If you are connecting a 3.5” floppy drive, you may have trouble determin- ing which pin is number one. Look for a number printed on the circuit board indicating pin number one. In addition, the connector on the floppy drive may have a slot. When the slot is up, pin number one should be on the right. Check the documentation that came with the drive for more information.

If you desire, connect the B: drive to the connectors in the middle of the cable as described above.

In case you need to make your own cable, you can find the pin assign- ments for the board’s connector in Appendix C.

2.11 Parallel port connector (CN15)

Normally, the parallel port is used to connect the card to a printer. The PCM-9575 includes a multi-mode (ECP/EPP/SPP) parallel port accessed via CN15 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 (CN25)

The PCM-9575 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-9575’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.

2.13Power & HDD LED, Reset Button Connector (CN13, CN22)

Next, you may want to install external switches to monitor and control the PCM-9575. These features are optional: install them only if you need
