Fdd Connector (Cn23) (Optional); Connecting The Floppy Drive - Advantech AIMB-330F User Manual

2.9 FDD connector (CN23) (optional)

You can attach up to one floppy disk to the AIMB-330F's on-board con-
troller. You can use any combination of 5.25" (360 KB and 1.2 MB) and/
or 3.5" (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy-chain drive connector cable is required for a dual-drive
system. On one end of the cable is a 34-pin flat-cable connector. On the
other end are two sets of floppy disk drive connectors. Each set consists
of a 34-pin flat-cable connector (usually used for 3.5" drives) and a
printed-circuit board connector (usually used for 5.25" drives).

2.9.1 Connecting the floppy drive

Use FDD cable connector with CN23 on the AIMB-330F
1. Plug the 34-pin flat-cable connector into CN23 connector. Make
sure that the red wire corresponds to pin one on the connector.
2. Attach the appropriate connector on the other end of the cable to
the floppy drive(s). You can use only one connector in the set. The
set on the end (after the twist in the cable) connects to the A: drive.
3. If you are connecting a 5.25" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connec-
tor. If you are connecting a 3.5" floppy drive, you may have trouble
determining which pin is pin number one. Look for a number
printed on the circuit board indicating pin number one. Also, the
connector on the floppy drive connector may have a slot. When the
slot is up, pin number one should be on the right. Check the docu-
mentation that came with the drive for more information. The B:
drive can be attached to the connectors in the middle of the cable as
described above.
