Information on USB devices
The USB devices are detected by the "plug-and-play" function. If several devices of the same
type are connected, only the USB device that was connected first is available. Settings for
the USB devices are made in the setup. A maximum of 8 external USB devices (incl. USB
hub) can be connected if they do not exceed the maximum load of 500 mA. If overloaded,
the corresponding USB devices are automatically disabled.
Requirements with regard to an external USB hub
The USB devices are detected by the "plug-and-play" function. If several devices of the same
type are connected, only the USB device that was connected first is available. Settings for
the USB devices are made in the setup. A maximum of 8 external USB devices (incl. USB
hub) can be connected if they do not exceed the maximum load of 500 mA. If overloaded,
the corresponding USB devices are automatically disabled.
Requirements with regard to the USB stick
There is no guarantee that all manufacturers' USB sticks will function faultlessly. That is
why an industrial grade SD card is recommended to ensure the reliable recording of data.
The USB stick must be formatted to FAT or FAT32. NTFS format is not readable. The
system supports only USB sticks with max. 32 GB.
The USB stick must not be connected to the device via a USB hub. Interference from
other USB devices may result in data loss.
Requirements with regard to an external USB keyboard
The system only supports keyboards which can be addressed using generic drivers (HID
keyboard - Human Interface Device). Special keys are not supported (e.g. Windows keys).
Users can only enter characters that are available in the entry character set of the device.
All unsupported characters are rejected. It is not possible to connect a wireless keyboard.
The following keyboard layouts are supported: DE, CH, FR, USA, USA International, UK, IT.
See setting under "Setup -> Advanced setup -> System -> Keyboard layout".
Requirements for the SD card
Industrial grade SD-HC cards with max. 32 GB are supported.
Use only the industrial grade SD cards described in the "Accessories" section of the
Operating Instructions. These have been tested by the manufacturer and guaranteed
to function faultlessly in the device. → 61
