Internal USB Host
USB Host 0 supports the USB 2.0 specification operating at high (480 Mbps), full (12 Mbps), or low
(1.5 Mbps) speeds; however, this port does not include power management. These USB signals route
directly from the SCH US15W to header J35 , page 36 . Use this port to connect to devices internal to
your system.
USB Client (optional USB Host)
Header J26 , page 35 supports a USB 2.0 client port. USB client devices are self-powered or can
receive power from the host computer. Since the USB cable does not power the Vector, it does not
need a power input. However, the USB input power is used to sense when a USB cable is connected.
Notes:
This port can function as an additional USB host port using an external adapter. If your
application requires a USB host port in place of the USB client port, contact your local
Eurotech sales representative for additional information.
On the development kit, the USB Client port is disabled by default and can be enabled using
the BIOS setup utility. For details about changing the BIOS settings, see the Vector
Development Kit Quick Start (Eurotech document # 110124-7001).
Serial Ports
The Vector provides one serial port on header J27 , page 35 and an optional second serial port on
header J34 , page 36 . Each serial port supports baud rates from 300 bps to 1.2 Mbps. By default,
these ports are configured as 5-wire, EIA-232 serial ports. As an alternate configuration, each serial
port can operate in EIA-485 mode. This configuration requires software support for EIA-485 mode
including control of the SMBus GPIO signals, GPIO00 and GPIO03, which select the mode of
operation.
The serial port enable is also software-controlled using the SMBus GPIO04. This signal enables or
disables both serial ports. For details about these control signals, see System Management I/O ,
page 21 .
Notes:
The on-board touch panel controller and second serial port share a serial interface;
therefore, these functions are mutually exclusive. Selection of the function is set at time of
production. In the default configuration, the touch panel controller is selected and header
J34 is not populated.
On the development kit, Serial Port 1 is disabled by default and can be enabled using the
BIOS setup utility. The mode of operation for the serial port can also be changed using this
utility. For details about changing the BIOS settings, see the Vector Development Kit Quick
Start (Eurotech document # 110124-7001).
Mini PCIe Expansion Slot
The Vector provides a Mini PCI Express (PCIe) expansion slot on J33 , page 36 , supporting off-the-
shelf, third-party peripherals. This expansion slot includes a PCIe x 1 bus, USB host port, SMBus,
control signals, and LED indicators.
Notes:
The Mini PCIe expansion slot and on-board SATA controller 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.
In the default setting, SATA is enabled and the PCIe bus is not available on J33. However,
the USB host port and SMBus are available for use supporting USB-only cards.
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).
