8.3 Limitations
The contacts for USB devices are protected and suitable to supply USB devices with a maximum input
current of 500mA. Do not supply external USB devices with higher power dissipation through these pins.
8.4 USB Client Interface
The connector J1900 provides the client interface. You need the client functionality for changing the
bootloader or update a corrupted bootloader. Together with the recovery pin (see chapter 'Crisis Mana-
gement') and dedicated software on a desktop computer as well as a standard USB cable (both ends with
Type-A connector) and a special KONTRON USB adapter cable (KAB-USB-2, part number 96054-0000-00-2)
the upload is easy.
