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 ter­minal 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.

Detailed 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.

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 r Add.

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 device­specific 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

With 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

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 non­volatile 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 Web­Based-Management, the USB-Server reverts to this default IP address until valid new parameters are assigned.
21
Subject to errors and modifications
W&T Assigning/Changing IP Parameters
3.2 DHCP mode (factory default setting)
Many networks use DHCP (Dynamic Host Configuration Protocol) for centralized and dynamic assignining of the network parameters. As shipped and after a reset to the factory default settings, DHCP mode is enabled, so that in network environments with dynamic IP assigning all you need to do is connect the device to the network. The following parameters can be assigned using DHCP:
• IP address
• Subnet mask
• Gateway address
• Lease time
1
After an unintended address assignment or address
change to an unknown address using DHCP protocol, the management tool WuTility can be used to find the USB server and uniquely identify it based on its MAC address. Changing the wrong IP address or switching to Static mode while disabling DHCP protocol can also be done using WuTility.
3.2.1 Activating DHCP mode
DHCP protocol is activated by switching from Static mode to DHCP mode using WuTility or Web-Based Management of the
USB-Server. The previous static IP address is then deleted and DHCP protocol is enabled. The USB-Server returns to its default address 190.107.233.110 until new network parameters are assigned using a DHCP server.
• Activating using the management tool WuTility
In the device list select the desired USB-Server and click on the IP Address button. In the following dialog window check
i
An explanation of the gasic terms and fundamentals of addressing in the Internet as well as DHCP and BOOTP can be found in our manual „TCP/IP­Ethernet and Web-IO““.
22
W&T Assigning/Changing IP Parameters
the radio button DHCP and then click on the Continue button.
• Activating using Web Based Management
In the menu Config r Device r Basic Settings r Network select the option Static. After entering the new IP address and the valid subnet mask and gateway address, click on the Apply button. To save the new setting in the USB-Ser­ver, select Logout and Save. The device can now be reached under the new IP address.
1
Switching from Static to DHCP mode causes the
device to revert from the static set IP address to the factory default setting 190.107.233.110. If the IP assignment using DHCP fails, for example because no DHCP server is available, the USB-Server may no longer be reachable, especially in routed network environments. Reactivating Static mode using WuTIlity can only be done using a computer in the same physical network.
3.2.2 Deactivating DHCP mode
DHCP mode is deactivated by switching from DHCP mode to Static mode using WuTility or Web-Based-Management on the
USB-Server. In both cases the new values for IP address, subnet mask and gateway address must be manually specified.
• Deactivating using the WuTility management tool
From the device list select the desired USB-Server and click on the IP Address button. In the resulting dialog window activate the Static radio button. After entering the new IP address and the valid subnet mask and gateway address click on the Continue button..
• Activating using Web Based Management
In the menu Config r Device r Basic Settings r Network activate the Static option. After entering the new IP address as well as the valid subnet mask and gateway address click
i
Each IP address must be unique within the network.

Subject to errors and modifications
W&T Assigning/Changing IP Parameters
on the Apply button. Clicking on Logout and Save saves the new setting in the USB-Server and the device can again be accessed under the new IP address.
3.2.3 System Name
To support a possible later automated updating of the DNS system using the DHCP server, the USB-Server identifies itself within the DHCP protocol by its system name. The factory default name is USBSERVER- followed by the last three places of the Ethernet address. For example the factory set system name of a USB-Server having Ethernet address 00:c0:3d:01:02:03 is USBSERVER-010203. The system name of the USB-Server can be changed using Web Based Management.
3.2.4 Lease time
The lease time determined and sent by the DHCP server specifies the time limit of the assigned IP address. After half the lease time has expired the USB-Server attempts to extend the time and update the address. If this is not possible by the time the lease time expires, for example because the DHCP server can no longer be reached, the USB-Server deletes the IP address and reverts to the factory default address
190.107.233.110. At the same time the cyclical search for alternate DHCP servers for assigning a new IP address is started.
Because the clock is absent the lease time for the current IP address is no longer available after a reset. After the restart there is then a corresponding update request with the original DHCP server. If the latter cannot be reached at this point in time, the USB-Server deletes the IP address and reverts to the factory default address 190.107.233.110. At the same time the cyclical search for alternate DHCP servers for assigning a new IP address is started.
24
W&T Assigning/Changing IP Parameters
In DHCP mode the remaining lease time in seconds together with the current IP address is displayed on the Web page Doc r Properties.
1
If after the assigned lease time has expired the DHCP
server cannot be reached, the USB-Server deletes the IP
address and reverts to the factory default address
190.107.233.110 and starts the cyclical search for alternate DHCP servers. All existing connections to W&T USB Port Redirectors are closed. To prevent problems of this kind we recommend configuring the lease time in the DHCP server to in- finite whenever possible.
3.2.5 Reserved IP addresses
The USB-Server is designed as a TCP server and therefore provides services which can be used as needed by computer­side USB Port Redirectors. In order to open a connection these need of course the current IP address of the USB-Server, so that it makes sense to reserve a particular IP address for the USB­Server on the DHCP server. This is generally done by linking the IP address to be assigned to the unique Ethernet address of the USB-Server, which can be found on the sticker on the housing.
53641 [Model] EN=00c03d004a05 OK xxxxxx
Ethernet address
3.2.6 Dynamic IP addresses
Fully dynamic address assignment, where the USB-Server gets another IP address after each restart or after expiration of the lese time, only makes sense in network environments with automatic cross-connection between the DHCP and DNS
