2 Introduction
2.1 Safety instructions
Remove both mains plugs before opening the device!
Exercise caution when servicing the power supply unit. There is the risk of making contact with
parts which are live even when disconnected from the mains!
Operating indicators - where present - merely indicate the presence of DC voltages isolated from
the mains which supply power to the components of the device. However, operating indicators
which are not lit do not under any circumstances mean that the device is completely disconnected
from the mains or non-live.
Both mains switches or mains plugs are used as a mains isolator and must therefore be accessible and able to be used at any time. When just one power supply unit is connected to the operating voltage and the mains switch is set to „on“, the device is in operation. If the second power
supply unit is also put into operation, one operates in idle mode for as long as the other power
supply unit is supplying power to the device.
The device must be opened only by authorized specialist personnel inspected by the Chamber
of Industry and Commerce. The device must be repaired only by authorized specialist personnel
inspected by the Chamber of Industry and Commerce, or by sending it to ASTRO with the precise
description of the fault.
The mains cable(s) must be replaced only with original mains cables. Fuses must be replaced
only with fuses of the same type, value and melting characteristic.
Always observe:
DIN VDE 0701 - Parts 1 and 200, maintenance
EN 50 083 - Part 1, safety requirements
Do not carry out servicing work during thunderstorms
2.2 Assembly instructions
Protection from environmental inuences:
The device must be connected and operated in dry rooms only. It must not be exposed to spray,
water droplets or similar inuences. If condensation has formed, wait until the device has completely dried out. Objects lled with liquid must not be put down on the device.
The permitted ambient temperature is 0 ... 45°C.
Assembly environment:
The device is intended for operation in 19“ racks, which are preferably metallically conductive
and which have sufficient air convection. It should be operated away from radiant heat and other
heat sources. The device must be installed only in rooms in which the permitted ambient temperature can be maintained even if the climatic conditions change. To avoid trapped heat, it must be
ensured that air can circulate freely on all sides. Assembly in niches and unintentional covering of
the ventilation holes must be avoided at all times.
2.3 Equipotential bonding / grounding

U 262
The subscriber network must be and remain grounded as per the regulations in EN 60728 Part
11, even if the device is removed.
The equipotential bonding on the U 262 is provided by means of the xing straps on the device
or by means of the grounding clamp on its back. Appliances within arm‘s reach must be mutually
integrated into the equipotential bonding.
Operation without connection to a protective conductor, device grounding or device equipotential
bonding is not permitted!
2.4 Servicing and repair
Caution:
The device must not be opened by the user, since the device does not contain any user-serviceable parts!
If all instructions are observed and the device is used as stipulated, no servicing is required.
Repairs must be carried out exclusively in the factory.

3 General introduction
3.1 Connecting the U 262 to a PC / Laptop
Applying the operating voltage turns on the U 262 automatically. Following the boot phase
(approx. 30 seconds), the display shows the two Management IP addresses (lines 2 & 3), and
any error messages (line 4).
If the device is connected to a PC / laptop by means of one of the network ports and once the PC/
laptop has been appropriately congured by means of the network settings, conguration of the U
262 can be started following input of the IP address in the address line of the Web browser.
3.2 The web browser user interface
The web browser user interface is split into a topframe, leftframe and mainframe.
The topframe
contains general information about the gateway.
Figure 1: General information in the topframe of the Web browser user interface
This information can be read as follows:
„SW: Jul 8 2008“ is the description of the software level on the U 262 Gateway,
„FW 1.4“ is the level of the rmware in the U 262 Gateway,
„HW: 2“ is the Gateway‘s hardware version,
„Up: 0d 00:03‘25““ is the connection time measured from the instant of logging in,
„Time (UTC):“ indicates the time on the U 262.
In the above gure, alignment with the SNTP server has not yet taken place, and the U 262
therefore indicates the year 1970. The bold line for „Location“ and „Contact“ is obtained from the
settings in the chapter „User Administration“.
The right-hand part of the topframe reects the display and the status LEDs of the U 262, i.e. the
Web browser user interface reproduces the exact view of the U 262.

User Guide
U 262
Page 8
Figure 2: View of U 262 display and LEDs in the Web browser user interface
In the example for gure 2, the device is reporting the error „IP RX4A Data Loss“, and precisely
this error message can also be seen in the display of the U 262.
The leftframe
contains the navigation bar through the various submenus, which are described in detail in the
chapters which follow.
The mainframe
displays - in line with the selection in the navigation bar in the leftframe - the submenu.
4 Login
Before the Gateway can be congured, it is necessary to log in. This is done using the „Login“
submenu.
Figure 3: Input mask for login
Clicking on the „Login“ submenu opens the input mask for login (see gure 3). The standard
factory setting is:
„Username: admin and password: astro“
8
User Guide
U 262
Page 9
When the access data have been input correctly, it is possible to continue conguration. For
security reasons, the usernames and passwords as set by the factory should be changed. This
allows unauthorized access to be prevented. Only one user/BC 4 can ever be logged in on the U
262 Gateway. The very bottom of the leftframe of the Web browser user interface shows which
user is currently logged in.
5 Settings
Clicking on the „Main“ submenu takes you to the basic settings of the U 262.
NOTE:
All settings made must be transferred to the Gateway, and therefore activated, using the „Submit“ button. To save the data, make sure that you click on the „Save“ button after all parameters
have been congured, otherwise the settings which have been changed will be lost following a
reboot.
5.1 Setting the IP interfaces
The „IP Interface Settings“ area is used to make the settings for the four IP interfaces (Management A & B, and Data A & B).
The „MAC“ line displays the Mac address of the respective IP interface. The lowest Mac address
is required for licensing further features of the U 262 (see the chapter „Licensing“).
The „Active“ line can be used to activate and deactivate the individual IP interfaces, and the
„Mode“ line displays the bandwidth of the IP interface connected to the U 262. This bandwidth is
recognized by the U 262 automatically.
Figure 4: Detail from basic settings of the U 262: IP Interface Settings
The IP addresses („Address“ line), subnetwork masks („Subnet“ line) and standard Gateways
„Gateway“ line) are input using the keypad. Normally, it is only necessary to input a Gateway
under Management A.
NOTE:
Please use different IP addresses for every interface and different address ranges if the interfaces
are connected to different network segments. Input 0.0.0.0 for unused or unknown Gateways.
9
User Guide
U 262
Page 10
5.2 Setting the IP Management interfaces
The „IP Management Settings“ area is used to stipulate the DNS server, to congure up to four
SNMP Trap recipients and to input two SNTP servers for obtaining the time reference. The time
source used may then be „SNTP Server“ or „IP Rx 1“ to „IP Rx 16“ or „ASI TP“. Only the licensed
„IP Rx“ can be used.
Figure 5: Detail from the basic settings of the U 262 „IP Management Settings“
NOTE:
Please use different IP addresses. Input 0.0.0.0 for unused or unknown DNS, SNMP or SNTP
addresses.
5.3 Storing and loading settings / reboot
The „Save“ button is used to save all settings made in the ash memory and to restore them even
after mains failure or a reboot. The „Load“ button is used to restore the last operating parameters saved in the ash memory and to reject changes which were made previously and were not
stored.
Figure 6: Detail from the basic settings of the U 262 „Save, Load, Default & Reboot“
„Default“ is used to restore the factory settings, and „Reboot“ prompts the advice to restart with
the operating parameters saved in the ash memory.

6 Test generator
Clicking on the „Test Gen“ submenu takes you to the test generator settings. This internal test
generator is able to produce a test signal in order to perform a connection test, for example, and
to test this connection using a data stream.
Figure 7: Conguring the test generator
The generated data stream comprises zero packets with a length of 188 and can be congured
in a range from 1 - 197 Mbps. If the system contains several U 262 Gateways, a packet ID can
be allocated to distinguish the test signals.
7 Configuring the input multiplexer
Clicking on the „Input Mux“ submenu takes you to the input multiplexer settings. It is possible to
assign one ASI input stream to different IP TX. It is not possible to assign several ASI streams
to one IP TX (no multiplexing of IP multicast groups out of several ASI streams). The U 262 has
16 ASI inputs which can be used - depending on licensing - to convert a maximum of 16 IP data
streams.
Figure 8: Conguring the input multiplexer
11
User Guide
U 262
Page 12
The „Input Mux Settings“ are used to assign an IP TX port to each ASI input of the U 262 Gateway.
An ASI stream can also be routed to several IP TX, so that the U 262 can also be used as an IP
splitter. To provide a better overview, the respective row and column of the output matrix will get
a red background if the mouse pointer will be shifted over it. The ASI signal can also be inverted.
Please consider that the ASI signal has to be available in packet (burst) mode.
8 IP setting for transmission and reception mode
Clicking on the „IP TX & IP RX“ submenu takes you to the settings for the transmission and
reception modes of the U 262. This page provides an overview of the transmission port (IP TX) of
the U 262, the general settings of the reception ports (IP RX Common Settings) and the detailed
settings of the reception ports (IP RX Channel Settings).
Figure 9: Overview of the configured transmission ports
The overview shows the configuration of the individual transmission ports. The U 262 Gateway
in the above example is equipped with 16 reception licenses, i.e. 16 ASI input streams can be
converted to 16 IP multicast groups and be distributed over the network interface. The links “TX1”
to “TX16” take you to the detailed configuration of the respective port.
The transmission ports can be activated and deactivated in this mask, specifically differentiated
according to Data A and Data B interface. If the user has a redundant network infrastructure (e.g.
bidirectional backbone), it may make sense for the data to be transmitted via both data interfaces.
For the general settings of the reception port, it is possible to choose between “Data A” and “Data
B” as the active reception interface.
12
User Guide
U 262
Page 13
Figure 10: General settings for the reception ports (IP RX Common Settings)
If the network infrastructure is of redundant design and if “Data A” and “Data B” have the same
signal applied to them via a different supply line, the U 262 Gateway can be configured such that
in the event of a signal loss the active data port is automatically switched over (“Automatic” selection). If this redundant supply line does not exist, the “Static” option should be selected.
9 IP setting for transmission ports
NOTE:
The transmission ports should be configured in agreement with the network administrator in order
to ensure that no problems in the network occur!
Clicking on the “IP TX 1” to “IP TX 16” submenu takes you to the IP settings for the transmission
port.
9.1 Transmit port
The “Transmit Port” line can be used to select the port which is used to send the multicast
group.
A value ≥ 1024 should be set for this in order to avoid conflict with services (Port 21: FTP, Port
80:
http, Port 110: POP3 etc.).
9.2 Destination IP
The “Destination IP:Port” line is used to assign an IP address and a UDP port to the ASI transport
stream converted according to IP. Usually, a multicast address is input here, since this allows
the data stream to be received by several IP receivers. By contrast, a unicast address can be
received only by one IP receiver.
Multicast addresses are in the IP address space 224.0.0.0 to 239.255.255.255, the range
224.0.0.0 to 224.0.0.255 being reserved for administrative purposes.

Figure 11: Conguring the transmission port (IP TX1 to IP TX16 Channel Settings)
9.3 Destination MAC
The “Destination MAC” is obtained automatically from the input “Destination IP:Port” and is
displayed here as additional information.
9.4 Type of Service / Time to live
The “TOS/TTL” line provides the option of inputting the “Type Of Service” and the “Time To Live”.
Should the various services not be distinguished in the given network, it is not necessary to alter
the settings ex factory. The TTL indicates the permitted number of hops via a router and should
be defined such that the data packets cannot leave the network.
9.5 VLAN Tags
If the U 262 Gateway is intended to cover various VLANs, it is possible for the data packets to be
assigned different VLAN tags. This ensures that data packets are routed only to the desired
VLANs, or each VLAN receives only the data packets which are intended for it.
9.6 TS packets per frame / RTP / FEC
The format of the IP data stream can be determined in the bottom part of the table shown in figure
12. The number of transport stream packets per Ethernet frame can be stipulated between 1
and 7. In networks in which secure data transmission is ensured (e.g. proprietary backbone), the
number of packets can be set to 7, since the loss of an Ethernet frame is improbable. In networks
with nonsecure data transmission, a small value needs to be chosen in order to minimize the loss
of useful data in the event of an Ethernet frame being lost.
The “Protocol Encapsulation” line can be used to append an additional RTP header (Real Time
Transport Protocol) to the connectionless UDP/IP Ethernet frame. This header allows the individual transmitted Ethernet frames to be numbered in order to detect Ethernet frames which have
been lost or have arrived in the wrong order on a receiver. Error correction is not included by the
RTP header.
The U 262 Gateway is equipped with an optionally engageable FEC. This FEC forms checksums
from a matrix and transmits these checksums to the UDP ports + 2 and + 4 in the same multicast
group. When the data are recovered, these checksums are aligned and errors can be corrected.
Two different modes of FEC are possible: one-dimensional FEC, in which sums are formed only
over the columns, and two-dimensional FEC, in which the sums are formed over columns and
rows.
Figure 12: Conguring the FEC
14
User Guide
U 262
Page 15
The first drop-down selection field is used to stipulate the number of columns in the checking
matrix. There are 1 to 20 columns or the selection “Off” available here. The second drop-down
selection field is used to stipulate the number of rows in the checking matrix. There are 4 to 20
rows or the selection “Off” available here. The third selection field is used to select one-dimensional or two-dimensional FEC (Col+Row = two-dimensional/Col only = one-dimensional over
columns).
The mode of the FEC can be selected to be “Plain”, “Annex A” or “Annex B” in line with ProMpeg
COP3 (SMPTE 2022-1). Please note that plain FEC results in a burst behavior for the data rate,
and hence Annex A and Annex B are preferable. It should be noted that the product of the number
of columns (L) and the number of rows (D) is ≤ 100 (L x D ≤ 100).
10 IP setting for reception ports
Clicking on the „IP RX1-1 - IP RX16“ submenu takes you to the IP settings for the desired reception port.
Figure 13: Setting details for the reception port
The “Receive IP:Port” line is used to input the IP address and the UDP port at which the U 262
Gateway needs to receive the data stream.
15
User Guide
U 262
Page 16
The “Encapsulation” is selected according to the stipulation of how the input data stream has
been encapsulated by the transmission equipment. In RTP mode, every data packet must be
provided with an RTP header. This header contains numbering for the individual transmitted Ethernet frames in order to detect and possibly re-sought Ethernet frames which have been lost or
have arrived in the wrong order on the receiver. Error correction is not included in the RTP header
(RTP: can only receive RTP frames / UDP can receive both but cannot use the RTP header).
A data stream can arrive with a CBR (Constant Bit Ratio) in the U 262 Gateway, or with a VBR
(Variable Bit Ratio). In any case, CBR is used for MPTSs (Multiple Program Transport Stream)
but also for SPTSs (Single Program Transport Stream). However, SPTSs can also be sent with
a VBR.
Under “Packet Mode”, it is possible to select between “continuous” or “burst” for configuring the
respective ASI output connected downstream of the IP RX.
The TSIDs and ONIDs are displayed for information purposes in line with the selected transport
stream and, to provide a better overview of the transport streams, it is possible for an alias to be
input. If no alias is input, the name of the first service of the transport stream is entered automatically.

Clicking on the “Output Mux” submenu takes you to the output multiplexer settings
Figure 14: Example view of the output multiplexer
The received IP RX is supplied via the BNC socket on the front and can be inverted prior to conversion to ASI (inversion on / off). In addition the packet length can be determined to 188 or 204.
There is also the possibility to bypass one of the 16 ASI streams from the backplane to the BNC
socket on the front panel as well as the internal test generator signal (see chapter 6)

14 Licensing
Clicking on the „License“ submenu takes you to licensing. The features of the U 262 can be
upgraded from the factory-delivered state (1 IP TX & 1 IP RX) through to the full complement of
equipment (16 IP TX, 1 IP RX and TS analyzer) by purchasing software licenses.
Figure 17: Input mask for software licenses
A prerequisite for ordering further licenses is provision of the Mac address of the device. The Mac
address can be found either on the sticker on the back of the device (see illustrations on page
3) or in the Web browser interface. In this respect, the lowest Mac address is the important one.
When the Mac address has been provided, ASTRO will generate the license keys and supply
them by E-mail or on CD.
The format of the license keys is a text document (e.g. Lic001772000222.txt). The key or keys can
be inserted into the input mask using „Copy/Paste“, and clicking on the „Submit“ button transfers
the license to the U 262 Gateway. If the license is valid, this is conrmed by a message. An invalid
license is indicated by an error message.
15 Update
15.1 Update using (T)FTP Server
Clicking on the „Update“ submenu takes you to the settings for the U 262 software update. The
„(T)FTP Server address“ line is used to input the (T)FTP server address at which the current
software for the U 262 Gateway is stored.
The „Protocol“ line provides the option of selecting „FTP“ (File Transfer Protocol) or „TFTP“ (Trivial File Transfer Protocol). If the „TFTP“ option is chosen, it is not necessary to input the username
and the password.
„Path“ is used to input the path on which the U 262 software update was stored. It is necessary to
ensure that the software is stored in the indicated path (preceded and followed by „/“), otherwise
the update will not take place. Furthermore, it must be ensured that any rewall installed permits
the (T)FTP communication. In the „Update“ submenu, it is also possible to store the conguration
of the U 262 Gateway on an FTP server, or else to load a conguration into the U 262 Gateway.
Loading a conguration into the U 262 Gateway does not affect the settings of the IP interfaces.

15.2 Update using the example of a TFTP Server for Windows
Should there be no rm (T)FTP server set up for updating the U 262 Gateway, it is also possible
to transfer locally stored update les to the Gateway. For this, it is recommended that a TFTP
program be used. The procedure is explained below using the program „Tftpd32“.

The „tftpd32“ program is started directly from the folder with the U 262 update les. In the window
that opens, click on the „Settings“ button rst and make the settings as shown in Figure 21:
Figure 20: Settings for the tftpd32 TFTP program
To start the update, the server address which is input into the „(T)FTP Server address“ line now
needs to be the IP address of the local computer (Figure 19), and the protocol needs to be set to
TFTP. It is therefore also no longer necessary to input a username and a password. In the „File“
line, select the „Update“ option, and start the update by clicking on the „Submit“ button.
NOTE:
A reboot or network failure during an update procedure can result in the U 262 Gateway software
crashing fatally. The device would then need to be sent to the ASTRO factory for repair.
