The Power LED illuminates as soon as the UFX 314 is supplied with power. The status is indicated using the Error
LED and Event LED. The Event LED illuminates during the start phase and extinguishes as soon as the UFX 314
is ready. The Error LED and Event LED illuminate continuously during a software update. At the end of the update,
the Event LED extinguishes. When the device is then re-started, the Error LED also extinguishes, and the Event
LED illuminates at the start.
In normal operation, the Error LED and Event LED signal the presence of messages. An illuminated Event LED
signifies that information has been written to the log. If the Event LED is flashing, a warning has been generated,
it should still be possible to continue to operate the UFX 314. The flashing Error LED signifies that an error
has occurred and the correct operation of the UFX 314 is no longer assured. If the Error and Event LED flash
alternately, a serious error has occurred making normal operation more or less impossible.

3. Installation
3.1 Installation
The demultiplexer is installed in the 1 HU fan unit that is mounted above the base unit.
For this purpose the following steps are required:
Q
Fit the UFX 314 into the 19” front panel (1 HU) supplied
Q
Remove the pre-assembled blanking plate
Q
Connect straight connectors on connecting cables to the demultiplexer (mini-DIN sockets 1 ... 12)
The angled version is to be connected to the modules
If a modem is being used, an RS 232 adapter must be connected (special accessory, not included with the
Q
UFX 314). The modem operates independently of the demultiplexer to which it is connected
Q
Now push the demultiplexer into the 1-HU front unit from the front and screw into place
Q
Then connect the power supply unit power cable to the blue terminals (black = ground, brown = 12 V 5)
Q
The channel unit → UFX 314 connecting cables should always be laid to the right along the related channel
unit (exception: channel unit on the extreme right)
Where the following text refers to a switch, a hub can also be used as an alternative. It is also possible to connect
the control PC to the switch. If only two UFX 314 are to be connected together, a crossed Ethernet cable can be
used - however in this case a control PC can then only be connected using USB.

Connect the power cable for the UFX 314 to the
screw terminals in the power supply for the base
unit
3.2 UFO®compact controller
The UFO®compact controller can be connected to any of the demultiplexers. However, it is to be noted that the
controller only operates with the demultiplexers that belong to the same group to which it is connected. The usage
of an older UFO®compact controller prior to software version 9.20 is in principle possible, however there may be
connection problems with the channel units.
Only one control system can be active per group, this means that you can only access the group using one
UFO®compact controller or with one USW 30. As the groups are independent of each other, several groups in a
network can be controlled at the same time.
3.3 Network configuration
Connect several UFX 314 using a network. If you want to integrate the devices into an existing network, you should
consult the responsible network administrator to prevent problems from the start. Firewall and antivirus applications
may adversely affect the function.
The network configuration for the UFX 314 can only be undertaken using the controller software USW 30 and is
described in section 7 of the manual provided with the software.
In the delivery status, every demultiplexer is set to “Zeroconf”. Microsoft Windows also uses this method if a fixed
IP address has not been defined and a DHCP server is not available.
The related standard was published by the IETF under “RFC 3927” 1). The devices in the network select a spare
IP address from the range 169.254.1.0 to 169.254.255.0 and use the network mask 255.255.0.0.
The USW 30 connects with a demultiplexer in the group using TCP port 9312 and can then communicate with all
other multiplexers in this group over this connection. It does not matter to which device in a group the USW 30
connects. Between the UFX 314 a TCP connection on port 9313 is used.
To establish a connection via a router, the router must forward port 9312 to a UFX 314.
The UFX 314 does not have any access protection for Ethernet or USB access, for this reason instead of simple
port forwarding, the usage of a virtual private network (VPN) should be considered. You will find information on
VPN in the related specialist literature and on the Internet.
The “Multicast DNS” 2) and “DNS Service Discovery” 3) protocols used for the network search use Multicast packets
on UDP port 5353. The network is searched by each UFX 314 to find other devices in its group.

3.4 USB installation
3.4.1 Microsoft Windows
You will find the driver for the connection of a PC using USB on the USW 30 control software CD (not included).
To install the driver, you will need administrator permissions on the PC. The installation is described based on the
English version of Windows XP.
If the UFX 314 indicates an error after connecting/changing connections, or if it is not correctly detected by Windows,
disconnect it from the PC and restart it using the Reset button. Before reconnecting to the PC, wait until the
demultiplexer has started completely (see 2.3 Status LEDs).
After the UFX 314 is connected, a wizard for installing
new hardware appears.
Choose “No, not this time” and click “Next” to open the
next page in the wizard.
Select “Install from a list or specific location”.
Select “Search for the best driver in these locations”
and “Include this location in the search:”.
By clicking “Browse” you can open a dialog box where
you can open the folder "UFX314\drivers" on the
USW 30 CD.
In the event of an update to the USW 30, the drivers
can be found in the software installation folder.

Ignore this message by clicking “Continue Anyway”.
The driver is now installed.
Note:
After driver installation has been completed, a new network
connection will be available (name “USB Ethernet/RNDIS”)
which can be configured and used as a standard (Ethernet)
network connection.
The driver installation is now complete.
Windows confirms again that the driver has been
installed.
If this message does not appear or if you have selected
“Zeroconf” (factory setting) as the address for UFX 314
network configuration, you do not have to take any
further steps.
Otherwise, double-click the network symbol in the task
bar or select the respective network connection
(name “USB Ethernet/RNDIS”) in the Control Panel
under “Network connections”.
Important note:
The warning message (network symbol with an exclamation point on the task bar) can be ignored in this case.
This warning only means that Windows has assigned an automatically determined configuration (“Zeroconf”) to the network
connection, and therefore may be the reason why there is no connection to the Internet or to other network resources. It is,
however, possible to activate the UFX 314 via USB without any restrictions, as long as the the mode “Zeroconf” was selected
for address allocation (factory setting).

Click “Properties”.
Select “Internet Protocol (TCP/IP)” and then click
“Properties”.
10
Download from Www.Somanuals.com. All Manuals Search And Download.
Select “Use the following IP address”.
You must complete “IP address” and “Subnet mask” to
suit the address of your demultiplexer.
If the UFX 314 is operated with DHCP, ask the person
responsible for the DHCP server for the correct settings
- in most cases “Obtain an IP address automatically”
works.
If “Zeroconf” (factory setting) is used on the UFX 314,
select “Obtain an IP address automatically”. If the
UFX 314 is set to “Manual”, you must set an IP and
subnet mask suitable for the device.
Alternatively, you can also assign an address from the
range 169.254.0.1 to 169.254.0.254, the related subnet
mask is 255.255.0.0.
Leave both dialog boxes using “OK”.
The connection has now been setup.
If there are still problems, contact your network administrator.
3.4.2 Linux
The driver is included in Linux from version 2.6, you may need to re-compile the kernel to activate the support.
On the USB the UFX 314 is identified by Linux as “USB Communication Class Ethernet device”.
4. Software update
You will find software updates for your UFO®compact software at “http://www.kathrein.de/esc-kathrein/download/
ufo/ufo_compact_select.cfm”. The updates for the UFX 314 are loaded using the Kathrein service tool (KUBdate)
from version 1.1.2. All demultiplexers in a group must be updated.
In KUBdate, first select in “Supported devices” UFO Compact → Demultiplexer → UFX 314.
In “Selected device”, you can open the connection settings using “Device settings”, here you can select the group
to be updated using “Search in the network”. Using “Software update” you can select an update bundle and start
the update. For further information, please refer to the KUBdate manual.
If the update fails, e. g. due to a power failure, the software can be repaired using a web browser or a USB stick.
Updating using a web browser is described in section 5.4.
For an update using a USB stick, you will need the actual update archive.
You can extract the update archive from the Kathrein update bundle using a ZIP application; then save the update
archive on a USB stick. The name of the file on the stick must start with “UFX314_” and have the same ending as
the file in the bundle, e. g. “.tar.gz”.
Should the bundle contain several archives, the file “bundle_info.xml” will provide information on which archive is
for which hardware. Insert the stick in the demultiplexer to be repaired and then press the Reset button. The port
LEDs may flash while the USB stick is searched. The demultiplexer copies the archive before it starts the update.
As soon as the actual update starts, indicated by the illumination of Error LED and Event LED, the USB stick can
be removed. After the update, the demultiplexer will re-start. If the stick is still inserted at this time, the process
will start again from the beginning. Updating using a USB stick is only for problem cases and only the one
demultiplexer is updated.

5. Web interface
Every UFX 314 has a web interface that can be reached by entering the IP address for the demultiplexer in a web
browser. You can determine the address using USW 30 or KUBdate.
5.1 The main page
The main page is divided into two areas, at the top the serial number, IP address and other links for the
demultiplexer and below a list of all demultiplexers found, sorted by groups. All the links for a demultiplexer can be
password-protected. The password is the same as for the PPP access and can be set using USW 30. As supplied,
no password is set and access is therefore open.
5.1.1 The device group box
You can open the log using “View Log”. Using the “Switch Debuglog” command you can enable and disable the
storage of debug messages in the log. However, only new messages will be affected. You can clear the log using
“Clear Log” and reset the status LEDs on the device. The “View Unit Status” link opens a page with more detailed
information. You can re-start the UFX 314 using “Restart Unit”. Using “Tagging on” you can make the 12 port LEDs
flash for around one minute so that the unit can be identified.
You can open the web update using “Update Unit”. With “Informations about used Opensource Licences” you can
open an overview of the open source used in the device and the text for the related licences.
You will also find both these items here in the manual in section 7.1 or in the appendix.
5.1.2 The system group box
The devices are sorted by groups. For each group the number in hexadecimal notation and the comment defined
by the user are displayed. The group number is a link to the base unit in each system. Each demultiplexer is
displayed in a dedicated line. The serial number is also a link to the main page for the related unit. If you are
already on the main page for a unit, the related links are not available. After the serial number there is a schematic
diagram of the demultiplexer.
The diagram is divided into three parts. The three status LEDs can be seen on the right. The port LEDs are at
the bottom left. The channel units connected are shown at the top left using blue squares. The information on the
diagram refreshes automatically if JavaScript is enabled, or when the page is reloaded. Beside the diagram there is
a link to the log, a link for re-starting the unit and links to enable and disable the flashing of all 12 port LEDs.
5.2 Log page
At the top the Log window contains a list of all error messages that have occurred. These error messages are
stored in non-volatile memory by the UFX 314 and can also still be read after a reset. The time information in the
error message is also a link to the related message in the bottom part of the window. The UFX 314 does not have a
dedicated clock, the time is therefore calculated from each start starting from 1.1.1970 at 0:00 hours.
Old error messages are not deleted automatically. For this reason the user should delete the messages using
the link on the main page, once they are no longer required. The bottom part of the window contains the
current messages. The current messages are deleted each time the device is started. Older messages are also
automatically deleted if there is not enough space. Error messages are listed here again so that they can be
analysed in context. All messages are colour-coded:
Grey font on white background
Black font on white background
White font on green background
Debug messages
Normal information
Message that the device is ready for operation after a
restart.
Message that the device is shutting down for a restart
or an update
White font on blue background
Black font on yellow background
Red font on yellow background
Yellow font on red background
Warnings
Error messages
Fatal error

5.3 Status page
The Status page contains information on network addresses, software and hardware versions as well as the time
and capacity utilisation.
5.4 Update page
On this page you can update the device's software. Normally the software is updated using the application
KUBdate. You can extract the update archive from the Kathrein update bundle using a ZIP application; then upload
it using this page. Should the bundle contain several archives, the file "bundle_info.xml" will provide information on
which archive is for which hardware.
Updating using this web page is only for problem cases and only this one demultiplexer is updated.
6. Modem access
Any modem supported by the operating system can be used in the PC.
To connect the modem to the demultiplexer, a USB-RS232 adapter is necessary.
Currently the following modems are supported by the UFX 314:
Manufacturer
Develo (formerly Elsa) Microlink 56k Fun II
MicroLink ISDN i
Model
Type
Analogue
ISDN
3Com US Robotics
Siemens
Sporster Flash
MC 35
Analogue
GSM
The modem installed must be set to a speed of 115200 Baud or to automatic baud rate detection. You will find the
instructions for making this setting in the manual for your modem. To ensure correct initialisation of the modem, the
modem should be switched on and connected to the adapter before the adapter is connected to the UFX 314.
Initialisation is automatic after connection, or, if an adapter is connected when the demultiplexer is started.
6.1 Setting up in Microsoft Windows
Setting up the connection is described based on the English version of Windows XP. In the following it is assumed
that the modem is already installed in the PC. If this is not the case, consult the manual for your modem or your
system administrator. To setup a new connection, on the Start menu select the “Control Panel” command and
double-click “Network connections” in the window that appears. Now select "New Connection Wizard".
Open the next page in the wizard by clicking “Next”.

Enter a meaningful name for the connection to this
demultiplexer as the name for the Internet service
provider.
Enter here the telephone number to which the
demultiplexer is connected.
Enter here the same user name and password as you
have set using USW 30.
A check mark must also be set at “Make this the default
Internet connection”.
If you have not entered a password using USW 30,
or have entered a blank password, the UFX 314
will accept any login, irrespective of user name and
password. So anybody who knows the telephone
number can dial into the system.
For this reason, it is strongly recommended to assign a
user name and password.

The “New Connection Wizard” is completed with this
dialog box.
If you want, you can select “Add a shortcut to this
connection to my desktop” to be able to make the
connection in future directly from the desktop.
Otherwise, you will find the connection in the network
connections where you have just opened the wizard.

Now click “Dial” to establish the connection. The
settings made are saved and do not need to be made
again next time.
6.2 Setting up in Linux
It is recommended to use a terminal program with a graphic interface such as KPPP. It should be noted that all
modems currently available with a USB interface have been primarily developed for Windows and they may
therefore be difficult or impossible to use with Linux.
It is significantly easier to use serial modems, if necessary also with USB-RS 232 adapter.
Start KPPP. Normally this is in “KDE-Menu” → Internet → Dial in.
Click “Configure ...” to open the Configuration
dialog box.

Choose the connection you have just setup and, if you
are using several modems, the correct modem. Then
enter the same user name and password as you have
set using USW 30.
The connection is established using “Connect”.
If you have not entered a password using USW 30
or have entered a blank password, the UFX 314 will
accept every login, independent of user name and
password. So anybody who knows the telephone
number can dial into the system.
For this reason, it is strongly recommended to assign a
user name and password.
