Network Testing with the FrameScope Pro 2
N2620A User’s Guide 81
WireMap Adapter Operation
When the WireMap Adapter is connected to the FrameScope
Pro, the FrameScope Pro will send a sequence of DC, TTL level
signals via the wire pairs in the order of a few hundred
milliseconds. For each signalling sequence step, the receiver of
the FrameScope Pro measures the DC voltage. The FrameScope
Pro software identifies WireMap information based on the
readings.
LED indicators
The WireMap Adapter has four LEDs, each connected to a wire
pair. During the test, the LEDs flash. Once the test is completed,
the LEDs turn off.
Procedure for WireMap Testing
1 Connect the FrameScope Pro and the cable-under-test to the
WireMap Adapter.
2 Press Tools on the Main Menu screen and select WireMap.
3 Press Start Test.
