Parallel-Port Interface
The PC/104-520 incorporates a parallel port that can be set to uni-/bidirectional and Enhanced Parallel
Port (EPP) modes.
9.1
Connector
The parallel port is available through the J8 connector (26 pins). To have the signals available on a stan-
dard, parallel interface connector DSUB-25, an adapter cable is required, which is offered by Kontron (KAB-
DSUB25-1, Part Number 96015-0000-00-0). The following table shows the pinout as well as necessary
connections for a DSUB-25 adapter.

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.
To find the location of the parallel port on the PC/104-520 board, please see the Appendix “Connector Lay-
out”.
