Chapter 2 H/W Installation
2.2.2 Connector Settings
2.2.2.1 Power Connectors (CN1, CN2, CN4, CN5)
Main power connector, +5 V, +12 V or 5V only
PCM-9388 supports ATX and AT modes.
One 4-Pin connector (CN1) supports 5 V/12 V AT power supply.
Use ATX power cable (PN: 1703200201 ATX power control cable) connect CN2; it
provides 5 VSB for ATX power.
One 2-pin connector (CN5) for power button connector.
Fan power supply connector (CN4)
Provides +5 V power supply to CPU cooling fan.
2.2.2.2 SMBus Connector
One 4 x 1 pin wafer box (CN3) supports SMBus interface.
2.2.2.3 GPIO (General Purpose Input Output) (CN6)
The board supports 8-bit GPIO through GPIO connector.
The digital inputs and outputs can be programmed as input data or output to devices,
with input or output defined. (CN6).
2.2.2.4 Audio Interface (CN7)
Audio Port Connectors
One 5 x 2-pin box header for Audio connector. These audio connectors are used for
audio devices.
2.2.2.5 IDE, CDROM Hard Drive Connector (CN8)
The board provides 1 IDE channel with which you can attach up to two Enhanced
Integrated Device Electronics hard disk drives or CDROM to the board.s internal con-
troller. Its IDE controller uses a PCI interface.
This advanced IDE controller supports faster data transfer, PIO mode 4, Multi-word
DMA mode 2 and an UltraDMA-33 interface.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. This package includes one 44-
PIN IDE cable that can connect to 1.8" and 2.5" drives.
1. Connect one end of the cable to Hard Drive connector. 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).
2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on
the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the connector).
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you
install two drives, you will need to set one as the master and one as the slave by
using jumpers on the drives. If you install only one drive, set it as the master.
2.2.2.6 Solid State Disk
The board provides a CompactFlash. card type I socket.
CompactFlash (CN9)
The CompactFlash card shares a Primary IDE channel which can be enabled/dis-
abled via the BIOS settings.
