Parallel-Communication Interface; Connector - Kontron MOPS/386A User Manual

PARALLEL-COMMUNICATION INTERFACE

9.
The MOPS/386A incorporates an IBM XT/AT compatible parallel port. It can be set to bi-
directional and supports SPP, EPP and ECP operating modes. The bi-directional functions
are compatible with those of an IBM PS/2 style parallel port.

Connector

9.1
The parallel port is available through the X7 connector (26 pins). To have the signals
available on a standard, parallel-interface connector DSUB-25, an adapter cable is
required, which is available from 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.
