W&T Quickstart
Step 1: Installation
The housing of the W&T USB-Server and the arrangement of the
ventilation slot is designed for installation on a standard DIN
rail per DIN EN 50022-35.
1Especially in local conditions at elevated temperatures
any alternate method of mounting must still ensure
adequate air circulation.

W&T Quickstart
Step 2: Power and network connection
Power-over-Ethernet
When PoE is used (IEEE802.3af) power for the W&T USB-Server
is provided by the network infrastructure, so that simply
connecting the network cable is all that is required.
Using an external power supply
Alternately power can be brought in externally to the screw ter-
minal located on the underneath of the device. The wide-range
input of the USB-Server allows use of DC voltage from +24 -
+48V. The input is reverse polarity protected, i.e. the polarity of
the supply voltage is not critical.

Step 4: Setting the network parameters
The default address of the W&T USB-Server is:
190.107.233.110
In addition, DHCP protocol is the factory default. If the network
in question has a DHCP server, the network basic parameters
are automatically assigned after powering up the W&T USB-Ser-
ver and after it is connected to the network.
Alternately the WuTility inventory and management tool can be
used to switch to static network parameters. Install this tool on
a Windows PC from the included product CD; the PC must be
located in the same subnet as the W&T USB-Server.
After starting, WuTility automatically searches the network for
accessible W&T network devices. Select from the list of found
devices the desired W&T USB-Server and then click on the IP
Address button.
The following dialog allows you to switch to Static mode for
manually assigning the IP address, subnet mask and gateway.
Activating Static mode automatically deactivates DHCP
protocol.
1Detailed information about the various methods of
assigning the IP address is found in the Assigning the IP
address section.

Step 5: Installing the W&T USB Port Redirector
The W&T USB Port Redirector implemented as a Windows core
driver makes a virtual USB host controller available. Install it on
a Windows XP or higher machine using the W&T product CD
included in the scope of delivery. Login as Administrator or
with administrator rights is required for installation.
After starting the W&T product CD, the link Search is located
on the USB-Server tab. In the following dialog select the 32- or
64-bit version as required by your system and then click on the
Install/Uninstall button. In addition to the actual core driver the
associated configuration and management tool is also installed
in the new program group W&T USB Port Redirector.
1To make it possible to publish updates to the W&T USB
Redirector as soon as possible, the driver is not WHQL
certified. To successfully finish the installation the
corresponding message from the Windows logo test must be
acknowledged with Continue installation.
1Detailed information about installing is found in the W&T
USB Port Redirector section.

Step 6: Connecting to a USB device
The configuration tool is started from the new program group
W&T USB Port Redirector. The local subnet is automatically
searched for by W&T USB Servers and connected USB devices.
Double-clicking on the desired device results in the following
dialog.
In addition to the three options for duration, any existing
connection can also be closed here.
•Dont’ use
Quits any existing connection to a USB device so that it can
be used by other systems.
•Until program exits
The USB device remains logged on in the system until the
configuration tool is closed.
•Until Windows is restarted
The USB device remains logged on in the system even after
the configuration tool is closed. It is not logged off until
Windows is restarted. D

14
W&T Quickstart
•Permanently
The USB device is permanently logged on in the system. This
means that after a computer restart the connection is
automatically restored and the USB device logged on in the
system.
Like when plugging in to a local USB port, clicking the OK
button adds the USB device to the WIndows plug&play system.
The device-specific driver installation than then be used as if it
were connected to a local USB port on the computer.
If the Windows computer and the W&T USB-Server are not
located in the same subnet, no automatic inventorying can take
place. The W&T USB-Server must first be manually added using
Device rAdd.

2 System Overview and Function
The W&T USB-Server together with the W&T USB Port Redirector provides a
transparent network tunnel for sending USB datagrams.
.Data connection concept
.Virtual USB-Host-Controller

16
W&T System Overview
2.1 Introduction to the W&T USB-Server
The W&T USB-Server in conjunction with the computer-side
in W&T USB Port Redirector enables the addition of remote USB
devices located in the network. With respect to the device-
specific drivers and applications these behave as if they were
connected to a local USB port on the computer.
2.1.1 Supported USB modes
The W&T USB-Server conforms with USB 1.0, 1.1 and 2.0 with
transmission speeds of 1.5 Mbit/s (Low), 12 Mbit/s (Full) and
480 Mbit/s (High). This means most USB devices using the
transfer modes Control, Interrupt and Bulk are supported.
Isochronal mode, which is used mainly in audio and video
applications, is in development.
Due to the complex interaction between operating system,
often multiple driver instances and the respective hardware, USB
applications are in practice not always plug&play. W&T
therefore offers the service of a compatibility check of your USB
device together with the W&T USB-Server. For additional
information, see our Web site at http://www.wut.de/53641.
2.1.2 Maximum number of USB devices
Although the W&T USB-Server is designed for direct connection
of two USB devices, connection of an external USB hub per USB
port is also supported. This allows max. 8 USB devices to be
connected and incorporated through the W&T USB Port
Redirector into Windows systems. It should be noted however
that multi-function devices do often already have internal hubs.

W&T System Overview
1With respect to data throughput - especially when
connecting High-Speed USB devices - it must be
remembered that only a theoretical bandwidth of maximum
100Mbis/s is available on the network side.
2.1.3 System overview
On the hardware side the W&T USB-Server adapts the USB
devices. Processing of the time-critical USB protocol takes place
locally and is mirrored - time-decoupled - on the network side
to a TCP server service.
On the software side the W&T USB Port Redirector acts as a
virtual USB host controller. When the user connects to one of
the USB devices, the latter is available to the respective system
after opening the network connection as if it were locally
connected. Connections to USB devices are always exclusive,
i.e. a simultaneous attempt from a competing USB Port
Redirector is rejected and can only take place after closing the
first connection.
In order to keep the configuration effort of the firewall in
protected environments to a minimum, the entire network
communication takes place or a single, configurable TCP port.
In parallel with this there are management services for
configuration, firmware updates etc. available which, however,
are not required for the connection between USB-Server and
USB Port Redirector.
A list of all ports used by the USB-Server can be found in the
Appendix.

3 Assigning/Changing IP Parameters
After the hardware installation of the USB-Server, the IP address and any
subnet mask and gateway for operation in a TCP/IP network must be
assigned. Please check with your systems administrator for the correct
values of these parameters. The USB-Server factory default IP address is
190.107.233.110.
.Setting the IP address, subnet mask and gateway address using the
management tool WuTility
.Setting the IP address, subnet mask and gateway address using DHCP
protocol
.Changing the IP parameters using Web-Based-Management

20
W&T Assigning/Changing IP Parameters
3.1 Managing the network parameters in the USB-Server
The W&T USB-Server distinguishes between two modes with
respect to its network-side basic parameters..
Static
IP address, subnet mask and gateway are stgored in the non-
volatile setup of the USB-Server, and DHCP protocol is disabled.
The parameters set using this method remain stored even after
power interruptions and resets until they are changed using
WuTility or Web-Based-Management.
DHCP (factory default setting)
DHCP protocol is enabled and the USB-Server attempts to
obtain its IP parameters from a DHCP server located in the
network. If no DHCP server can be accessed or the attempt to
obtain an IP address is rejected, the USB server operates using
the factory default IP address 190.107.233.110. When
switching from Static to DHCP mode using WuTility or Web-
Based-Management, the USB-Server reverts to this default IP
address until valid new parameters are assigned.
