The
WireMaster Mapper
is equipped with the necessary adaptors
and Remotes to test cables with BNC, F, and RJ11/RJ45 connec-
tors. It also includes Clip Lead adapters to allow any pair of wires
to be tested. Additionally, almost any off-the-shelf BNC adaptor
can be used with the
WireMaster Mapper.
They are often avail-
able through electronic supply houses or Do It Yourself outlets.
Using these adaptors, the BNC connectors on the
WireMaster
Mapper
can be adapted to most coaxial connectors (TNC, SMA,
RCA Phono, 1/8" and 1/4" phone jack, PL-259, etc.)
If a low resistance ground or return path is available at both the
Remote location and at the
WireMaster Mapper
location, single
wires can be ID’ed. Connect one alligator clip at both locations to
the ground. Connect the other clip to the wire(s) to be ID’ed. ID
the wires at the
WireMaster Mapper
by connecting the remaining
alligator clip to each wire and noting the displayed ID.
Note:
If the ground or return path has too much resistance, or has
AC or DC current flowing in it, incorrect ID’s may be obtained.
Mapping Cables through a Splitter
The
WireMaster Mapper
will map individual Remotes through a
fully power passive splitter. Most splitters, like those used in CATV
(Cable Television) are
not
power passive. Some splitters are not
power passive through all of their ports (partially passive). Satel-
lite splitters and high quality splitters are often power passive, but
