wires flash to indicate the fault. The cable length is 75.4 m.

Note

When there is a short, the far-end adapter and the
mapping of the unshorted wires are not shown.

Crossed Wires

Figure 8 shows that wires 3 and 4 are crossed. The the pin
numbers flash to indicate the fault. Cable length is
53.9 m. The cable is shielded.

Detection of crossed wires requires a far-end adapter.
