CHAPTER 2
PRODUCT FEATURES
2.1 Description
The Wire Mapper Pro is a hand-held structured cable tester and trouble-
shooterdesignedforuseonUTP,STP,FTP&SSTPcablingequippedwith
RJ45 connectors and wired to either TIA 568A/B (ISO11801 & EN50137),
USOCorISDNspecications.Itdetectsopencircuitpairs,shorts,crossed
wires, crossed pairs, reversed pairs, shield faults and split pairs.
In the event of opens and shorts, the Wire Mapper Pro uses TDR technology
to indicate if the fault is at the near end of the cable, the remote end, or if it is
somewhere in between. It will then indicate the distance to the fault.
The Wire Mapper Pro has the ability to measure and indicate the length of the
cable under test, using a Vp (Velocity of Propagation), set by the user. It will
measure and report the length of all 4 pairs of wires in the cable under test. It
also generates an audible tone that is transmitted into all 4 pairs on the cable
undertest.Thiscanbeusedforcabletracingandidentication.
This instrument also has the ability to identify telephone and data lines. If the
main unit is plugged into an operational RJ45 socket, it will give a continuous
warning tone and appropriate display if a telephone voltage is present on any
of the pins. If the Service Detect key is pressed, it will give a display distin-
guishing 10base-T, Token Ring and 100Mbit+ connections.

Hand-held cable and troubleshooting tester

TIA568 STP TIA568 UTP ISDN USOC UTP USOC STP
NOTE: For testing of wiremap in accordance with ISO11801 & EN50137
theproductshouldbesettoTIA568whichistheequivalentstandard.
For FTP and SSTP cables use the STP setting.
•Vpisselectableintherange20%to100%.
(see § 4.3 if the Vp is not known)
•TheWireMapperPromaybesettomeasurecablelengthinfeetormeters.
•TheinstrumentmaybesettooperateinEnglish(USAorUK),French,

•ThedisplaycontrastmaybesetbyselectingContrast and then press-
ing the

•Toexitsetupmode,pressthebutton.
4.3 Determining and Measuring Vp Values
Vp, or Velocity of Propagation, values are characteristic of each cable
type and brand. The Vp is used to measure the length of a cable and to
measure a fault location. The more accurate the Vp, the more accurate the
measurement result will be.
ThecablemanufacturermaylisttheVpontheirspecicationsheetor
may be able to provide it when asked. Sometimes this value is not readily
available,ortheusermaywishtodetermineitspecicallytocompensate
forcablebatchvariations,orforspecialcableapplications.Thisisquite
easy:
1. Take a cable sample of exact length increments (ft or m) longer than
60ft (20m).
2. Measure the exact length of the cable using a tape measure.
3. Connect one end of the cable to the Wire Mapper Pro (see § 4.11).
Leave the end un-terminated and make sure the wires do not short to
each other.
4.
Measure the length and adjust the Vp until the exact length is displayed.
5. When the exact length is displayed, Vp is established.

Notice the word FAILED under the cable ID1 and also the detailed mes-
sage at the bottom of the display.
The graphical portion of the display also shows that the fault is an open on
pin 7 at the remote end by showing a break in the line at this point.
NOTE: In the event that an open or short circuit fault occurs at
either end of a cable or link under test, the unit will show the fault
as at the near end or the remote end. These faults are the most
common and are mainly due to termination problems.
If the fault occurs some way along the cable or link under test,
then a display similar to the one shown below will occur. Notice,
that on this occasion the actual measured distance to the fault
is given.
In the event of a Short fault, the following is displayed:

is a short between pins 1 and 2 and the short is drawn at an approximation
to the distance along the cable or link under test, at which it occurs.

LENGTH / Vp
The remote unit does not need to be attached for this
test to be performed. Although it does not matter if it
is attached, any terminators on ISDN wiring or sockets
should be switched out of the circuit or disconnected.
Attach the main unit to one end of the cable and press the
LENGTH / Vp
button.
The length of all four pairs in the cable are measured, and the results dis-
played simultaneously, as shown below.
Pr. 4-5 64ft
Pr. 1-2 64ft
Pr. 3-6 -----
Pr. 7-8 64ft
TIA568 UTP Vp=71%
In this example, the length of pair 3 - 6 is missing, as there is a fault on the
pair which is preventing the TDR circuit from measuring the length.
Length will be displayed in the selected units, either meters or feet, and
the Vp and cable testing standard will also be displayed. Length measure-
ment accuracy depends on the correct setting of the Vp (Velocity of Propa-
gation) for the cable under test.
If the Vp is not known for a particular cable, then a known length of that
cable (at least 60ft or 20m long) may be connected to the instrument and
the Vp adjusted until the correct length reading is obtained (see § 4.3).
