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 1.0.C

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 10, "Status Menu" on
page 19 "Graphical User Interface" on page 1 and "Events Menu" on page 24.

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.TheGMD100Card
Introduction
The GMD100 is a medium time 3Gb/s, HD and SD-SDI uncompressed baseband video delay. It can store
and delay SDI video. It can store and delay up to 8 seconds 3Gb/s and 16 seconds in HD and up to 64
seconds in SD.
One of the unique features is the capability of syncing a delay to the time code of the second input. An
example use of this card is when a video feed is sent down two separate paths or networks, and the
delay between the two is unknown. The card on each path would add the appropriate delay to its
incoming video to ensure that the output was co-timed. This co-timed output can for example be fed
into a backup switch and seamless switching with no time hops is achieved.
Features
•Autophaser and Framesync
•Adjustable offset delay up to
◦8 seconds 3Gb/s
◦16 seconds HD
◦64 seconds SD
•Adjustment in frames, lines and pixels
•Tracking audio delay with offset adjustment
•Adjustable full transparent delay mode for video, audio and ancillary data
•Locks
◦SDI input or reference
◦Possibility to add an offset to incoming video to match the offset timecode
•Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the
Ethernet port (ACP).
Applications
•Dynamic delay compensation for main/backup redundant path applications.
•Timing correction in 3Gb/s, HD and SD studios
•‘Late’ embedded audio correction (lipsync).

Dynamic Delay
The diagram below shows an example situation where the dynamic delay card is configured to ensure a
6 frame delay from the Reference Timecode.
1. The card will first sync the incoming video.
2. It will then compare the number of frames by which the incoming video is delayed against the
reference timecode. It will then delay the video by the correct number of frames to result in the
configured delay value.
The card will work in SD, HD and 3G mode. The input reference signal may not be in the same video
format as the input video signal (but would have the same frame rate), however both signals will include
a SMPTE 12M-2 ANC VITC time code (Time of Day).
For example, the reference time code may be SD, whereas the input video may be HD.
Losing timecode on main or tc-reference signal does not affect the output signal and the delay hold its
previous value.
Jump of the timecode is however not error free. The card will always try to follow the timecode read
from the inputs. On a short glitch within its range the card jumps to that location and back. There is no
filter or hysteresis on this logic.
The maximum video delay of the card in 1080i50 is 484 frames and the timecode measurements are
limited to + and -1000 frames. Timecode with a difference outside 484 frames gives a video delay of
484 frames but the audio delay can be up to the complete 1000 causing a lipsync issue. This is only
when the audio is de-embedded and embedded again. In full transparent mode the Audio Video delay
stays the same.
Outside the 1000 range the measurement is clipped to 1000. However as described above the audio and
video delay are not in sync.

5.1. Introduction
The Settings menu displays the current state of each GMD100 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.
All items preceded with a # sign are part of the presets.
5.2.SystemSettings
Setting Description
IO-Ctrl This card has separate presets for the input and output settings under
the ‘SYSTEM SETTINGS’ header. With this item you select how the IO
presets are controlled: manually (Manual) or via GPI-triggers (GPI-A, GPI-
B or GPI-C). By default it is set to Manual.
IO_Prst_Act With this item you can manually change the currently active IO settings.
Can be any preset between 1 and 16. By default it is set to 1. All menu
settings that are preceded by the # prefix under the ‘SYSTEM SETTINGS’
header are part of the preset.
IO_Prst_Edit Here you can select which of the 16 selectable IO settings presets you
want to edit. Changing this will not change the active preset, unless the
currently active preset is the one you are going to edit. All menu settings
that are preceded by the # prefix under the ‘SYSTEM SETTINGS’ header
are part of the preset.
PrstEditView With this setting set to Follow Active, the edit preset settings (e.g. UP_
Prst_editA and UP_Prst_editB) will follow the active preset when the
active preset is changed. This is to avoid confusion when changing the
active preset. Set to Independent, the edit preset will not automatically
follow active preset changes. By default set to Follow Active.

#V_delayA V-Delay setting allows adjustment of the vertical phase of the output
signal with respect to the selected reference input.
The V-Delay setting gives a delay in addition to the reference timing. For
example: if the V-Delay 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 1125 lines (dependent on I/O
format). The default setting is 0ln. The preset master for this is Out-Frmt,
hence the # prefix.
#H_delayA The H-Delay setting allows adjustment of the Horizontal phase of the
output signal with respect to the selected reference input.
The H-Delay setting gives a delay in addition to the reference timing. For
example: if the H-Delay 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 5124 pixels (dependent on I/O format). The
default setting is 0px. The preset master for this is Out-Frmt, hence the #
prefix.
#F_delayA_AlignA This setting sets the timecode type to be used for delay alignment.
Default is off. Setting can be set to Off, VITC, ATC or both.
#TC_Align_SetA The TC_Align_SetA allows correction of the delay of the card according
to the timecode measurement difference of the selected channel A and
B. Modes are Off, Auto, Once and Hold.
When set to Off, the additional delay is set to 0 and the Add-Delay_
Range status is set to OK.
In Auto, the delay continually tracks the difference in timecode of video
channels A and B. The Add-Delay_Range status indicates if the additional
delay is within range.
When set to Once, the delay is set once on the rising edge of this signal
with the difference in timecode of video channel A and B. If you want to
reset the value, the setting must be changed to Hold and then back to
Once.
In Hold the additional delay is fixed and not updated anymore. The Add-
Delay_Range status still indicates if the additional delay is within range.
Hold is often used in combination with Once.
#F_Align_StepA This setting selects the amount of frames that will be counted before a
frame delay step of the new frame delay is realized. For example, if the
old delay is 100 frames and the new delay is 200 frames and this setting
is set to 2. The new delay increases each frame from 100, 100, 101, 101,
102, 102, etc. until 200. Range is 0fr..1000fr. Default is 0, which results in
an immediate response.
