1 General Information
• Product 1
• Documentation 3
• Support and Service 4
• Your Safety 4
• First Steps 5
1.1 Product
Purpose
UTN servers comprise USB Deviceservers and USB Dongleservers. As USB Deviceservers they make non-network-
ready USB devices (e.g. USB hard disk drives, USB printers, etc.) and as USB Dongleservers non-network-ready USB
dongles accessible via TCP/IP network. For this purpose, the USB devices respectively USB dongles will be con-
nected to the USB ports of the UTN server. Then the UTN (UTN = USB to Network) functionality and the corre-
sponding software tool 'SEH UTN Manager' establish a virtual USB connection between USB device respectively
USB dongle and client. The USB device respectively USB dongle can be used as if it were connected locally.
System Requirements
The UTN server has been designed for the use in TCP/IP networks.
The SEH UTN Manager runs on the following systems:
• Windows XP or later except for Windows Vista and Windows Server 2008
(For Windows 7 and Windows Server 2008 R2 KB3033929 http://technet.microsoft.com/en-us/library/security/3033929 must be in-
stalled.)
• OS X 10.8.x, OS X 10.9.x, OS X 10.10.x, OS X 10.11.2 and later, macOS 10.12.x and later
(OS X 10.11.2 and later: operating system induced limited USB device support. macOS 10.12.x and later: operating system induced lim-
ited USB device support.)
• Linux: *.deb (for Debian-based systems) and *.rpm (for Red Hat-based systems) installation packages are avail-
able for 64-bit systems. A successful installation cannot be guaranteed due to the multitude of Linux varieties!
The installation must be carried out on your own.
In the following 64-bit systems the installation was tested successfully:
Debian: Debian 8.10, Debian 9, Ubuntu 14.04, Ubuntu 16.04
Red Hat: CentOS 6.9, CentOS 7.4, Fedora 25, Fedora 26, openSUSE Leap 42.3, Oracle 6.9, Oracle 7.4, Red Hat
Enterprise Linux 7.4, SUSE Linux Enterprise 12.3
• IPv4 TCP/IP network
Important:
The Dongleservers myUTN-80 and myUTN-800 are exclusively designed for the de-
ployment of USB dongles.
Important:
Hereinafter USB dongles and USB devices are referred to as 'USB devices'.

myUTN User Manual Linux General Information
This document describes the usage in Linux environments. Information about the usage in other environments
can be found in the relevant system-specific User Manual. More details can be found in chapter ’Documentation’
3.
Combination with Associated Products
You can combine the UTN server with additional SEH Computertechnik GmbH products to ideally adapt the use
of your devices to your environment!
Serviceplus
For the Dongleservers myUTN-80 and myUTN-800 service contracts, the Serviceplus packages, are available. The
Serviceplus package extends the manufacturer's guarantee of a Dongleserver from 36 to 60 months. In addition,
you will receive quickly and easily an advance replacement device in case of a defect. Serviceplus packages must
be purchased separately.
Detailed information:
https://www.seh-technology.com/services/service-packages.html
Rack Mount Kits
For a perfect and safe storage of your Dongleserver we recommend the 'Rack Mount Kits' (RMK). With the instal-
lation kits, you can install the Dongleservers in 19" server racks.
Detailed information:
https://www.seh-technology.com/products/rack-mount-kits.html
Important:
The support of isochronous USB devices (e.g. cameras, microphones, speakers, etc.)
depends on
• the operating system:
- Windows
- Linux
• the UTN server model
(information can be found in the respective product information)
• the software version:
- firmware/software for UTN servers: 14.5.5 or later
- SEH UTN Manager: 3.1.4 or later

2.2 Administration via the SEH UTN Manager
The 'SEH UTN Manager' is a software tool developed by SEH Computertechnik GmbH. The SEH UTN Manager is
used to establish and manage connections to the USB devices connected to the UTN servers.
• Features 8
• Versions 9
• Installation 10
• Program Start 13
Features
The software is installed on all clients that are meant to access a USB device in the network. After the SEH UTN
Manager is started, the network is scanned for connected UTN servers. All UTN servers found and their connected
USB devices are displayed in the 'network list'. To use the USB devices connected to the UTN server, you have to
add the UTN server to the 'selection list'. The devices shown in the selection list can be administrated and the con-
nected USB devices can be used. Working working with the SEH UTN Manager is described in detail in the chapter
’Working with the SEH UTN Manager’ 33.
Figure 2: SEH UTN Manager
WARNING
UTN (1) and the corresponding SEH UTN Manager only work in IPv4 networks.
In IPv6-only networks only the myUTN Control Center (6) can be accessed to
administrate the UTN server.

The following applies to the instructions:
• not case-sensitive
• one or more space characters are allowed
• max. length is 128 byte
• only the ASCII format can be read.
In addition, a TAN is needed to execute updates or parameter changes. To begin with, you have to get a status
page via email (Table 1 14) because it contains the TAN. You enter the received TAN into the email message
body. A space character must follow.
A DNS server is configured on the UTN server 21.
In order to receive emails, the UTN server must be set up as user with its own email address on a POP3 server.
POP3 and SMTP parameters have been configured on the UTN server 23.
1. Open an email program.
2. Write a new email:
- As recipient enter the UTN server address.
- Into the subject line enter an instruction. cmd: <command> [<comment>]
Commands and comment: Table 1 14.
- Into the email message body enter a TAN, if applicable.
3. Send the email.
The UTN server receives the email and carries out the instruction.
Commands Option Description
<Command> get status You get the UTN server status page.
get parameters You get the UTN server parameter list.
set parameters Sends one or more parameters to the UTN server which will then
be adopted by the UTN server.
