Using the Wiremap Adapter and Remote ID Locators
Terminating twisted pair cabling with the standard
wiremap adapter or optional remote ID locators lets the
tester detect all types of wiremap faults. Without this
termination, the tester cannot detect crossed wires or
crossed pairs. For a wire pair with one wire open,
termination is required to detect which wire is open.
Without termination, the tester shows both wires as open.
Using multiple remote ID locators helps you identify
connections at patch panels. The tester shows the number
of the locator connected to the far end of the cabling, as
shown on page 23.
To connect a remote ID locator to a modular (RJ) jack in a
confined area or to a 4-pin modular jack (RJ11), use the
optional universal adapter and a patch cord, as shown in
Figure 4.

Crossed Pairs
Figure 9 shows that pairs 1,2 and 3,6 are crossed. The pin

Split Pair
Figure 10 shows a split pair on 3,6 and 4,5. The split pair
flashes to indicate the fault. The cable length is 75.4 m.
In a split pair, continuity from end to end is correct, but is
made with wires from different pairs. Split pairs cause
excessive crosstalk that interferes with network operation.
Note
Cables with untwisted pairs, such as telephone
cords, typically show split pairs due to excessive
crosstalk.

Connecting to Telephone Networks Wired in Star Topologies
Telephone cables wired in a star topology (Figure 16) are
connected together at a bridge tap at the distribution
center. The bridge tap connects each wire to all other wires
of the same number.
The tester detects bridge taps and measures the distance to
the bridge tap. To measure the length of each cable
connected to the bridge tap, connect the wiremap adapter
or remote ID locator to the bridge tap and the tester to the
wall outlet.
The tester cannot measure length past the bridge tap
because reflections from the bridge tap connections
interfere with measurements.
If you connect the tester to the bridge tap, the tester
measures the length only to the bridge tap, which is only
the patch cord length.
WCaution
Do not use multiple far end adapters in star or
bus topologies. Doing so causes incorrect
wiremap results.

Connecting to Telephone Networks Wired in Bus Topologies
Telephone cables wired in a bus topology (Figure 17)
connect the wall outlets in series. In this topology, you
measure the length from the last outlet to the wiremap
adapter.
If you connect to an outlet in the middle of the series, the
tester reports a bridge tap. The length reported is the
length to the outlet, which is the patch cord length. The
tester cannot measure length past the outlet because
reflections from the cables on either side interfere with
measurements.
If you are unsure which outlet is the last in the bus, do the
following:
1
Connect the wiremap adapter or ID locator to the
beginning of the bus at the distribution center.
2
Connect the tester to an outlet and run the twisted pair
cable test.
If the tester reports a bridge tap, move to another
outlet. The last outlet will not show a bridge tap, and
will show the length to the distribution center.
WCaution
Do not use multiple far end adapters in star or
bus topologies. Doing so causes incorrect
wiremap results.

Using the Toner
You can use the tester with an optional tone probe to
locate cables in bundles, at patch panels, or behind walls.
Use the tester’s IntelliTone
Networks IP100 or IP200 tone probe. The digital IntelliTone
signal is easier to detect at a distance than analog tones,
and its frequency and encoding eliminate cable
misidentification due to signal bleed and radiated or
ambient noise.
The tester’s analog tone mode is compatible with most tone
probes.
The analog tone mode features the SmartTone
for positive identification of cables in bundles.

Calibrating Length Measurements
The tester uses an NVP value (nominal velocity of
propagation) and the signal delay through the cable to
calculate length. The tester’s default NVP values are usually
accurate enough to verify length; however, you can
increase the accuracy of length measurements by adjusting
the NVP to a specified or actual value.
The default NVP values are 70 % for twisted pair cable and
82 % for coaxial cable.
Note
NVP values can vary among cable types, lots, and
manufacturers. In most cases, these differences are
minor and may be disregarded.
Setting the NVP to a Specified Value
To enter the NVP value specified by the manufacturer:
1
Turn on the tester while holding down the Y and E
keys.
2
To set the NVP for the coaxial port (T), press Y.
3
Use E and D to set the NVP value.
4
To save the setting and exit NVP mode, turn the tester
off then on again.
Determining a Cable’s Actual NVP
You can determine a cable’s actual NVP by adjusting the
measured length to match a known length of cable.
To determine a cable’s NVP:
1
Turn on the tester while holding down the Y and E
keys.
2
To set the NVP for the coaxial port (T), press Y.
3
Connect a known length of the cable to be tested to the
tester’s twisted pair or coaxial connector.
38
Maintenance
Notes
The cable must be at least 49 ft (15 m) long. If the
cable is too short, “---” appears for the length.
For the best accuracy, use a cable between 49 ft
(15 m) and 98 ft (30 m) long.
The cable must not be connected to anything.
4
To switch between meters and feet, press M.
5
Use E and D to change the NVP until the measured
length matches the actual length of the cable.
6
To save the setting and exit NVP mode, turn the tester
off then on again.
