pin number one should be on the right. Please refer to any documenta-
tion that came with the drive for more information.
If your cable needs to be custom made, you can find the pin assign-

2.15 CompactFlash™ socket (CN16)
The PCM-3350 is equipped with a CompactFlash™ Type I disk socket
on the solder side, which supports the IDE interface CompactFlash
disk card. The socket itself is specially designed to prevent any
incorrect installation of the CompactFlash disk card. When installing
or removing the CompactFlash disk card, please make sure that the
system power is off.
The CompactFlash™ disk card is defaulted as the E disk drive in your
PC system. To fit the EMAC CFC into the PCM-3350, simply plug
it into the designated connector. It will only fit when the red triangle on
the CFC is aligned with the triangle on the connector. The card will not
fit any other way (do NOT use excessive force).
2.16 USB connector (CN17)
The PCM-3350F board provides two USB (Universal Serial Bus)
interfaces, which give complete plug and play and also hot
attach/detach for up to 127 external devices. The USB interfaces
comply with USB specification rev. 1.0 and are fuse protected.
The USB interfaces are accessed through a 8-pin flat-cable connector,
CN17. The adapter cable has a 8-pin connector on one end and a USB
connector on the bracket.
The USB interfaces can be disabled in the system BIOS setup.
