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
