Floppy-Drive Interface
The floppy-drive interface of the PC/104-520 uses a 2.88 MB super I/O floppy-disk controller and can sup-
port one floppy disk drive with densities that range from 360 kB to 2.88 MB. The controller is 100% IBM
compatible.
14.1
Connector
The floppy disk interface is available on the flat-foil connector J11 (26 pins). This type of connector is often
internally used in notebooks to connect a slim-line floppy drive.
Accessories are available for this interface from Kontron. To connect a standard 3.5” floppy drive, use an
adapter cable (ADA-FLOPPY-2, Part Number 96001-0000-00-0). If you have a slim-line 3.5” floppy drive, you
may need a flat foil cable (KAB-FLOPPY/ MOPS-1, Part Number 96019-0000-00-0). It also is possible to get a
slim line 3.5” floppy drive with cable from Kontron (FLOPPY-MOPS-1, Part Number 96010-0000-00-0).
The following table shows the connector pinout.

To protect the external power lines of peripheral devices, make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
