11. Parallel-Port Interface
The MOPSPM104 incorporates a parallel port that can be set to uni-/bidirectional and supports EPP/ECP
operating modes.
11.1 Connector
The parallel port is available through the X10 connector (32 pins). To have the signals available on a
standard, parallel interface connector DSUB-25, an adapter cable is required, which is offered by Kontron
(KAB-DSUB25-2, Part Number 61033). The following table shows the pinout as well as necessary connec-
tions for a DSUB-25 adapter.

Note:
To protect the external power lines of peripheral devices, make sure that
1
- 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 MOPSPM104 board, please see the Appendix "Connector Lay-
out".
