3.4 Parallel port connector (CN19)

Normally, the parallel port is used to connect to a printer. The SOM-
DB4400 includes a multi-mode (ECP/EPP/SPP) parallel port,
accessed through 25-pin DB-25 connector.
You will need an adapter cable if you use a traditional DB-25
connector. The adpater cable should have a 26-pin connector on
one end and a 25-DB connector on the other.
The parallel port is designated as LPT1 and can be disabled.
