Validating RJ11 and RJ45 Cable Maps

You can use the IT200 or IT100 toner and IT200 probe to
validate the cable map on RJ11 and RJ45 connectors. The
cable map function finds the most common wiring faults
on twisted pair cabling: shorts, opens, and crossed pairs.
1. Connect an IT200 or IT100 toner to a RJ11 or RJ45
jack, as shown in Figure 1.
2. Turn the toner's rotary switch to
3. If necessary, use the IP200 probe to locate the correct
connector at the other end of the cabling, as
described in the previous section.
4. Connect the IP200 probe to the RJ11 or RJ45 jack;
then turn the probe's rotary switch to CABLE MAP.
5. The probe's LEDs and beeper indicate the cable map,
as follows:
•
The number of each LED corresponds to a pin on
the connector. You can enable the SYNC LED to
validate the shield. See "Validating the Cable's
Shield" on page 12.

•
Each LED that corresponding to an active pin
flashes briefly, then should light for about 1
second. The brief flash shows which LED is next
in the sequence.
•
The probe also beeps in different tones to
indicate good wiring, miswires, shorts, and
opens.
•
Miswire: If one LED flashes briefly, then another
LED lights for one second, the wire for the first
LED is miswired to the pin for the second LED.
•
Short: If two LEDs turn on for 1 second at the
same time, those two pins are shorted together.
If more than 2 wires are shorted together, the
LEDs for the shorted pins indicate opens.
•
Open: If an LED flashes briefly, then no LEDs turn
on, that pin is open.
