2.1.6 Serial ATA Interfaces
The CP-RIO3-05 provides two onboard SATA II interfaces implemented as two onboard SATA
connectors, J4 and J5, used to connect standard SATA devices via SATA cables. A SATA II
repeater is provided on the CP-RIO3-05 to improve the signal performance.
The following figure and table provide pinout information for the SATA connectors J4 and J5.
Note ...
When using a Serial ATA cable, it is recommended to use a special right-angled
Serial ATA cable due to possible space limitations within the system. For further
information, please contact Kontron.
Note ...
To ensure secure connectivity, the SATA connector supports the use of SATA II
cables (SATA cables with locking latch).
SATA II support for external SATA devices is a function of the backplane, the
SATA device and cabling. In general, the more connectors and cabling involved,
the less chance of achieving proper external SATA II device operation.
