Parallel Port Connector (Cn21, Cn22); Keyboard And Ps/2 Mouse Connector (Cn10) - Advantech PCM-9550F User Manual

2.11 Parallel port connector (CN21, CN22)

Normally, the parallel port is used to connect the card to a printer.
The PCM-9550F/FM/L includes a multi-mode (ECP/EPP/SPP)
parallel port accessed via CN21 or CN22, and a 26-pin flat-cable
connector. You will need an adapter cable if you use a traditional
DB-25 connector. The adapter cable has a 26-pin connector on
one end, and a DB-25 connector on the other.
The parallel port is designated as LPT1, and can be disabled or
changed to LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
2.12 Keyboard and PS/2 mouse connector
(CN10)
The PCM-9550F/FM/L board provides a keyboard connector that
supports both a keyboard and a PS/2 style mouse. In most cases,
especially in embedded applications, a keyboard is not used. If the
keyboard is not present, the standard PC/AT BIOS will report an
error or fail during power-on self-test (POST) after a reset. The
PCM-9550F/FM/L'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.
