2.5.13 IDE2 connector (CN22)
The POD-6704 provides 2 IDE channels which you can attach up
to four Enhanced Integrated Device Electronics hard disk drives or
CDROM to the POD-6704’s internal controller. The POD-6704’s
IDE controller uses a PCI interface. This advanced IDE controller
supports faster data transfer, PID mode 3, mode 4 and UDMA/100.
The secondary channel supports UDMA/33 only.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one
of two cables (not included in this package), depending on the
drive size. 1.8" and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-
cable connector. 3.5" drives use a 1 x 44-pin to 2 x 40-pin
connector.
Wire number 1 on the cable is red or blue, and the other wires are
gray.
Connect one end of the cable to CN21 or CN22. Make sure that the
red (or blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
Wire number 1 on the cable is red or blue, and the other wires are
gray. Connect one end to connector CN21 on the CPU card. Make
sure that the red (or blue) wire corresponds to pin 1 on the
connector (on the right side). See Chapter 1 for help in finding the
connector.
Unlike floppy drives, IDE hard drives can connect in either
position on the cable. If you install two drives, you will need to set
one as the master and one as the slave. You do this by setting the
jumpers on the drives. If you use just one drive, you should set it
as the master. See the documentation that came with your drive for
more information.
Connect the first hard drive to the other end of the cable. Wire 1
on the cable should also connect to pin 1 on the hard drive
connector, which is labeled on the drive circuit board. Check the
documentation that came with the drive for more information.
Connect the second drive, as described above, on CN21.
