2.7 HDD Connector (CN4)
You can attach two IDE (Integrated Device Electronics) drives to the
PCN-6351’s internal controller. The PCN-6351 CPU card has an
EIDE connector, CN4.
Wire number 1 on the cable is red or blue, while the other wires are
gray. Connect one end to connector CN4 on the CPU card. Make sure
that the red (or blue) wire corresponds to pin 1 on the connector (on
the right side). See Section 2-1 for information on finding the connec-
tor.
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 the other 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 provided with your drive for more informa-
tion.
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. For more information,
please refer to any documentation provided with your drive.
See the above for connecting the second drive to CN4.
2.8 Serial Ports (CN6: COM1;
CN5: COM2/RS-232/422/485)
The PCN-6351/6351L offers two serial ports: COM1 in RS-232 and
COM2 (CN5: RS-232/422/485). These ports let you connect to serial
devices (a mouse, printers, etc.) or a communication network.
You can select the address for each port (For example, 3F8H
[COM1], 2F8H [COM2]) or disable it, by using the BIOS Advanced
Setup program.
