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 8, "Status Menu" on
page 12 "Graphical User Interface" on page 1 and "Events Menu" on page 13.

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.

5.1. Introduction
The Settings menu displays the current state of each U4D100 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_Prst_Act With this item you can manually change the currently active IO settings.
Can be any preset between 1 and 8. By default it is set to 1. All menu
settings that are preceded by the # prefix are part of the preset except
for the anaglyph mode presets.
IO_Prst_Edit Here you can select which of the 8 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 are part of the preset except for the
anaglyph mode presets.
#Out-Frmt With Out-Frmt you can set what the output should be. Possible settings
are:
•1080i60 •1080i50
•1080p60 (default) •1080p50 •1080p30
•1080p25
•Auto, sets the output format automatically according to what has
been detected).
#Output_Map With this setting you can select the 3Gb/s mapping in case output B
format is 1080p50 or 1080p60. Can be manually set to Level A or Level B.
8| November 2021 | Issue 1.00.B

#Mode The Mode setting determines if the output signal is down converted or
the input is passed to the output. Settings are:
•Pass (Default)
•Down.
#H-Sharpness With H-Sharpness you can select how much detail enhancement you
want to add. Ranges from 0% to 100%. The Default is 0%.
#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.
#V_delay The 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 1124 lines. The default setting
is 0ln.
#F_delay F-Delay sets the amount of delayed Frames. The available range is from
0 to 7 frames. Default is 0F.
#OSD-Style Selects the style of the On Screen Display text. The following are
possible:
Off
Transp: Enables the text in transparent mode.
Masked: Enables the text in masked mode.
Blink-Transp: Blinks the text in transparent mode.
Blink-Masked: Blinks the text in masked mode.
#Vert-AA-Filt The vertical anti-aliasing filter enables you to minimize distortion artifacts
to give lines a smoother appearance. Options are 0 through 7. Default is
4.
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). By default it is set to
Ref1.

Ref-Type Sets the type of incoming reference. Can be either Bi-Level (default) or
Tri- Level.
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).
SMPTE ST 352 Video 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 U4D100 is not processing the incoming VPID packets, they will be passed transparently. When
it generates the packets, the U4D100 will output VPID packets using the 2013 standard.
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 S352packet. (This does not
change anything in the picture.)
Gain With this setting you control the overall gain of the video of channel B
between 50 and 150%. Default is 100%.
R-Gain R-GainB controls the Red gain of channel B. The control range is
between 50% and 150%. The default setting is 100%.
