USB Interface

The USB interface comes with two USB ports which follow the OHCI/EHCI specification and are USB 2.0
compliant. You can expand the amount of USB connections by adding external hubs.

Connector

The USB ports are available through the X15006 and X15007 connectors (each 4 pins). To have the signals
available on the standard USB interface connectors an adapter cable is required. An USB interface cable is
