DVB+ Satellite Receiver: Overview
The Mainstream Data DVB+ Receiver, shown in Figure 1, tunes and demodulates a Digital
Video Broadcast-S, L-band RF signal input to provide data output. The DVB+ extracts IP
multicast packets from MPE sections and passes them out the Ethernet port based on the
authorized Program Identification Descriptions (PIDs) and multicast addresses. In addition, the
DVB+ can pass asynchronous output data through a standard serial port.
Note: Throughout this guide, the DVB+ Satellite Receiver is referred to simply as the “DVB+” or “the
receiver.”
Figure 1 The DVB+ SatelliteReceiver
Features of the DVB+ Satellite Receiver
Features of the DVB+ include the following:
•DVB-S compatibility
•40 Mbps of sustained throughput
•32 PID and 32 multicast address filtering
•Traditional Mainstream Data IDR support over DVB channels
•Configurable via front panel buttons and LCD, Web interface, or over-the-air network
download

2 MS4966 Rev 12
Safety Issues and Precautions
Protect yourself and help keep the DVB+ operating without disruption by following basic,
common sense procedures.
Do:
•Unplug power before changing external cables. This reduces the chance of electrical shorts
that could damage the receiver.
•Protect the DVB+ from liquids and excessive heat, humidity, or dust. These elements can
damage the processor electrical components.
•Connect the DVB+ only to grounded power outlets.
Do Not:
•Open the casework. Nothing inside the DVB+ is field-repairable. (Opening the case voids
the Mainstream Data equipment warranty.)
•Stack the receivers. Vents in the DVB+ casework are designed to provide the necessary
ventilation to the components. While the footpads on the receiver may help provide
sufficient space for ventilation, stacking is not recommended.
Documentation and Customer Support
This guide provides the high level information needed to understand the DVB+ Receiver in its
operational context. Site- or customer-specific information is not provided here. Typically a
Mainstream Data customer service representative or a network operator supplies the detailed
settings, procedures, and contact number for specific sites.

MS4966 Rev 1.2 3
Installing the DVB+ Satellite Receiver
This section summarizes the steps involved in setting up the DVB+ Satellite Receiver. After
cables are connected, you will need to verify or establish DVB+ settings through the front
panel LCD. This information is covered in the next section, “Understanding DVB+ Settings”
Note: If you do not yet know the expected Eb/N0reading and AGC levels for the site, contact the network
operator now.
Caution: Rain, snow, high winds, or extreme cloudiness can attenuate the signal. Try to avoid installing the
receiver during inclement weather, if possible, to minimize installation difficulties.
Before You Install the DVB+
Verify the following conditions:
1. A suitable satellite dish (with proper grounding) is already installed.
2. Coaxial cable is already run from the dish to the receiver location. (RG-6 cable is
recommended, length not to exceed 300 feet.)
3. RF coaxial cable shield is connected to earth ground with a #10 gauge (or heavier) solid
copper wire at the point of entry to the building.
4. RS-232 serial cable is shielded, with shield wire attached to connector shell at both ends
of the cable. Cable is “straight-through” (not NULL modem) if attaching directly to a PC
COM port.
5. Ethernet cables are of CAT-5 quality.
6. Power module is not yet connected to the DVB+.
Caution:: To prevent accidental shorts from causing circuit damage, the power module should always be
disconnected during installation or whenever cables are being changed.

4 MS4966 Rev 1.2
Step-by-Step Procedures
Installing and verifying DVB+ operation requires use of the LCD front panel. If you have not
previously installed Mainstream Data receivers or are unfamiliar with using the front panel, refer
to the next section, Understanding DVB Settings for the appropriate information on using the
panel.
Step 1: Connect the cables
1. Connect the coaxial cable to the RF Input connector.
2. Connect a RS-232 asynchronous cable to the Serial port to view traditional IDR-type
receiver data. (This port operates similarly to previous Mainstream Data IDR models.)
3. Connect an RJ-45 Cat-5 Ethernet cable to the DVB Channel port. This is the high-
speed connection delivering multicast content.
Note: If you are connecting directly to a PC instead of to a network hub, use the supplied cross-over
cable.
4. Connect an RJ-45 Cat-5 Ethernet cable to the Aux Channel port and to a PC if you
want to view or configure the DVB+ using a Web browser, such as Internet Explorer.
Note: If you are connecting directly to a PC, use the supplied cross-over cable.
5. Connect the power module to the DVB+ power input and to the power source.
Product of Mainstream Data, USA
This equipment complies with therequirements in
Part 15 of the FCC rules for a Class A computing
device. Operation of this equipment in a residential
area may cause unacceptable interference to radio or
television reception, requiring the operator to take
whatever steps are necessary to correct the situation.

On power-up, first the Power LED lights, then the remaining LEDs light and all flash once,
then the Power LED alone remains lit; simultaneously, a right and left LED in both the Aux
Channel and DVB Channel ports flash once. At power-up the port LEDs flash once: the left
LED means Link is UP; the right LED means Speed = 100Mbps.
When the DVB+ is booting, and during operation, the meaning of the right LED on each port
changes to indicate transfer (TX) activity.

MS4966 Rev 1.2 5
Step 2: Verify Initial Lock on Carrier
As soon as power is applied to the DVB+, an automatic self-test runs. The DVB+ then
attempts to locate and lock onto the preset carrier.
If a DVB carrier is not found the DVB+ toggles back and forth between the primary and the
alternate carrier until a lock is obtained on one of the channels. The receiver stores the last
known “good” channel carrier, and a subsequent reboot first tries to achieve lock on that
channel. If no alternate carrier has been specified in the receiver setup, the receiver attempts to
lock to the primary carrier until lock is achieved or the box is powered off.
To verify the receiver is locked to the preferred carrier, check the blue Lock LED on the front
panel and also the Show Status>Show Tuner Status LCD screens. Figure 3 shows the screen
location of the applicable status settings.

Step 3: Verify Signal Strength
Signal strength quality is indicated mainly by the Eb/N0reading in the Show Tuner Status
screen. It is possible to fine tune that reading by slightly adjusting the position of the satellite
dish. The Eb/N0should be at least 5.0, usually higher, depending on environmental conditions.
(Your site will have specific requirements.)
The AGC level indicates the signal strength at the input of the tuner and can be used to verify
that the cabling is complete and the LNB is getting power from the DVB+. The reading should
be within a range of 800 to 1020, with 1000 being typical. If the number is under 800, check the
coaxial cable connections and the LNB on the satellite dish.
Step 4: Call Customer Service for Network Download
If your DVB+ is designated for a network download, your customer service representative can
arrange for the Network Operations Center to download the appropriate configuration for your
site.
Once the Eb/N0 and AGC readings are at the expected levels and the Eb/N0 has been
maximized by adjusting the dish alignment, notify your customer service representative.
Your customer service representative may provide you with additional instructions following
the download.
Note: If the DVB+ was pre-configured at the factory, the necessary settings may already be established and do
not need to be downloaded. Verify this with your site coordinator.

MS4966 Rev 1.2 7
Step 5: Verify Data Output
If you are using the Serial port, you can verify its data output by performing various test
functions:
1. Request a test transfer from the NOC.
2. Connect the RS-232 cable to a computer and run Windows HyperTerminal to check
receiver settings.
3. Load a feed from a data provider to the test computer, and receive the file in
HyperTerminal.
To verify data output from the Aux and DVB Channels after cables are connected:
1. Check the link lights on the ports. The left indicator shows that the link is up, meaning
the Ethernet cable has properly connected; the right indicator shows transfer activity.
2. Check the Aux Channel port by setting up a connection between the receiver and a PC.
Set up a Web browser on the Aux Channel (see Using the Web Browser Interface) and
browse the DVB+ home page. (You need the IP addresses for both the receiver and the
PC to do this. Refer to the DVB+ View Aux LAN Setup LCD screen to view the IP
address of the receiver.) If necessary, “ping” the receiver to check that cable connection
is good.
3. Run a valid data feed through the DVB Channel Ethernet port while monitoring with a
suitable client PC application.
Corrective Actions and Status Monitoring
If data output through any of the channels is not as expected, first recheck the Eb/N0 and AGC
readings and then perform alignment corrections as needed.
Refer to the next section for descriptions of various status and setup LCD screens that provide
useful information: the Show Status>Show IDR Status screen, shows the critical statistics for
stat mux operation. The Show Status>Show IP Channel Status screens show the critical
statistics for multicast operation.
Step 6: Maintain the Equipment
Satellite transmission can be adversely affected by bad weather. High winds can knock a satellite
dish out of alignment, and heavy snows, rain, or cloud cover can severely diminish signal
quality. You, or another designated individual at your site, should attend to the following
maintenance activities:
•Check satellite dish alignment by monitoring the Eb/N0 following heavy or gusty winds.
•Remove snow from the satellite dish using a stiff whiskbroom.
•Make sure snow doesn’t accumulate on the dish and that the feedhorn window is clear.

MS4966 Rev 1.2 9
Understanding DVB+ Settings
All DVB+ receivers are pre-configured with a unique Ethernet MAC address and unique
Mainstream Data identification number, at a minimum. In addition, depending on specific
network or customer requirements, various features or services (other than the MAC address
and MSD ID) can be adjusted when the receiver is installed.
These factory settings can be changed after installation, in three ways or combinations thereof:
•Front panel with LCD display and pushbuttons
•Web browser interface
•Network download, using the optional NMS (a network-dependent option)
The DVB+ front panel is designed similarly to previous Mainstream Data receiver models;
current receiver users will be familiar with the 2-line display and tree structure of the menu
options. The front panel LCD and keypads are necessary at installation to set and achieve a lock
on the RF signal. Once the DVB+ is set up, subsequent configuration changes can be
downloaded from the Network Operations Center or entered through the Web browser
interface, as well as through the front panel.
Current settings can be viewed on the front panel or through the Web interface.
This section discusses how to use the front panel and the Web interface and how to interpret
the screens that are displayed.
Using the Front Panel
You can view and modify configuration settings, as well as view dynamic performance of the
DVB+ from the front panel LCD. Once you become familiar with the usage of the buttons,
this 20-character-by-2-line display provides a direct and intuitive interface to the DVB+
functions.

Front Panel Indicators
When power is first applied, the four indicators --- Power, Lock, Active, and Data--- flash
twice. The Power indicator stays lit while the DVB+ is booting. If signal lock has been
achieved, the Lock indicator stays lit.
The Active indicator is triggered when any valid packet is received from any PID. The Data
indicator lights when stat mux data is actually output through the Serial port or when DVB data
is output through the Ethernet port (Basically, the Active indicator shows that the DVB+ and
its satellite feed are functioning; the Data indicator shows that you are receiving usable data.)
LCD Screen
The Mainstream Data identification screen displayed after the receiver finishes its initial startup
procedure is the “home page” of the front panel. Pressing the SELECT button moves the
display to the first of four main stems of the menu “tree.” The four main stems are:

Figure 5 Top Level of Menu Tree
Navigating the Menu Tree
The front panel buttons are used for two functions: navigating the tree of screen displays and
entering new values:
•Press the SELECT button to drill down into the contents under either main stem.
•Use the left and right arrows to move within a stem.
•Press the CANCEL button to move back up towards the top of the tree.

MS4966 Rev 1.2 11
Entering and Changing Values
Some screens are designed for entering new values or for modifying existing values.
•Use the arrow buttons to increment or decrement the value displayed above the cursor.
•Press SELECT to advance the cursor to the right.
•Press CANCEL to move the cursor to the left.
Once the cursor is moved to the rightmost position, press SELECT again to store the value.
Invalid entries are not accepted by the DVB+. For example, if you try to enter the first byte of
an IP address as 257 (where the maximum allowable value is 255), the entry is rejected.
Overview of LCD Displays
Some LCD screens are static, meaning the screen is painted once upon entry and does not
change thereafter. However, some screens are dynamic, allowing variables, such as AGC, to be
observed in real time.
Note: Dynamic screens consume processor time, which reduces the available capacity for data processing.
Although the same current settings are displayed within the Specify Setup subordinate screens,
it is preferable to view the receiver setups only from the View Setup screens. An inadvertent
keystroke within Specify Setup could modify an important setting. Even more problematical,
features listed under Utilities usually place the receiver into a special mode, many of which can
disable data output.
Caution: Changes made within the Specify Setup and Utilities screens can disrupt system output.
