INSTALLATION AND OPERATION MANUAL
Synapse UXU400|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.
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 40.
Front Panel Control
Front Panel Display and Cursor
Settings are displayed and changed as follows:
Use the cursor ‘arrows’ on the front panel to select the menu and parameter to be displayed and/or
changed.
Move forward through the menu structure.
Go back through the menu structure.
Move up within a menu, or increase the value of a parameter.
Move down through a menu or decrease the value of a parameter.
When editing parameters, pressing ► twice will reset the value to its default setting.

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.TheUXU400Card
Introduction
The UXU400 is a high-end up/down/cross converter. Based on EVS's Motion Optimized Quality De-
interlacer (MOQD) and extensively computer-optimized scaling and filter algorithms, the new 400 series
of up/down/cross converters ensure the absolute best quality video conversion from any standard to
any standard within the same framerate. The card allows you to simulcast any output standard in any
format from any source standard.
The embedded audio is carried over to the SD, HD or 3Gb/s domain. The appropriate aspect ratio can be
applied by control of VI, WSS and GPI inputs by use of 16 presets per output that can store the aspect
ratio conversions.
Also included is a 4K 4-wire interface. The UXU400can up and down convert to and from 4K
(3840x2160).
The UXU400 offers a LUT-based color space and dynamic range conversion. The LUT can be stored on
16 presets and selected on the fly. The unit is compatible with standard LUT tables in either 1D or 3D
format.
This topology offers you the possibility of three fully preset-based methods across modes:
1 YCrCb to RGB > 1D LUT > RGB to YCrCb
2 YCrCb to RGB > 3D LUT > RGB to YCrCb
3 YCrCb to RGB > 1D LUT > Matrix > 1D LUT > RGB to YCrCb
Features
•LUT-based Color space and Dynamic range conversion.
•16 LUT presets for standard LUT tables (.cube, .LUT, .txt).
•1D LUT 10bits 1024 RGB values (1024x3 rows).
•3D LUT 10bits 35.937 RGB values (33x33x33).
•Side-by-side split screen mode with slider for evaluation of LUT.
•LUT bypass mode.
•Compatible with ITU-R BT709 and ITU-R BT.2020 I/O (conversion matrix from YCrCb to RGB and
back).
6| November 2021 | Issue 1.00.C
•Industry highest quality de-interlacing algorithm, using EVS's MOQD.

Important Notice about Closed Captions
Historically, closed captions were transmitted in NTSC line 21 according to EIA-CEA-608-B (bit rate
960b/s). This allowed two caption data bytes per field to be transmitted. With the introduction of HD and
3Gb/s the new EIA-708-B Closed Caption standard was created, which sends closed caption data in
DTVCC packets. This allows more data to be sent per field (bit rate 9600b/s) for extended language,
color support, PMT and EIT and timecode data.
Besides the new DTVCC packets, the EIA-708-B caption stream may also include EIA-CEA-608-B data
bytes which are stored as NTSC compatibility bytes for compatibility with old decoders.
EIA-CEA-608-B Transparency
This card is fully transparent to EIA-CEA-608-B caption streams.
EIA-CEA-608-B to EIA-708-B Translation
For EIA-CEA-608-B to EIA-708-B translation, the EIA-CEA-608-B bytes will be mapped on-one-on to
the NTSC compatibility bytes. Furthermore, the EIA-CEA-608-B bytes will be remapped to DTVCC
packets.
EIA-708-B to EIA-CEA-608-B Translations
There are EIA-708-B DTVCC captions which are not translatable to EIA-CEA-608-B. Therefore the
NTSC compatibility bytes will be used for EIA-708-B to EIA-CEA-608-B translation. So the DTVCC
packets from the input will be ignored.
INSTALLATION AND OPERATION MANUAL
Synapse UXU400|4. The UXU400 Card| 9
EIA-708-B Transparency
This card is not fully transparent to EIA-708-B caption streams. The NTSC compatibility bytes are
transparent, but the DTVCC packets are regenerated from the NTSC compatibility bytes. So the DTVCC
packets from the input will be ignored.
EIA-708-B DTVCC output caption data only supports EIA-CEA-608-B translation of the
primary language (CC1).
CC2 to CC4, T1 to T4 and XDS translations are not supported.

5.3.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.
