Mass Storage Interfaces
SATA
The EPM-19 provides a 1.5 Gbit/s SATA port. Power to the SATA drive is usually provided by
the ATX power supply. Note that the standard SATA drive power connector is different from
the typical 4-pin Molex connector used on IDE drives. Most current ATX power supplies
provide SATA connectors, and many SATA drives provide both types of power connectors. If
the power supply you are using does not provide SATA connectors, adapters are available.
Integrator’s Note:
Only one SATA port is available on the Vortex86DX2 chip, so only the J10 SATA port or the J2
mSATA port can be used; both cannot be used at the same time. Whenever J2 has an mSATA
card installed, the mSATA card uses the single SATA port.
