Antenna Connector
An external active or passive antenna can be connected to the U.FL antenna connector.
Depending on the used antenna, an U.FL to SMA adapter might be required to connect
an antenna.

Input Connector
The input connector is a 4-pin single-row interface. The PX1N provides the binary inputs
wheel tick (WT) and direction (forward signal) which are routed to the GNSS or,
optionally, to reserved pins on the PCI Express Mini Card connector. The wheel tick and
direction inputs support reliable dead reckoning functionality.
