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.
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 fixing 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.
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).
Figure 2: View of U 262 display and LEDs in the Web browser user interface In the example for figure 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.
When the access data have been input correctly, it is possible to continue configuration. 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.
5.2 Setting the IP Management interfaces The „IP Management Settings“ area is used to stipulate the DNS server, to configure 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.
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: Configuring the test generator The generated data stream comprises zero packets with a length of 188 and can be configured in a range from 1 - 197 Mbps.
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.
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.
Figure 11: Configuring 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 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 “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.
11 Configuring the output multiplexer 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.
12 User Administration Clicking on the „User“ submenu takes you to User administration. When delivered, the U 262 Gateway can be configured using three different items of access data. Username: admin, password: astro Username: user, password: astro Username: bc4, password: astro Figure 15: View of User Administration upon delivery NOTE: ASTRO does not have a master password! Should you forget your password, you will no longer be able to log in and the device will need to be sent in.
Figure 16: Analyzing the selected transport stream Wait until the „...done!“ message appears. Clicking on the „+“ or „-“ symbols displays or hides the details. Through selection of the „ASI TP“ as the TS to be analyzed, the TS analyzer also provides the option of analyzing externally applied ASI signals.
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.
Figure 18: Input mask for the U 262 software update 15.2 Update using the example of a TFTP Server for Windows Should there be no firm (T)FTP server set up for updating the U 262 Gateway, it is also possible to transfer locally stored update files 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 files. In the window that opens, click on the „Settings“ button first 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.
16 Log Book Clicking on the „System Log“ submenu takes you to the U 262 Gateway‘s log book. This documents all processes which are relevant to operation. Figure 21: Example view of the U 262 log book The processes are sorted according to the time of occurrence. The logfile is erased by checking „Check box to clear log on refresh“ and then clicking on the „Refresh“ button.
17 Statistics Clicking on the „Statistics“ submenu takes you to the statistics relating to the data transfer of the U 262 Gateway. This displays all statistics which are relevant to operation and which can be used for analysis.
18 Network properties The network properties can be displayed by clicking on the „Network“ submenu. The displayed characteristics are purely informative and serve to describe the network.
19 Logout Clicking on the „Logout“ submenu (only available when you are logged in) allows you to log out from the U 262 Gateway. Figure 25: Logging out from the U 262 Gateway If you confirm the question using the „Yes“ button, you are logged out. It is not possible to make any further settings without logging in again, but it is possible to view the U 262 Gateway‘s settings. The setting items are inactive, however.
