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.
Please refer to "Appendix 2: Card Dip Switches for BHX and Fiber Configurations" on page 38
before connecting any back panel.
2| November 2021 | Issue 1.00.E

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 24 "Graphical User Interface" on page 1 and "Events Menu" on page 28.

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.The2GF100-110Card
Introduction
The 2GF100-110 is a dual channel frame synchronizer with backup inputs and 8 channel audio
transparency and color correcting capabilities. The powerful matrix multiplexer can feed audio from the
embedded domain into the Synapse bus to an ADD-ON card like the DIO48. This matrix multiplexer also
allows for audio to be inserted from the ADD-ON bus into the embedded domain of the 2GF100-110. The
2GF110 adds a full audio shuffler and audio proc-amp with gain and phase control.
The 2GF100/110 also allows you to swap timecode data from channel one to channel two or vice versa,
where the delay timing of the timecode is copied from the source channel.
The 2GF100/110 is compatible with 270Mb/s, 1.5Gb/s and 3Gb/s for full 1080p/50 or 1080p/59.94 use.

•Transparent for 8 channels of embedded audio per channel
•Embedded domain cross input audio shuffling, gain and phase control (110 only)
•Embedding and de-embedding through Synapse bus
•Video proc-amp (Y and C control)
•Color corrector (RGB and total gain, RGB and total black)
•Hue control for NTSC inputs
•Locks to a Bi-Level or a Tri-level sync, or to an SDI input.
•Full control and status monitoring through the Ethernet port (ACP).
The frame synchronizer works best if the inputs are switched according the SMPTE guidelines
described in RP168.
This ensures that not only the picture but also the ancillary data remains correct. The frame
synchronizer however can handle complete asynchronous switching at the input.
To ensure correct operation, the F-delay of the card needs to be 1 or higher to allow enough
time to mask the error.

•B Only: Channel B to all outputs
When in ‘A only’ or ‘B only’ modes, you can process 16 channels of audio for the outputs.
When in mixed modes, you can process only 8 channels of audio per input.
Also when in ‘A only’ all the settings that involve video channel B are discarded and when in
‘B only’ all channel A settings are discarded.
10| November 2021 | Issue 1.00.E

#Switch-Back When this setting is set to on, the input selection will switch when the
active input is lost. Set to off will not switch the input on input loss. Set to
once, the switch will only be done once, and will not switch back when
the input fails again. Default is on.
#F_delay F-Delay sets the number of delayed Frames. The available range is from
0 to 250 fields (dependent on the I/O). Default is 0F. The preset master
for this is Out-Frmt, hence the # prefix.
#V_delay 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_delay 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.
#Freeze_A Freeze enables the capture of one Video Field or Frame (depending on
the setting Freeze_Mode). The settings for Freeze are On or Off. The
default is Off.
#Freeze_B Freeze_B enables the capture of one Video Field or Frame (depending on
the setting Freeze_Mode) for outputs B. The settings for Freeze are On
or Off. The default is Off.
Delay-Status It is possible to display the processing time of the card in the Status
menu. This setting allows you to switch this function On or Off (default).
Lock-Mode Lock-Mode determines whether the card is locked to its input , to the
reference (Ref1 or Ref2) or freerun (not locked). Can also be set to
RefAuto. By default it is set to Ref1.
When set to RefAuto the card chooses ref1 as its source. Whenever ref1
fails, it will switch to ref 2 (only for SFR08 and SFR18 frames and only
when ref2 offers the same ref format as ref 1). When ref 1 is back up
again, it will only automatically switch back to ref 1 when ref 2 fails.
INSTALLATION AND OPERATION MANUAL
Synapse 2GF100 - 2GF110|5. Settings Menu| 11

Ref-Type Sets the type of incoming reference. Can be either Bi-Level (default) or
Tri- Level.
P60-P50_Sync With this setting you can choose to synchronize each one frame or each
two frames. Default is One Frame. The two-frame-synchronize mode
only works for 720p60, 720p50, 1080p50 and 1080p60 standards.
ANC_BlankA With this setting you can Blank the vertical ancillary data only (V-Only),
blank the horizontal ancillary data only (H-only) or blank both vertical and
horizontal ancillary data (H_And_V). You can also choose to not blank any
data (Off), which is also default.
ANC_BlankB With this setting you can Blank the vertical ancillary data only (V-Only),
blank the horizontal ancillary data only (H-only) or blank both vertical and
horizontal ancillary data (H_And_V). You can also choose to not blank any
data (Off), which is also default. This setting is for Channel B only.
Freeze_Mode Freeze_Mode allows you to choose between storing a complete Video
Frame or Field (double written) in case of a video freeze. The default
setting is Field.
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.
PatternSpeed Sets the speed of the test-pattern (see settings Inp_SelA and Inp_SelB)
animation between 0 (still) and 15 (fast). Default is 1.
Input_Loss_A Input_loss_A determines what the output of outputs A is in case of lost
input:
•Freeze: a capture of the last good field or frame.
•Colorbar: a color bar
•Zoneplate: a zone plate
•Black: a black output.
•Grey: a gray output.
•Green: a green output.
•Freeze 1 sec: a freeze of the last field or frame for 1 second. After 1
second the output framework is disabled.
•Freeze 5 sec: Same as Freeze 1 sec, only holding the freeze
frame/field for 5 seconds.
The default setting is Freeze.
Input_Loss_B Input_loss_B determines what the output of output B is in case of lost
input. Same values as Input_Loss_A are possible.
