Connection Example
UTP Cable Testing
The UTP cable test function can be used to check straight
and crossover network cables for shorts and open circuits.
What Information Is Displayed?
The ‘
UTP CABLE TEST
’ screen shows the termination of each
wire of the CAT5 at both ends of the network cable.
The fi rst column shows the 8 terminations in order from 1 to
8 in the end of the cable which is plugged into the LCD330.
The second column shows the corresponding terminations at
the opposite end of the network cable.
If a termination in the second column displays a ‘
0
’ there may
be an open circuit in that specifi c wire.
If two terminations
show ‘0’
they may both be open circuits or they could be
short circuiting to each other
The tables below show the correct terminations for both
types of network cable.
