Introduction
Reuters World News Express (WNE) is a file based television delivery system that transmits Reuters Video News
(RVN) material, principally over satellite, as MPEG 2 video and XML scripts. The SkyStream Edge Media Receiver
(EMR) is a DVB receiver that extracts IP content from the WNE satellite feed. This IP content is then reassembled
into video and script files by the zBand software and stored on your WNE PC.
The EMR that you will have received from Reuters with your WNE installation is shown below:
The Web-based interface for the EMR is shown below:
Although, your EMR comes preconfigured for use, there are several procedures that you must complete yourself in
order to begin receiving data from Reuters WNE satellite. Each of these procedures are described within this
document:
•
•
Connect the EMR to the WNE PC (described in the Physical Equipment Installation and Connections section of
this document)
Tune the receiver to the Reuters Satellite signal and verify that IP data is being received and stored locally on
your WNE PC (the process by which this is accomplished is described within several sections of this document).

Accessing the EMR via the web interface
The most efficient method by which to configure your EMR is via the web-based interface.
1.
Turn on your EMR and the WNE PC. Accessing the EMR through the WEB GUI requires that both devices
share the same subnet address. All EMR LAN 2 ports default to an IP address of 172.16.2.2. (LAN 1 is supplied
with a default of 172.16.1.2).
2.
Change the IP address of the onboard NIC to match the subnet address on the EMRs LAN2 port (e.g.
172.16.2.100), with a Subnet Mask of 255.255.255.0.
3.
Enter the LAN 2 EMR IP address into an internet browser window.
EMR Configuration Guide Issue 10
WNE v.5.0

Note: A shortcut link may already exist in your browser’s Links section called Skystream Networks Edge Media
Router (also accessible via 172.16.2.2).
4.
The following EMR page will then be displayed. If you select one of the menu options in the left hand navigation
bar, you will be prompted to login (as shown below).
Figure 3 EMR web interface with login page
5.
To login, enter the default user emradmin. No password is required.
Note: If you are accessing the site for the first time or have just rebooted the EMR, you must supply the default user
name. Otherwise, you will generally not be prompted for a login.
The initial connectivity between your WNE PC and EMR has now been established. Next, you will need to
ensure that you have signal lock to the satellite.
Locking to the WNE signal
1.
Select Satellite Receiver from beneath the Statistics menu in the left hand navigation bar. The StatisticsSatellite Receiver page will display the NO LOCK status for the key values shown below. This indicates that
satellite parameters have not yet been entered into the EMR.

Figure 4 Statistics page with no signal lock
2.
Select Satellite Receiver from the Configuration menu in the left hand navigation bar. The Configuration –
Tuner 1 page will be displayed.
Figure 5 Configuration of EMR tuner settings
3.
Click Change Tuner Settings. The Configuration-Satellite Receiver 1 page will be displayed.
EMR Configuration Guide Issue 10
WNE v.5.0

Figure 6 Tuner configuration page
4.
Enter the parameters for the satellite that is applicable to your location. Refer to the tables in Figures 1 and 2 of
the Global Satellite Coverage section of this document for the relevant regional downlink parameters. The
settings you must reference are the D/L Frequency (L-Band Frequency), Symbol Rate and Polarization.
L-Band Frequency is often noted as:
•
KU Band Downlink Frequency – LNB LO Frequency.
•
C Band LNB LO Frequency – Downlink Frequency
A high proportion of LNBs used by subscribing Reuters Live clients tend to have a LO (Local Oscillator)
frequency of 10GHz. In the example in Figure 6 above, the L-Band Frequency value is 1200MHz.
In the example below, for an EMR unit in Europe, the frequency value is obtained by subtracting the D/L Satellite
Frequency value from SES-4 for the Europe region (see Figure 1) from a local oscillator (LO) frequency of
10GHz or 9.75GHz.
A few sample calculations are show below:
5.
•
10GHz LO i.e. 109857 MHz – 10000MHz = 985.7MHz.
•
9.75GHz LO i.e. 109857 MHz - 9750MHz = 1235.7MHz.
Once the correct parameters have been entered, click Apply to accept the changes. If the entered parameters
are correct, the Configuration - Tuner 1 page will be displayed. The Data Lock (FEC lock) field should now
display a green lock (as shown in Figure 9). This indicates that the EMR has locked to the WNE satellite signal.
Note: If a red light initially appears in the Data Lock (FEC lock) field, press F5 to refresh. The green lock light
should then appear in that field.

Figure 7 Successful data lock
Note: Refer to the Troubleshooting section at the end of this document if the signal has not locked.
6.
Once you have successfully locked onto the Reuters signal, you must configure the EMR to extract the IP data
from the satellite signal. This will include setting the relevant PID for the signal. Packet IDs (PIDs) are identifiers
used to tag different MPEG component packets within a satellite signal (e.g. video, audio or in the case of WNE,
IP data). WNE IP data is carried within the satellite signal on PID 3550.
Select PID Selection from the Configuration menu in the left hand navigation bar. The Configuration – PID
Selection page will be displayed.
7.
Click PID Selection. The PID Selection – Receiver 1 page will then be displayed.

8.
Enter the PID value of 3550 in the New PID field and select the decimal option. Click Add to add this PID to the
Active PIDs list for the EMR.
9.
The EMR is now successfully locked to the WNE signal and is extracting IP data from the appropriate PID value.
All IP data is carried on a multicast IP address and must be routed to the relevant EMR Ethernet port (e.g.,
Ethernet 2/LAN2). Standard WNE installations send received content through Ethernet 2 port on the EMR.
10. In order to distinguish between the different transmission standards, PAL (625) and NTSC (525), each format
exists on a separate multicast address. These are provided below:
Transmission paths multicast addresses
•
525 Satellite Transmission Path 224.14.14.14
•
625 Satellite Transmission Path 224.14.14.15
11. Select SkyCast from the Configuration menu in the left hand navigation menu. The Configuration - SkyCast
page will then be displayed.
12. Click Edit on the multicast IP address (224.14.14.14 or 224.14.14.15). The Edit SkyCast Rule page will be
displayed. Select the Forward and Ethernet2 options in the Action field for this multicast address.
Figure 9 SkyCast Rule for the EMR
13. Click Apply to designate that IP data should be sent to Ethernet 2 and confirm your SkyCast Rule settings.
14. Your IP data should now be being received and processed correctly.
You can verify data reception via the Network Interface Traffic and Statistics - Skycast pages. You can
access these pages by selecting the Network Interface or SkyCast options from the Statistics menu in the left
hand navigation bar.

15. Be sure to save all the configuration values you have just set to a configuration file! The process by which
to do this is described in the Saving a Configuration File section of this document.
Saving a configuration file
Once the EMR is correctly connected to the WNE signal, extracting IP data from the appropriate multicast address
and forwarding this IP data to Ethernet 2, this configuration should be saved as the default setting.

1.
Select Configuration File from the Maintenance menu in the left hand navigation bar. The MaintenanceConfiguration File page will be displayed.
Figure 12 Default configuration file for an EMR
Note: A default configuration file may already exist for this EMR. However, it is recommended that a new default file
be created with the settings you have just configured. This default profile will then be loaded whenever the EMR is
rebooted. In addition, if during the routine operation of your EMR, you or a Reuters support representative make
any changes to the configuration settings of the EMR, you should save these changes to the configuration file to
ensure that they are preserved whenever the EMR is rebooted.
2.
Set the following fields on the Maintenance-Configuration File page:
•
Enter a suitable name for this configuration in the Save current configuration as field.
•
It is recommended that you enter the date that the profile was created In the Configuration description
field.
•
Ensure that the Default option has been selected.
3.
Once these details have been entered, click Save to save this configuration.
4.
It is recommended that you now reboot the EMR to ensure that the configuration is loaded correctly upon startup.
5.
To reboot, select System Reboot from the Maintenance menu in the left hand navigation bar. A Reboot Now
button will be displayed. Click it. The EMR requires approximately 60 seconds to fully reboot and lock onto the
WNE signal.
You EMR configuration is now complete.
Note: If the configuration file is not correctly loaded when your EMR is rebooted, ensure that you have properly set
all your configuration settings and saved them to the configuration file or contact a Reuters support representative
for assistance.
Troubleshooting
Unable to lock to the WNE signal
Items to verify:
•
•
Verify the LNB values that have been entered (refer to Figures 7 & 8). Several WNE installations have
uncovered a different LNB value when examined by an engineer. For example, if it is believed that a 10GHz
LNB is installed, try altering the L-Band frequency value by ± 500MHz.
Check the quality of the RF coaxial cable connecting to the EMR. The F connector is a type of coaxial RF
connector commonly used for:
