Synapse GXT100|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 10, "Status Menu" on
page 35 "Graphical User Interface" on page 1 and "Events Menu" on page 39.

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.

Block Schematic
Important Notice about Closed Captions
Historically, closed captions were transmitted in NTSC line 21, in accordance with EIA-608. This allows
two caption data bytes per field to be transmitted. With the introduction of HD and DTV, a new Closed
Caption specification was created, EIA-708. This allows more data to be sent per field, for extended
language, color support, PMT and EIT and timecode data.
The new DTV caption format cannot be translated back to EIA-608. However the EIA-708 may include
EIA-608 data as "NTSC closed captions", for compatibility with old decoders.
This card only de-embeds the NTSC closed captions, not the DTV closed captions. It will not function
with a DTV-only 708 closed-caption source.

5.1. Introduction
The Settings menu displays the current state of each GXT100 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), via GPI-triggers (GPI-A, GPI-B
or GPI-C) or by the input format on input 1 (SDI1-format) or input 2 (SDI2-
Format). 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_sel With this item you can select which input you want to use.
Can be SDI-1 (SDI input 1) or SDI-2 (SDI input 2). You can also choose a
Zoneplate or Colorbar as input. Set to Auto will automatically detect
which SDI input holds a valid input. If both inputs have a correct input,
SDI-1 will be chosen. The default for this setting is SDI-1.
