Parallel Port Interface
14. Parallel-Port Interface
The coolMONSTER/PM incorporates an IBM XT/AT compatible parallel
port. It supports uni-directional, bi-directional, EPP and ECP
operating modes.
14.1 Connector
The parallel port is available through connector X11 (26 pins).
To have the signals available on a standard, parallel-interface
connector
DSUB-25,
an
adapter
available from KONTRON (KAB-DSUB25-1, Part Number 96015-0000-00-
0).
The
following
table
shows
the
connections for a DSUB-25 adapter.

Notes: (
*)
To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of
-- IEC/EN 60950.
