SATA Drive
Serial ATA (SATA) disk drives provide high-capacity, removable storage. The Vector supports a
single, 5 V, 2.5-inch form factor SATA drive on sockets

Notes:
The on-board SATA controller and Mini PCIe expansion slot share a PCIe bus from the Intel
SCH US15W through an on-board PCIe multiplexer. Therefore, these functions are
mutually exclusive. The multiplexer is software-controlled using the SMBus GPIO13 signal.
By default, SATA is enabled.
On the development kit, this default setting can be changed using the BIOS setup utility. For
details about changing the BIOS settings, see the Vector Development Kit Quick Start
(Eurotech document # 110124-7001).
USB Disk Drive
A USB disk drive can connect to any of the four USB host ports on the dual USB sockets:
and

Communications
A key capability of the Vector is its comprehensive system connectivity. It includes six USB ports, up
to two EIA-232/485 serial ports, Mini PCIe expansion slot, a Gigabit Ethernet port, two CAN 2.0B
buses, and an I
2
C bus. The following sections describe these interfaces.
Universal Serial Bus
The Universal Serial Bus (USB) ports included on the Vector support connectivity with a wide range of
available USB devices. The following table describes the six USB ports.

General-purpose USB Host
The Vector provides two general-purpose USB host ports supporting the USB 2.0 specification
operating at high (480 Mbps), full (12 Mbps), or low (1.5 Mbps) speeds. These ports provide power
management including power switch, current limiter circuit, common mode chokes, and over-current
protection allowing these ports to connect to external devices. Connect client devices such as USB
mouse, keyboard, and storage to USB Host 3 and USB Host 4 on
. The USB protocol
allows client devices to negotiate the power they need from 100 mA to 500 mA in 100 mA increments.
The Vector supplies 5 V power to these USB host ports through a power switch with over-current
detection. Make sure to account for power used through USB in your power budget.
High-current USB Host
USB Host 1 and USB Host 5 on
are designed to support higher-current, plug-in USB
modules. Similar to the two general-purpose USB host ports, these ports include on-board power
management circuitry and support the USB 2.0 specification operating at high (480 Mbps), full
(12 Mbps), or low (1.5 Mbps) speeds. However, the current rating is higher than the general-purpose
ports allowing expanded capability.
