20 PCM-5862 User‘s Manual
Parallel port connector (CN19)
Normally, the parallel port is used to connect the card to a printer.
The PCM-5862 includes a multi-mode (ECP/EPP/SPP) parallel
port, accessed through CN19, 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.
Keyboard and PS/2 mouse connector (CN15)
The PCM-5862 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. 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-
5862'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).
Front panel connector (CN7)
Next, you may want to install external switches to monitor and
control the PCM-5862. These features are optional —install them
only if you need them. The front panel connector (CN7) is an 8-pin
male, dual in-line header and provides connections for a speaker,
hard disk access indicator, watchdog output and an input switch
for resetting the card.
