Purpose
UTN servers comprise USB Deviceservers and USB Dongleservers. As USB Deviceservers they make non-networkready 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 connected to the USB ports of the UTN server. Then the UTN (UTN = USB to Network) functionality and the corresponding 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.
Important:
The Dongleservers myUTN-80 and myUTN-800 are exclusively designed for the deployment of USB dongles.

3.1 How to Configure IPv4 Parameters
In the hardware installation ( ‘Hardware Installation Guide‘) the UTN server is connected to the network. The
UTN server then checks if it gets IP address dynamically via the boot protocols BOOTP (Bootstrap Protocol) or
DHCP (Dynamic Host Configuration Protocol). If this is not the case, the INU server assigns itself an IP address via
Zeroconf from the address range which is reserved for Zeroconf (169.254.0.0/16).
Important:
If the UTN server is connected to an IPv6 network, it will automatically receive an
additional IPv6 address 20.
The IPv4 address assigned to the UTN server can be found via the software tools 'SEH UTN Manager' and 'InterCon-NetTool'. This step usually is carried out during the initial set up (
To optimally embed the UTN server into a TCP/IP network, you can configure different IPv4 parameters and/or
manually assign a static IP address to the UTN server.

Table 3: IPv4 parameters
Parameters Description
DHCP
BOOTP
ARP/PING
IP address IP address of the UTN server.
Subnet mask Subnet mask of the UTN server.
Gateway IP address of the network's standard gateway which the UTN server uses.
Enables or disables the protocols DHCP, BOOTP, and ARP/PING.
The IP address assignment via DHCP and BOOTP is automatic if one of these
protocols is implemented in your network.
You can use the commands ARP and PING to change an IP address which was
assigned via Zeroconf. The implementation depends on your system; read the
documentation of your operating system.
We recommend disabling these options once an IP
address has been assigned to the UTN server.
Subnet masks are used to logically partition big networks into subnetworks. If
you are using the UTN server in a subnetwork, it requires the subnet mask of
the subnetwork.
With a gateway, you can address IP addresses from other networks.

3.2 How to Configure IPv6 Parameters
IPv6 (Internet Protocol Version 6) is the successor of the still predominantly used IPv4 (Internet Protocol Version
128
4). IPv6 offers the same basic functions but has many advantages such as the increased address space of 2
32
(IPv6) instead of 2
(IPv4) IP addresses and auto configuration.
Important:
IPv6 address notation differs from IPv4: An IPv6 address consists of 128 bits. The
normal format of an IPv6 address is eight fields. Each field contains four hexadecimal digits representing 16 bits.
Example:
2001:db8:4:0:2c0:ebff:fe0f:3b6b
As a URL in a Web browser, an IPv6 address must be enclosed in square brackets.
This prevents port numbers from being mistakenly regarded as part of an IPv6
address.
Example:
http://[2001:db8:4:0:2c0:ebff:fe0f:3b6b]:443
The URL will only be accepted by browsers that support IPv6.
You can embed the UTN server into an IPv6 network.
WARNING
UTN ( 1) and the corresponding SEH UTN Manager only work in IPv4 networks.
The InterCon-NetTool also only works in IPv4 networks.
In IPv6-only networks only the myUTN Control Center ( 6) can be accessed to
administrate the UTN server.
The UTN server will automatically receive one or more IPv6 addresses in addition to its IPv4 address. To optimally
embed the UTN into your network, you can configure IPv6 parameters.
1. Start the myUTN Control Center.
2. Select NETWORK – IPv6.
3. Configure the IPv6 parameters; Table 4 20.
4. Click Save & Restart to confirm.
The settings will be saved.
Table 4: IPv6 parameters
Parameters Description
IPv6 Enables/disables the IPv6 functionality of the UTN server.
Automatic configuration Enables/disables the automatic assignment of the IPv6 address to the UTN
server.
IPv6 address Defines an IPv6 unicast address in the format n:n:n:n:n:n:n:n which is manually
assigned to the UTN server.
• Every 'n' represents the hexadecimal value of one of the eight 16 bit elements of the address.
• Leading zeros can be omitted.
• An IPv6 address may be entered or displayed using a shortened version when
successive fields contain all zeros (0). In this case, two colons (::) are used.
Router Manually defines a static router to which the UTN server sends its requests.
20
myUTN User Manual Windows Network Settings
Parameters Description
Prefix length Defines the length of the subnet prefix for the IPv6 address. The value 64 is pre-
set.
Address ranges (e.g. your network) are specified with prefixes. To do this, the
prefix length (number of bits used) is added to the IPv6 address as a decimal
number and the decimal number is preceded by '/'.
3.3 How to Configure WLAN
The 'myUTN-55' is a WLAN device (Wireless Local Area Network) and supports the following standards:
• IEEE 802.11b
• IEEE 802.11g
• IEEE 802.11n
You can view the current WLAN settings in the myUTN Control Center under NETWORK – WLAN.
To optimally integrate the UTN server into your network, configure the WLAN parameters to match your WLAN
settings (network name, encryption, etc.). For this purpose, the UTN server must already be embedded into your
WLAN and be addressable. The initial setup is described in your product's
You know the settings of the WLAN.
The UTN server is within the WLAN range.
'Quick Installation Guide'.
Important:
If the UTN server changes the network, it may receive a new IP configuration. If this
is the case, the connection to the myUTN Control Center is interrupted.
1. Start the myUTN Control Center.
2. Select NETWORK – WLAN.
3. Configure the WLAN parameters; Table 5 21.
4. Click Save & Restart to confirm.
The settings will be saved.
Table 5: WLAN parameters
Parameters Description
Mode Defines the communication mode (network infrastructure):
• Ad hoc: Your WLAN is a decentralized ad-hoc-network in which devices
communicate directly with each other (peer-to-peer).
• Infrastructure: Your WLAN is an infrastructure network with an access point/
router as centrals communication hub. The access point is connected to the
fixed network with a cable.
Network name (SSID) Enter your WLAN’s network name, also known as SSID (Service Set Identifier).
21
myUTN User Manual Windows Network Settings
Parameters Description
Roaming Enables/disables roaming (switching from one access point/router to another):
If your WLAN covers a widespread area with several access points/routers (with
identical settings) and the UTN server changes position, the UTN server will
automatically switch to the better signal without loss of connection if roaming
is activated.
(Infrastructure mode only)
Channel Enter your WLAN's channel (frequency range).
(Ad hoc mode only)
WARNING
Only use WLAN channels authorized for your country!
The UTN is an international product which supports a number of
channels. Channels are statutorily regulated by national authorities. So the UTN server might support channels which are forbidden to use in your country.
Inform yourself about national regulations.
Encryption method Select the encryption method that protects your WLAN.
Important:
We recommend to use hexadecimal keys for WEP.
Some access points/routers convert WEP keys in ASCII format to
hexadecimal format. In this case, the ASCII key on the UTN server
and the hexadecimal key on the access point/router do not match.
Use WEP key Defines the WEP key to be used.
Key 1–4 Defines the WEP keys. Four WEP keys are available. The key type defines the
max. number of characters as well as the permitted character set for the WEP
keys.
Important:
If your access point supports multiple WEP keys, make sure that
the key numbers on access point and UTN server are identical.
Example: The ABCDE must have the number 2 on both devices
(and not 1 on the access point and 2 on the UTN server).
PSK Defines the Pre Shared Key (PSK) for Wi-Fi Protected Access (WPA).
Authentication method Choose the authentication mechanism which is used in your WLAN.
For further information see ’How to Configure Network Authentication (IEEE
802.1X)’ 60.

DNS Enables/disables the name resolution via a DNS server.
Primary DNS server Defines the IP address of the primary DNS server.
Secondary DNS server Defines the IP address of the secondary DNS server.
The secondary DNS server is used if the first one is not available.
Domain name (suffix) Defines the domain name of an existing DNS server.
3.5 How to Configure SNMP
SNMP (Simple Network Management Protocol) is protocol for configuring and monitoring network elements. The
protocol controls communication between the monitored devices and the monitoring station (SNMP management tool). Information can be read and changed.
SNMP exists in 3 versions, the UTN supports version 1 and 2.
SNMPv1
SNMPv1 is the first and most simple SNMP version. A disadvantage is the insecure access control which is the community: a community groups monitoring station and monitored devices. This makes their administration easier.
There are two types of communities, read-only and read/write. For both the community name is also the password used between the monitoring station and the monitored devices. As it is transmitted as clear text, it does
not offer sufficient protection.
SNMPv3
SNMPv3 is the newest SNMP version. It contains enhancements and a new security concept which includes,
amongst other thins, encryption and authentication. Therefore, a SNMP user with name and password must be
created in the monitoring station. This user must then be specified in the UTN server.
Important:
The user accounts are also used to access the myUTN Control Center and thus are
to be defined under SECURITY - Device access ’How to Protect Access to the
myUTN Control Center (User Accounts)’ 53.
23

3.7 How to Configure Email (POP3 and SMTP)
The UTN server can be administered via email ( 15) and offers a notification service ( 31) which sends you
status and error messages via email. To use these features, the email protocols 'POP3' and 'SMTP' must be set up
on the UTN server.
A client, e.g. the UTN server, uses POP3 (Post Office Protocol Version 3) to fetch emails from a mail server. POP3
must be set up on the UTN server so that it can be administered via email.
SMTP (Simple Mail Transfer Protocol) is used to send and forward emails. The UTN server needs SMTP for the administration via email and the notification service.
