1.4.1Front Panel
The front panel allows control using: four way touch pad, an Enter key, and an Esc key.
Operational commands and parameters are displayed on a graphical LCD. The four way touch pad
allows parameter modification and menu scrolling.
The F1 and F2 keys are short-cut keys, you can use them to perform the following tasks:
■ F1 is the Save/Drop key, use it from any screen or menu on the front panel.
■ F2 is currently active in DSNG modules only. The key sets the Carrier and Modulation Mode
parameters. For details see 3.1.1.1 Front Panel Controls and Displays on page 39.
Mechanical Structure
The alphanumeric touch pad offers an easy-to-use keyboard for using parameters that require
setting a number or a string of characters. The user can directly set values and strings with freetext using the alphanumeric touch pad.
For details on the touch-pad functionality and front panel components, see 3.1.1.1 Front Panel
Controls and Displays on page 39.
The front panel also contains warning and power/fail LEDs that operate as status indicators (see
3.1.1.1 Front Panel Controls and Displays on page 39).
The top line indicates the menu name. Up, Up/Down, and Down are displayed on the
top-right corner and indicate that up/down scrolling is possible.

1.4.2Ellipse Rear Panel
The Ellipse rear panel contains all required input and output connectors for the encoder
operation. The AC connector and power switch are also located on the rear panel. The different
Ellipse Series modules present various rear panels, as requirements of inputs and connectors vary.
The following images illustrate examples of rear panels. The related tables describe the
connectors on the panel.
The optional Audio Expansion Card provides the Ellipse 3000 with 8 pairs of stereo digital or
analog audio input ports. This card replaces the standard audio card with 2 pairs of stereo analog
or AES/EBU XLR audio input ports. Audio Expansion Card part no. 099-0547-001 supports audio
pass through.
This chapter provides detailed instructions for initialization and basic configuration in order to
activate the encoder.
It also provides step-by-step procedures for some of the more frequent set-up, configuration and
management activities required from the Ellipse operators.

several simultaneously http connections, there is a print: “multiple http connection”.
2.1.1Encoder and Modulator Status Monitoring
The Ellipse Status display enables the monitoring of the encoder streams’ parameters and the
current rate and operation mode of the modulator parameters.
For Ellipse 3200 DSNG model displays the configured Modulation and Carrier operation mode (on
or off) as well as the Symbol Rate and TX Frequency rates of the modulator.
NOTE: Although a DSNG unit can be equipped with either an IF modulator or an L-Band modulator, the
information displayed is generic and the parameters do not change; the only difference is in the values and
ranges. For an IF Up-Convertor, the screen specifies the IF Frequency value instead of TX Frequency value, given
for L-Band Modulator.

To monitor the Modulator Status on the front panel, check the Ellipse Idle screen (see the

Saving Configuration
Whether it’s entering new parameters through the front panel or submitting them through the
web, many Ellipse configuration procedures require saving.
Encoder configuration using the front panel changes can be saved within 60 seconds after the
most recent change. During these 60 seconds, the Ellipse control interfaces remind the user to
save with a blinking LED (the Warning LED) on the front panel and a shifting background for the
Save and Drop buttons in web-management.
When configuring the encoder from the front panel, the warning LED flashes green for 60 seconds
and if the changes are not saved within this time, they are automatically dropped, the LED stops
flashing and the encoder resets the changed parameters to their last-saved value. If the user sets
another parameter within this time, the count is reset and starts again.
However, in the web-management, the changes will sustain until the user either saves or drops
them.
For more details about saving procedures in the different control interfaces, see:
Chapter 2 Initial Configuration and Basic Operation
2.1.1.4Web Manager Save Procedure
Use the Save Changes button in the top part of the Explorer window to save any changes you
make.
Changes are reflected immediately in the web manager window but only occur in the encoder’s
operation after you save the new settings. After you make a change in the web manager, the Save Changes button flashes for a few seconds to indicate that you have unsaved changes.
For example, changing the Audio Encoding Scheme from MPEG-1 Layer 2 to Dolby® displays the
Dolby® sub-menus and specific parameters in the Explorer window. But the encoding affects the
audio encoding only after you click the Save Changes button.
Use the Drop Changes button to cancel recent configuration changes, returning the changed
parameters to their last-saved state. A pop-up message confirms that the changes have been
dropped.
Use the Refresh button to refresh the web page. This is useful for updating changes that were
configured on the front panel.
Web Configuration
NOTE: The Refresh button allows refreshing all parameter values displayed on the Web Manager. This is useful
for when a new configuration has been set and saved using the front panel.

2.2 Ellipse Set-Up Procedures
This section provides step-by-step instructions to perform some of the more frequent setup
functions of the Ellipse Series of Contribution Encoders.
NOTE: Each operation described in this section can be equally performed using the Ellipse front panel or the
Ellipse Web Manager user interfaces. Detailed information about the options provided on each front panel and
the respective web manager page are given in the detail operation chapters, starting from Chapter 4, and up in
this manual.
The following operational step-by-step procedures are detailed in this section:
■ H.264 Ultra Low Latency Mode Set-up Procedure
Setting up the output for low delay video stream, using the Ellipse Web Manager interface
(refer to Section 2.2.1.).
■ DVB-S2 L-Band Modulator Setup Procedure
Configuring the DVB-S2 L-Band modulator in the Ellipse 3200 encoder, using the Ellipse front
panel (refer to Section 2.2.2.).
Ellipse Set-Up Procedures
■ MPEG-2 Analog Transport Stream and VBI Configuration
Configuring the Ellipse encoder to receive and process an MPEG-2 analog standard definition
stream, using the Ellipse front panel interface, consists of the following main actions:
❑ Configuring video input parameters for the analog composite video received (refer to
Section 2.2.3.1.).
❑ Configuring video parameters for MPEG-2 standard definition processing (refer to
Section 2.2.3.2.).
❑ Setting a new service parameters (refer to Section 2.2.3.3.).
The receiving IRD should be set to Ultra Low latency mode. If the IRD receives IP stream from the
Ellipse, the IRD de-jitter buffer should be set to minimum.
To set-up the Ellipse to receive and process an ultra low latency H.264 transport stream:
1. Select Unit > Video in the web manager.
2. Select Sync to Video in the Sync Mode pull-down menu.
Ellipse Set-Up Procedures
3. Select an H.264 profile under Codec Profile.
