Parallel port connector (CN11)
Normally, the parallel port is used to connect the card to a printer.
The PCM-3864/3860 includes an on-board parallel port, accessed
through CN16, a 26-pin flat-cable connector. You will need an
adapter cable if you use a traditional DB-25 connector. The cable
has a 26-pin connector on one end and a DB-25 connector on the
other.

PS/2 Keyboard connector (CN6)
The PCM-3864/3860 board provides a mini-DIN keyboard
connector which supports PS/2 keyboard. In most cases, especial-
ly in embedded applications, a keyboard is not used. The standard
PC/AT BIOS will report an error or fail during power-on self test
(POST) after a reset if the keyboard is not present. The PCM-
3864/3860 board's BIOS standard setup menu allows you to select
"All, But Keyboard" under the "Halt On" selection. This allows no-
keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).
