Synapse GED100|What's New?| v
1. Introduction
Synapse is a modular system designed for the broadcast industry. High density, intuitive operation and
high-quality processing are key features of this system. Synapse offers a full range of converters and
processing modules. Please visit the EVS website at www.evs.com to obtain the latest information on
our new products and updates.
Local Control Panel
The local control panel gives access to all adjustable parameters and provides status information for any
of the cards in the Synapse frame, including the Synapse rack controller. The local control panel is also
used to back-up and restore card settings. Please refer to the RRC18, RRC10, RRC04, RRS18 and RRS04
manuals for a detailed description of the local control panel, the way to set up remote control over IP and
for frame-related settings and status information.
Remote Control Capabilities
The remote-control options are explained in the rack controller (RRC18 / RRC10 / RRC04 / RRS18 / RRS04
/ ERC108-118 / ERS108-118) manuals. The method for connecting to a computer using Ethernet is also
described in the ERC/ERS/RRC/RRS manuals.
Cortex software will increase system flexibility of one or more Synapse frames.
Although it is not required to use Cortex with a Synapse frame, you are strongly advised to use a remote
personal computer or laptop PC with Cortex installed, as this increases the ease of use and
understanding of the modules.

2.UnpackingandPlacement
Unpacking
The EVS Synapse card must be unpacked in an anti-static environment. Care must be taken NOT to
touch components on the card – always handle the card carefully by the edges. The card must be stored
and shipped in anti-static packaging. Ensuring that these precautions are followed will prevent
premature failure of components mounted on the board.
Placing the Card
The Synapse card can be placed vertically in an SFR18 frame or horizontally in an SFR04 and SFR08
frame. Locate the two guide slots to be used, slide in the mounted circuit board, and push it firmly to
locate the connectors.
Correct insertion of the card is essential, as a card that is not located properly may show valid indicators,
but will not function correctly.
On power up, all LEDs will light up for a few seconds.This is the time it takes to initialize the
card.
2| November 2021 | Issue 1.00.B
3.QuickStart
Powering Up
On powering up the Synapse frame, the card set will use basic data and default initialization settings. All
LEDs will light up during this process. After initialization, several LEDs will remain lit – the exact number
and configuration is dependent upon the number of inputs connected and the status of the inputs.
3.1. ChangingSettingsandParameters
The front panel controls or Cortex can be used to change the settings. An overview of the settings can
be found in later chapters of this manual. Please refer to "Settings Menu" on page 9, "Status Menu" on
page 40 "Graphical User Interface" on page 1 and "Events Menu" on page 45.

3.2.UsingCortexwithSynapse
EVS Cortex Software
Cortex can be used to change the settings of Synapse modules from a PC, either locally or remotely. The
software enables communication based on TCP/IP between the Setup PC and Synapse
frames/modules.
Each Synapse frame is addressed through its rack controller’s unique IP address, giving access to each
module, its menus and adjustment items. Cortex has access to data contained within the Synapse
module and displays it on a GUI. The software has an intuitive structure following that of the module that
it is controlling.
For operation of Cortex, please refer to the Cortex help files.
Further information about Front Panel Control and Cortex can be obtained from the ERC, ERS,
RRC and RRS operational manuals and the Cortex help files.

4.TheGED100Card
Introduction
The GED100 is an embedded domain Dolby E to Dolby Digital or Dolby Digital (Plus) transcoder. It
enables simultaneous encoding of 5.1+2.0 or 4 individual stereo channels (languages) to 4 Dolby Digital
(Plus) 2.0 streams.
The new Quad Speed audio bus allows for implementation of ‘in between’ audio processing. This means
that we can stream the decoded Dolby E audio to a Quad Speed Audio ADD-ON card such as the DLA44
or DLA42, process this audio and send it back to the GED100 for encoding into Dolby Digital or Dolby
Digital plus.
The ADD-ON card theoretically does not need a connector panel (besides the metadata input) and all
audio routing is performed inside the Synapse frame by just placing these cards in adjacent slots.
Features
•Dolby E decoding (no Dolby Digital Decoding)
•Encoding of up to 4 times 2.0 Dolby Digital (Plus) outputs, or 5.1 Dolby Digital (Plus) + 2.0 Dolby
Digital (Plus)

5.SettingsMenu
5.1. Introduction
The Settings menu displays the current state of each GED100 setting and allows you to change or adjust
it.
Settings can be changed using the front panel of the Synapse frame (SFR18, SFR08 or SFR04) or with
Cortex. The SCP08 control can also be used. Please refer to "Quick Start" on page 3 for information on
the Synapse front panel control and Cortex.
5.2.Video
Setting Description
Input-Select With this setting you can select which SDI input you would like to use for
Dolby processing. You can choose between SDI1 or SDI2. Can also be set
to Auto, which automatically chooses the valid SDI input (with SDI 1 as
priority).
Switch-Back When Input-Select is set to Auto and SDI1 fails, the card will
automatically switch to SDI2. When the setting Switch-Back is set to On,
the selected input is set back to SDI1 when SDI1 is valid again. When set
to off, it will remain on SDI2 until it is changed manually or when SDI2
fails.
Lock-Mode With this setting you select what the card should lock itself to: SDI1, SDI2,
Ref1 or Ref2. When set to Ref1 or Ref2 (i.e. one of the frame’s reference
inputs), there will be an autophaser active for the audio, but not a
framesynch for the video! Can also be set to Auto-SDI, which locks to the
currently selected SDI input. Default is SDI1.
Out-Frmt With Out-Frmt you can set what the output should be. This setting is only
used for the delay options. This will not up/down/cross convert your
input signal. Possible settings are:
•1080i60 •1080i50
•1080p60 •1080p50 •1080p30
•1080p25 •1080p24
•720p60 •720p50
•SD525 •SD625
•Auto (default), sets the output format automatically according to
what has been detected).
INSTALLATION AND OPERATION MANUAL
Synapse GED100|5. Settings Menu| 9
Phaser1-Offset The timing or offset of the autophaser of SDI Input 1 can be tuned with
Phaser1-Offset (see block schematic) between 0 and 4124px. Default is
0px.
The correct functioning of the autophaser can be checked using status-
items Phaser1_H_Pos and Phaser1_Stat. When Phaser1_Stat shows Safe,
the autophaser is working in its Safe-region. When Phaser1_Stat shows
Warning or Critical, the Phaser1_Offset setting can be used to tune the
autophaser into its Safe -region.
The autophaser is enabled when the Lock-Mode is set to Ref1 or Ref2
and when a Ref is present, shown by the status-item Ref-Format.
Phaser2-Offset The timing or offset of the autophaser of SDI Input 2 can be tuned with
Phaser2-Offset (see block schematic) between 0 and 4124px. Default is
0px.
Correct functioning of the autophaser can be checked using the
Phaser2_H_Pos and Phaser2_Stat status items. When Phaser2_Stat
shows Safe, the autophaser is working in its Safe-region. When Phaser2_
Stat shows Warning or Critical, the setting Phaser2_Offset can be used
to tune the autophaser into its Safe region.
The autophaser is enabled when the setting Lock-Mode is set to Ref1 or
Ref2 and when a Ref is present, shown by the Ref-Format status item.
Phaser-Status It is possible to display the function of the autophasers in the status
menu of the card. This setting enables or disables the status-items:
Phaser1_H_Pos, Phaser2_H_Pos, Phaser1_Stat and Phaser2_Stat. Default
setting is Off.
5.3.Delay
Setting Description
Delay-Bypass You can bypass the delay block entirely by setting this to on. By default it is switched
off.
Delay-mode_1 With this setting you decide whether the card should apply delay by means of time in
milliseconds (defined with Time-Delay_1) or to apply delay by means of frames, lines
and pixels (Fr-Ln-Px). Default is Fr-Ln-Px.
Time-Delay_1 This setting is only used when Delay-mode_1 is set to Time. It defines the delay that
should be applied to the video in milliseconds between 0 and 10000ms.
F-Delay_1 F-Delay sets the amount of delayed Frames. The available range is from 0 to 250
frames (dependent on the video format).When Out-Frmt is SD, the maximum is 250
frames, when it is 720p50/60 the maximum is 120 frames. All other HD formats can be
delayed a maximum of 60 frames.
10| November 2021 | Issue 1.00.B
V-Delay_1 V-Delay_1 setting allows adjustment of the vertical phase of the output signal with
respect to the selected reference input.
The V-Delay_1 setting gives a delay in addition to the reference timing. For example: if
V-Delay_1 is set to 10 TV HD lines, the output signal will be delayed by reference
timing + 10 TV HD lines. The signal is delayed (advanced) with respect to the phase of
the reference signal. The available range is from 0 to a maximum of 1124 lines
(dependent on the video format). The default setting is 0ln.
H-Delay_1 The H-Delay_1 setting allows adjustment of the Horizontal phase of the output signal
with respect to the selected reference input.
The H- Delay_1 setting gives a delay in addition to the reference timing. For example,
if H-Delay_1 is set to 10 pixels, the output signal will be delayed by reference timing +
10 pixels. The signal is delayed (advanced) with respect to the phase of the reference
signal. The available range is from 0 to a maximum of 4124 pixels (dependent on the
video format). The default setting is 0px.
Delay-Status It is possible to display (in the status menu IODelay_1) the processing time of the card
in the status menu. This setting allows you to switch this function On or Off. Default
setting is Off.
5.4.Preset
Setting Description
Control With this setting you decide whether you want to manually change the presets,
change preset via the GPI contacts or change it by signal loss detection (see
LossDetect setting). A combination of GPI contact overrides together with loss
detection is also possible. GPI+LossDetect only works in non-latch mode. Default is
manual.
INSTALLATION AND OPERATION MANUAL
Synapse GED100|5. Settings Menu| 11
GPI-Ctrl The GED100 has several physical GPI contacts to control the card’s presets (if
presets are set to be GPI controlled).
Latch: Latching GPI mode. When a contact is closed momentarily (edge triggered).
Non-Latch: Non-latching GPI mode. When a contact is closed all the time (level
triggered).
BCD: Binary GPI mode. GPI contacts work as shown in the following table:
GPI 3 GPI 2 GPI 1 Activate Preset
0 0 0 No change
0 0 1 Preset 1
0 1 0 Preset 2
0 1 1 Preset 3
1 0 0 Preset 4
1 0 1 Preset 5
1 1 0 Preset 6
1 1 1 Preset 7
Ext-Mode With this item you set the purpose of pins 5 through 8 of the RJ45 connector on the
backpanel. The pupose can be either additional GPIO contacts (resulting in 7 GPI
contacts instead of 3) or to use these pins as a Dolby metadata I/O. Default is GPIO.
LossDetect With this setting you can set which source should be checked for the LossDetect
function (see settings Control and MD-control). When the here-set-source is lost, the
card will switch to the preset set with the Loss setting. When the source returns, the
card will switch to the preset set with the Detect setting.
Sources which can be checked on are DolbyE,S2020-SDI,MD-LocalIn (local
metadata input) or DolbyDigital(+). Default is DolbyE.
The aforementioned Dolby sources are detected sources and are not necessarily supported
by embedded Dolby encoders or decoders.
If LossDetect is being used, the #Emb-Mode and #Emb_A_Sel ~ #Emb_D_Sel settings need
to have the same values for both “loss” and “detect” presets to circumvent ‘reset’ of the
embedders.
This can result in Dolby and/or PCM CRC errors at the output of the embedders. If one of
these values changes, a reset is needed to guarantee audio-phase alignment for all
embedder outputs!
Loss Here you select to which of the 7 presets the card should switch in case the source
set with LossDetect is lost. When set to off, the card will not switch presets when a
loss is detected. Default is off.
