4.1.4.3.5 USB interfaces
The link module is equipped with a USB 2.0 (Universal Serial Bus) host controller with several USB ports, of which
2 USB interfaces are routed externally and freely available to the user.
Warning!
USB peripheral devices can be connected to the USB interfaces. Due to the variety of USB devices
available on the market, B&R cannot guarantee their functionality. The functionality of USB devices
available from B&R is ensured.
Caution!
Due to the general PC specification, this interface must be handled with the utmost care with regard
to EMC, cable routing, etc.
On AP99D systems (panels with operating elements), the USB2 interface is not available for the user. With AP99D
≤ Rev. A0, it is taken up by the RFID transponder; with AP99D ≥ Rev. A2, it is used for the front USB interface. If
the USB cable is unplugged, the RFID transponder or front USB interface is disabled.
