2.9.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN1. Make sure that the
red wire corresponds to pin 1 on the connector.
2. Attach the appropriate conector at the other end of the cable to the
floppy drive(s). You can use only one connector in the set. The set
at the other end (after the twist in the cable) connects to the A:
drive. The set in the middle connects to the B: drive.
3. If you are connecting a 5¼” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
When connecting a 3½” floppy drive, you may have some difficulties
in determining which pin is number one. Look for a number on the
circuit board indicating pin number one. In addition, you should check
if the connector on the floppy drive has an extra slot. If the slot is up,
pin number one should be on the right. Please refer to any documenta-
tion that came with the drive for more information.
If needed, connect the B: drive to the connectors in the middle of the
cable as described as above.
If your cable needs to be custom made, you can find the pin assign-
ments for the board's connector in Appendix A.
2.10 Parallel port connector (CN8)
Normally, the parallel port is used to connect the card to a printer. The
PCM-3345 includes a multi-mode (ECP/EPP/SPP) parallel port. It is
accessed via CN8, a 26-pin flat-cable connector.
You will need an adapter cable if you use a traditional DB-25 connec-
tor. The adpater cable should have a 26-pin connector on one end and
a DB-25 connector on the other.
The parallel port interrupt channel is designated as IRQ7.
