1 Introduction to Synapse
An Introduction to
Synapse
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 Broadcast Equipment
SA Website at http://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 rack controller manuals for a detailed description of the local
control panel, the way to set-up remote control over IP and for
frame related settin
g
s and status information.
Remote Control
Capabilities
The remote control options are explained in the rack controller
(RRC, RRS, ERC or ERS) manual. The method of connecting to a
computer usin
g
Ethernet is also described in these manuals.
! CHECK-OUT: “EVS CORTEX” SOFTWARE WILL
INCREASE SYSTEM FLEXIBILITY OF ONE OR
MORE SYNAPSE FRAMES
Although not required to use Cortex with a Synapse frame, you are
strongly advised to use a remote personal computer or laptop PC
with EVS Cortex installed, as this increases the ease of use and
understandin
g
of the modules.

2 Unpacking and Placement
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 from
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 card is essential as a card that is not located

3 A Quick Start
When Powering-
up
On powering up the Synapse frame, the card set will use basic data
and default initialisation settings. All LED’s will light during this
process. After initialisation, several LED’s 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 the EVS Cortex can be used to change
settings. An overview of the settings can be found in chapter 5, 6
and 7 of this manual.

EVS Cortex
Software
EVS 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. EVS 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 EVS Cortex, please refer to the Cortex help files.

5 Settings Menu
Introduction The settings menu displays the current state of each GDR416
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. Also the SCP08 control can be used.
Please refer to chapter 3 for information on the Synapse front panel
control and Cortex.
SYSTEM SETTINGS
Mode In the setting Mode you can select how you want to use the
GDR416: in a normal 4 x 3Gb DA mode or in a 4K mode. In the
4K mode, only the settings for input A are used and copied to all
other inputs (in other words: only PLL_set_A, Reclocker_A
and Mute_A are used; input B, C and D settings will be
automatically set to the settings of input A). Default is 4K.
PLL_set_A The GDR416 is capable of re-clocking a range of 3Gbit/s, HD and
SD SDI transport stream bitrates. PLL_Set_A is used to set input
A of the GDR416 to the correct bitrate of the incoming signal (if
mode is set to 4K, the PLL_Set_A will be copied to PLL_Set_B,
Cand Das well). PLL_Set_A can be set to Auto, 270 Mb/s,
1485 Mb/s and 2970 Mb/s. The default setting is Auto.
Reclocker_A The setting item Reclock_A determines if the incoming signal on
input A will be reclocked by the GDR416. The settings are:
■Auto: Auto selection between Bypass and Reclocked.
■Bypass: Does not re-clock the incoming signal
■On: The GDR416 always attempts to re-clock the input
The default setting is Auto.
Mute_A Mute_A enables input A of the GDR416 to be muted. The settings
of Mute_A are On, Off, Input Loss or PLL Unlock. Set to
Input Loss will mute input A only in case a carrier loss is
detected on input A. Set to PLL unlock will mute input A in case
the PLL rate of input A is not available. The Default setting is Off.

Note: If PLL_Set_# is set to 1485 or 2970 Mb/s it is possible that a
properly applied 270Mb/s signal (with a high signal strength and
low jitter) will pass through. However we do not advice to use this
situation because it could sometimes “miss-clock”.
When 270Mb/s signals need to pass, please set PLL_Set_# to
270Mb/s or set it to Auto.

7 Events Menu
Introduction An event is a special message that is generated on the card
asynchronously. This means that it is not the response to a request to
the card, but a spontaneous messa
g
e.
What is the Goal of
an event?
The goal of events is to inform the environment about a changing
condition on the card. A message may be broadcast to mark the change
in status. The message is volatile and cannot be retrieved from the
system after it has been broadcast. There are several means by which
the messa
g
e can be filtered.
Events The events reported by the GDR416 are as follows;
Announcements Announcements is not an event. This item is only used for
switchin

g
.
What information is
available in an
event?
The message consists of the following items;
1) A message string to show what has happened in text, for example:
“INP_LOSS”, “REF_LOSS”, “INP_RETURN”.
2) A tag that also shows what happens, but with a predefined number:
e.g. 1 (= loss of input), 2 (= loss of reference), 129(= 1+128 =
return of input). For a list of these predefined tags see the table on
the next page.
3) A priority that marks the importance of an event. This value is
defined by the user and can have any value between 1 and 255, or
0 when disabled.
4) A slot number of the source of this event.
The Message String The message string is defined in the card and is therefore fixed. It may
b
e used in controllin
g
software like S
y
napse Set-up to show the event.

INSTALLATION AND CONFIGURATION MANUAL
GDR416
18
The Tag The tag is also defined in the card. The tag has a fixed meaning. When
controlling or monitoring software should make decisions based on
events, it is easier to use the tag instead of interpreting a string. The
first implementation is the tag controlled switch in the GPI16. In cases
where the event marks a change to fault status (e.g. 1 for Loss of
Input) the complement is marked by the tag increased by 128 (80hex)
(e.
g
. 129 (81hex) for Return of Input).
