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 RRC18, RRC10, RRC04, RRS4, RRS18 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/RRS04/RRS18) manual. The method of
connection to a computer using Ethernet is described in the RRC
manual.
! CHECK-OUT: “SYNAPSE CORTEX” SOFTWARE
WILL INCREASE SYSTEM FLEXIBILITY OF ONE OR
MORE SYNAPSE FRAMES
Although not required to use Synapse Cortex, you are strongly
advised to use a remote personal computer or laptop PC with the
Synapse Cortex software 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 to NOT to touch component 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.
Locating the card The Synapse card can be placed vertically in an SFR18 frame or
horizontally in an SFR04 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
properly may show valid indicators, but does not function
correctl
y
.
REMARK: On power up all LEDs will light for a few seconds,
this is the time it takes to initialise the card.

3 A Quick Start
When Powering-up On powering up the Synapse frame, the card set will receive basic
data and default initialisation settings. All LEDs will light during
this process. After initialisation, several LEDs will remain lit – the
exact number and configuration is dependant upon the number of
inputs connected and the status of the inputs.
Default settings In its default condition, the CDV29 will act as a Reference
distribution amplifier.
Changing
parameters and
settings
The front panel controls or the Synapse Cortex Software can be
used to change settings. An overview of the settings can be found
in chapter 5, 6 and 7 of this manual.

Synapse Cortex
Software
Synapse Cortex Software 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. The Cortex software 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.
A description of how Cortex works can be found in the Cortex
manual, which is downloada
b
le via our website.

4 The CDV29 Card
Introduction The EVS CDV29 is an analog reference distribution amplifier
providin
g
a low loss electronicall
y
balanced input.
Back planes The CDV29 can be used with a BPL01 back plane. If the BPL01 is
used then the CDV29 have nine outputs.
Miscellaneous The CDV29 cards fit into the EVS SFR18 or SFR04 rack.
LEDs at the front of the board indicate the presence of power and
input signal.
The CDV29 can be controlled by EVS Synapse Cortex software.
Refer to menu structure for control.

INSTALLATION AND CONFIGURATION MANUAL

5 Settings Menu
Introduction The settings menu displays the current state of each setting within
the CDV29 and enables the item to be changed or adjusted.
Settings can be changed using the front panel of the Synapse
frame (SFR18 or SFR04) or Synapse Cortex software.
Please refer to chapter 3 for information on the Synapse front
panel control and S
y
napse Cortex software
Input_sel This setting allows the user to determine which reference input is
distributed to the outputs. Choices are Ref1 or Ref2. Input 1 is
the uppermost input of the RRC18 rack controller connection
panel at the rear of the SFR18; 2 is the bottom input. The SFR04
has only one reference input, so the input selection has no
influence on the outputs of the card when using an SFR04.
The option Auto makes the input selection automatically with
Ref1 as priority (so when there is a reference on both inputs, Ref1
will be selected). Whenever Ref1 is lost, Ref2 is automatically
selected.
When the input which you selected with Input_sel is lost, the
CDV29 will automaticall
y
use the othe
r
input.
Switch-Back Switch-Back can be set On or Off.
When Switch-Back is set to On and Input_sel is set
auto, and a change over to channel 2 has occurred (so input 1
was lost), the card will immediately switch back to Ref1 when
Ref1 is OK again.
When Switch-Back is set to Off and a change over to Ref2
has occurred, the input_sell will stay on Ref2 no matter if Ref1 is
back up again, so in this state the card will always stay on Ref2
when a switch-over has occurred (unless Ref2 is lost).
The default setting is Off.
InputGain With GainCtrl set to manual InputGain allows the signal
present at the input to be amplified or attenuated within the range
–6dB to 6dB. The default setting is 0dB.

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? 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 b
y
which the messa
g
e can be filtere
d
CDV29 Events The events reported by the CDV29 are as follows;
Announcements ‘Announcements’ is not an event. This item is only used for
switching the announcement of status changes on/off. 0=off,
other =o
n
Analog_Inp1 Analog_Inp1 can be selected between 0 .. 255. 0= no event,

settin
g
.
Analog_Inp2 Analog_Inp2 can be selected between 0 .. 255. 0= no event,
1..255 is the priorit
y
settin
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 be used in controlling software like Synapse Set-up to show
the event.

EVS Broadcast E

p

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).
Defining Tags The tags defined are:
Event Menu Item Ta
g
Descriptio
n
Announcements 0 or NA 0 or NA Announcing of report
and control values
Input 01hex=INP_LOSS 81hex=INP_RETURN primary input lost or
returned
The Priority The priority is a user-defined value. The higher the priority of the
alarm, the higher this value. Setting the priority to Zero disables
the announcement of this alarm. Alarms with priorities equal or
higher than the Error Threshold setting of the RRC will cause the
error LED on the S
y
napse rack front panel to li
g
ht.
The Address Together with the message string or the tag, the slot number or
address of the card is relevant to be able to assign the event to a
certain card.
