Connecting The Floppy Drive - Aaeon MB-668 Manual

Quick Installation Guide
Floppy drive connector (CN7), FPC (CN9)
You can attach up to two floppy drives to the mainboard controller.
You can use any combination of 5¼" (360 KB and 1.2 MB) and/or
3½" (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy chain drive connector cable for (CN7) 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 con-
nectors. Each set consists of a 34-pin flat-cable connector (usually
used for 3½" drives) and a printed-circuit board connector (usually
used for 5¼" drives). Plus an additional Flexible Printed Circuit
(FPC) connector (CN9), extra drive means extra memory for your
system. An ideal way for cost effective design.
Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray.

Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into CN7. Make sure that
the red or blue wire corresponds to pin 1 on the connector. No wor-
ries for CN9 FPC connector, it's guided design for error free con-
nection.
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. 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 connec-
tor.
If you are connecting a 3½" floppy drive, you may have trouble
determining which pin is pin number 1. Look for a number printed
on the circuit board indicating pin number 1. Also, the connector
on the floppy drive connector may have a slot. When the slot is up,
pin number 1 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.
