Synapse GFS100|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) manual. The method for connecting to a computer using Ethernet is described in the RRC/RRS
manual.
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 35
before connecting any back panel.
2| November 2021 | Issue 1.00.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.
Changing Settings and Parameters
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 "Graphical User Interface" on page 1 and
"Events Menu" on page 24.

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.

4.TheGFS100-110Card
Introduction
The GFS100-110 is a frame synchronizer with backup inputs and 16 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 GFS100-110. The GFS110 adds a full
audio shuffler and audio proc-amp with gain and phase control.
The GFS100-110 is compatible with 270Mb/s, 1.5Gb/s and 3Gb/s for full 1080p/50 or 1080p/59.94 use.
Features
•3 inputs: 2 SDI and 1 composite.
•Handles complete asynchronous switching at the input
•Compatible with the following input formats (auto-selecting): 1080p59.94/50/25/24, 1080i59.94/50,
720p59.94/50, SD525/626.
•Frame sync with output phase control in Frames, Lines and pixels with respect to reference. Delay
setting are stored per output format for a constant latency operation.
◦30 Frames delay offset (per channel) for all 1080 formats
◦60 Frames delay offset (per channel) for all 720 formats
◦125 Frames delay offset (per channel) for all SD formats
•5 GPI inputs assignable to different preset banks
◦Input selection
◦Audio shuffling, gain and phase (110 only)
•Color corrector
•Transparent for 16 channels of embedded audio
•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)
•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 front panel of the SFR04/SFR08/SFR18 frame and the
Ethernet port (ACP)
6| November 2021 | Issue 1.00.C
The frame synchronizer works at 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 so there is enough
time to mask the error.
Applications
GFS100-GFS110:
•Transmission output frame synchronizer with backup input.
•General purpose post-router autophaser.
GFS110 only:
•Combining embedded audio channels of 2 inputs into 1.

5.SettingsMenu
Introduction
The Settings menu displays the current state of each GFS100/110 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.
5.1. 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, 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.
#Inp_SelA With this item you can select which input you want to use for ChannelA.
Can be SDI-1 (SDI input 1), SDI-2 (SDI input 2) or Analog (CVBS in). You
can also choose a Zoneplate or Colorbar as input. Can also be set to Off
to switch off ChannelA entirely. The default for this setting is SDI-1.
8| November 2021 | Issue 1.00.C
#CVBS-Frmt With this item you can set the format of the CVBS input. Possible formats
to select here are (default is Auto):
•PAL-M
•PAL-N
•NTSC-M
•NTSC-4.43
•NTSC-J
•SECAM
•PAL-60
•PAL-BGHID
•Auto (automatic detection and selection between NTSC-J and PAL-
BGHID)
#Out-Frmt With Out-Frmt you can set what the output should be of channel A as
well as channel B. Possible settings are:
•1080i60 (default) •1080i50
•1080p60 •1080p50 •1080p30
•1080p25 •1080p24 •1080p24sf
•720p60 •720p50
•SD525 •SD625
•AutoA, sets the output format automatically according to what has
been detected).
#IO-Map With this setting you can select the 3Gb/s mapping in case the input
format is 1080p50 or 1080p60. Can be manually set to Level A (default)
or Level B. You can also choose to set it to auto, in which case the GDL
will automatically detect whether the input is Level A or Level B.
#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.
INSTALLATION AND OPERATION MANUAL
Synapse GFS100|5. Settings Menu| 9
#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.
Delay-Status It is possible to display (in the IODelayA and IODelayB) 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 input 1), 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.
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.
10| November 2021 | Issue 1.00.C
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.
5.2.Inserter
This card can insert several data values in the VBI of the outputs. With the following settings you can
choose what you want to insert.
SMPTEST352 Payload Identifier
The SMPTE ST 352 Video Payload Identifier, also known as VPID, is transported within the ancillary data
of an SDI stream. The ancillary packet is placed in the HANC space. This packet contains 4 bytes of
data.
There are two versions of the standard. The first was published in 2011 and the second in 2013. The
revision can be seen within the 4 bytes.
When the GFS100 is not processing the incoming VPID packets, they will be passed transparently. When
it generates the packets, the GFS100 will output VPID packets using the 2013 standard.
INSTALLATION AND OPERATION MANUAL
Synapse GFS100|5. Settings Menu| 11
Setting Description
S352_Insert S352_Insert enables the Video Payload Identifier insertion in the HANC
space. It enables the user to insert or passthrough (On) the S352 Dynamic
range and colorspace payload. When this menu item is set to On (default), it
will generate a SMPTE ST352-2013 packet and overwrite the existing one
(for both Luminance and Chrominance).When it is set to Off, it will pass the
packet to the output as-is (only on Luminance).In HD 1080i for ATC-LTC
transparency, the user may switch it Off to pass the ATC-LTC HANC
packet on line 10.
Output-Matrix This setting will only work if S352_Insert is set to On. It enables you to set
the colorspace in REC709 (default) or REC2020. When set to either REC709
or REC2020, the S352 data is included in the s352 packet. (This does not
change anything in the picture.)
HDR_Curve_Out The dynamic range is the range of information between the lightest and
darkest part of an image, also known as an image’s luminosity. This setting
enables you to set the dynamic range in standard dynamic range SDR
(default), HLG, PQ or SLOG3. With all of these settings, the S352 data is
included in the S352 packet. (This does not change anything in the
picture.)
Bit_Depth_Out Bit depth is the range of bits being used. This setting enables you to set the
bit depth to Narrow (8bits) or Full (10bits). When set to either Narrow
(default) or Full, it includes this data in the S352packet. (This does not
change anything in the picture.)
S2016-Line With this setting you select a line in the VBI to where the AFD (SMPTE 2016)
data should be written. Lines 0 till 31 are selectable. By default it is set to
line 17.
Timecode_ins Here you can set if the timecode on the inputs should be copied to the
outputs (On), or to copy the timecode from input 1 to input 2 (Copy 1 => 2),
or to copy the timecode from input 2 to input 1 (Copy 2 => 1). You can also
turn Off timecode insertion.
Default is On.
VITC_Ln_In With this setting you can select what line of the input you want to copy the
VITC data from (only when input is SD). Can be any line between line 7 and
line 22. Default is line 19.
VITC_Ln_Ctrl Here you can choose whether you want to select the line, to where you
want to copy the timecode data to, manually (manual) or use the
information in the ATC_DBB package to select the lines (ATC_DBB package
contains information about the line duplication as well). Default is Manual.
VITC_Ln_625 When VITC_Ln_Ctrl is set to Manual, with this setting you can select a line
between 7 and 22 when the output is SD625. Default is line 19.
VITC_Ln_525 When VITC_Ln_Ctrl is set to Manual, with this setting you can select a line
between 7 and 22 when the output is SD525. Default is line 10.
