The Wire Mapper Pro™ Model CA7028
is a hand-held structured cable mapping
and troubleshooting tester designed
for use on UTP, STP, FTP and SSTP
cabling equipped with RJ-45 connectors
and wired to either TIA 568A/B (ISO
11801 and EN 50137), USOC or ISDN
specifications. It detects open circuit
pairs, shorts, crossed wires, crossed
pairs, reversed pairs, split pairs and
shield faults.
In the event of opens and shorts, the
Model CA7028 uses TDR technology
to indicate if the fault is at the near
end or the remote end of the cable,

or if it is somewhere in between. It will
then indicate the distance to the fault.
The Model CA7028 has the ability to
measure and indicate the length of the
cable under test, using a Vp (Velocity
of Propagation) set by the user, from
a built-in library or manually. It will
measure and report the length of all
four pairs of wires in the cable under
test. It also generates an audible tone
that is transmitted into all four pairs on
the cable under test. This can be used
for cable tracing and identification in
conjunction with a tone generator.

The Model CA7028 also has the ability
to identify telephone and data lines.
If the main unit is plugged into an
operational RJ-45 socket, it will give a
continuous warning tone and display if
a telephone voltage is present on any
of the pins. If the Service Detect key
is pressed, it will check and display
telephone, 10BaseT, 100Mbit+ and
token ring active service
