38 CMX58886CX cpuModule BDM-610000050 Rev A
multiPort Configured as a Parallel Port
The parallel port is available on connector CN6. Make sure the multiPort in the BIOS Setup is configured to
parallel port. You can use the BIOS Setup to select the parallel port’s address and associated interrupt, and
choose between its operational modes (SPP, ECP, EPP 1.7, and EPP 1.9).
The pinout of the connector enables a ribbon cable to be connected directly to a DB-25 connector, thus
providing a standard PC compatible port.
Table23 lists the parallel port signals and explains how to connec t it to a DB-25 connector to obtain a PC
compatible port.
Note For correct operation, keep the length of the cable connecting the cpuModule and parallel device
less than 3 meters (10 feet).
