Parallel Port, CN6
The parallel port is available on connector CN6. You can use Setup to select its address, associated
interrupt, and choose between its operational modes ( bidirectional and ECP).
The pinout of the connector allows a ribbon cable to directly connect it to a DB25 connector, thus
providing a standard PC compatible port.
The following tables lists the parallel port signals and explains how to connect it to a DB25 connec-
tor to obtain a PC compatible port.
NOTE!
For correct operation, keep the length of the cable connecting the cpu-
Module and parallel device less than 3 meters (10 feet).
