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

G or F.

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 10.

• 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.
