8.10 USB Interface
All Provit 5000 system units are equipped with a USB Host controller with two USB ports:
Because of general PC specifications this interface should be handled with extreme
care with regard to EMC, location of cables etc.
8.11 AT Keyboard Connection (PS/2)
A PS/2 socket is used to connect an external AT enhanced keyboard. The external AT keyboard
works parallel to connected Panelware keyboards. The keyboard interface is operated by the
MTC (see the section "AT PS/2 Keyboard"). An external PS/2 AT keyboard is available from B&R
(see Chapter 7 "Accessories").
These settings cannot be changed.
