The parallel interface normally runs in the standard mode SPP. The parallel
interface can be operated also in the EPP-Mode (Enhanced Parallel Port) or in
the ECP-Mode (Extended Capabilities Port) if adequate peripheral components
are available. The mode can be changed in the BIOS settings.
The devices feature two USB interfaces on the connector panel (XUSB1 and
XUSB2) and one in the device (on the carrier board).
NOTICE
The maximum power consumption of the connected device must not exceed
500 mA per USB connector. If the load exceeds 500 mA, the internal current
monitoring is activated.
