The vibra is connected to the engine PWB through springs attached to the Vibra motor body – X2100 and
X2101 are hard gold plated contact pads on the PWB.
System connector
The system connector provides a fully differential 4–wire stereo line-level output connection and a fully
differential 2-wire mono line-level or microphone level input connection.
The handsfree driver in N2200 is meant for the headset.
The output is driven in a fully differential mode. In the fully differential mode, the handsfree pin is the
negative output and the HFCM pin is the positive output. The gain of the handsfree driver in the differential
mode is 6 dB.
The earpiece and headset signals are multiplexed so that the outputs cannot be used simultaneously.
