SATA Ports (J1, J7)
The VL-EBX-37 provides two serial ATA (SATA) ports, which communicate at a rate of up to
3.0 gigabits per second. The SATA connectors at location J1 and J7 are standard 7-pin straight
SATA friction latching connectors.
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.
USB (Multiple Connectors)
The VL-EBX-37 includes eight USB channels. There are six USB ports with standard USB Type
A connectors, located on the baseboard at locations J2, J3, J4, J8, J9, and J10. The eUSB
connector at J27 and PCIe Mini Card connector at J14 each provide one USB channel. These
connectors are protected against ESD damage.
The USB interface on the VL-EBX-37 is UHCI (Universal Host Controller Interface) and EHCI
(Enhance Host Controller Interface) compatible, which provides a common industry
software/hardware interface.
