Different Connector’s Cable Map
4.
You can use the MT-7029 to validate the cable map on RJ11
and RJ45 connectors. The cable map function finds the most
common wiring status on twisted pair cabling: good, shorts,
opens, and crossed pairs as shown in Figure 5.
•
Good wiring:
Each LED that corresponding to an active
pin flashes briefly and in a stairway order.
•
Shorts:
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.
•
Opens:
If an LED flashes briefly, then no LEDs turn on,
that pin is open.
•
Crossed pairs:
If one LED flashes briefly, then another
LED lights for one second, the wire for the first LED is
crossed pairs to the pin for the second LED.
5.
Each LED that corresponds to an active pin flashes briefly, it
should light for about 1 second. The brief flash shows which
LED is next in the sequence.
