SATA Ports
The EBX-22 provides two serial ATA (SATA) ports, which communicate at a rate of up to 1.5
gigabits per second (SATA 1). The SATA connectors at locations J8 and J10 are standard 7-pin
straight SATA connectors with friction latching. Power to SATA drives is supplied by the ATX
power supply. Note that the standard SATA drive power connector is different than the common
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.
Note
The mating connector on some SATA data cables may interfere with the proper
seating of a PC/104-Plus (PCI) expansion board at connector J17. The SATA
specification does not specify exterior dimensions for connector housings, and
some manufacturers make wider housings than others. The 3M 5602 Series straight
SATA connector is 0.22 in. wide and will interfere less with the PC/104-Plus card.
Even with thinner SATA cables, you may need to ease the cable(s) away from the
PC/104-Plus connector to seat the expansion board completely.
