Optional product feature

The Box PC has a bus unit with a PCI slot and a shared ISA /PCI slot. Expansion
cards can be installed to ISA specification (Rev. 3.1) and PCI specification (Rev.
2.0) with a maximum length of 265mm (175 mm for shared ISA/PCI modules). All
the PCI slots can be used as masters. Only 5V PCI modules are operable.

The bus unit is executed as a purely passive module, i.e. there are only socket
contacts for the expansion cards and any necessary backup capacitors. The power
supply to the expansion cards is effected via the connection of the bus unit with the
basic board. The -5V voltage is not provided for in the power supply and is
produced from the -12V on the bus unit via in-phase voltage control.
