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 AXON Digital
Design Website at www.axon.tv 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 and RRC04 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) manual. The method of connection to a
computer using Ethernet is described in the RRC manual.
! CHECK-OUT: “SYNAPSE SET-UP” SOFTWARE
WILL INCREASE SYSTEM FLEXIBILITY OF ONE OR
MORE SYNAPSE FRAMES
Although not required to Setup a Synapse frame, you are strongly
advised to use a remote personal computer or laptop PC with the
Synapse Setup software as this increases the ease of use and
understanding of the modules.

2Unpacking and Placement
Unpacking The Axon 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.
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
correctly.
REMARK: On power up all LEDs will light for a few seconds, this
is the time it takes to initialise the card.

5
3A Quick Start
When Powering-up On powering up the Synapse frame, the card set will use 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 SAV38 will act as an triple SDI to
triple composite encoder.
Changing settings
and parameters The front panel controls or the Synapse Set-Up Software can be
used to change settings. An overview of the settings can be found
in chapter 5, 6 and 7 of this manual.
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

Synapse Setup
Software
Synapse Setup 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 Synapse Setup 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.
Having selected the desired Frame and Module from the GUI
Synapse Network View, select the menu item that you wish to
open. Opening the menu item gives a complete list of available
properties with their associated Value.
For example to change a setting e.g. SDI-Format, select SDI-
Format form the list of settings by ‘double clicking’ to open a
dialogue box. The dialogue box allows parameters to be changed
or set to default value. On completion close the dialogue box.

7Events 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 message.
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 message can be filtered.
SAV38 Events The events reported by the SAV38 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 =on
Input 1 Input can be selected between 0 .. 255. 0= no event, 1..255 is the
priority setting.
Input 2 Input can be selected between 0 .. 255. 0= no event, 1..255 is the
priority setting.
Input 3 Input can be selected between 0 .. 255. 0= no event, 1..255 is the
priority setting.
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.

14
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.
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 for the SAV38 are:
Event Menu Item Tag Description
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 Synapse rack front panel to light.
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.

15
8LED Indication
Error LED The error LED indicates an error if the internal logic of the
SAV38 card is not configured correctly or has a hardware failure.
Input LED 1 This LED indicated the presence of a valid SDI video signal on
the input.
Input LED 2 This LED indicated the presence of a valid SDI video signal on
the input.
Input LED 3 This LED indicated the presence of a valid SDI video signal on
the input.
Data Error LED This LED indicates one type of error:
-EDH error
Connection LED This LED illuminates after the card has initialised. The LED
lights for 0.5 seconds every time a connection is made to the card.
