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/RRS18/RRS04) 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 the default condition, the GPI16 acts as a universal GPI input &
Output card for the Synapse SFR18/SFR04 frame.
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.

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.

4 The GPI16 Card
Introduction The AXON GPI16 card is a universal Synapse GPI I/O
(Input/Output) card. The card is capable of forcing GPI output
triggering based on events that are generated by cards located in the
same rack. (E.g. An alarm/event generated by any specific card in
frame. This alarm/event is put on the bus. The GPI16 card will
monitor the internal bus for events and close a relay in case of an
event.)
The GPI16 can also be used as a slave card for Synapse functions, the
8x1 switcher or the VWI10 card for example. In these applications it
is possible to control functions directly in to a Master, e.g. GPI based
channel selection of the 8x1 switcher SDX08.
Back planes The GPI16 can be used with the BPL06 backplane.
Miscellaneous The GPI16 cards fit into the Axon SFR18 or SFR04 rack.
LEDs on the front of the board indicate the presence of electrical
input signals & Processor Errors.
The GPI16 can be controlled by Axon Synapse Set-Up Software.

9
5 Settings Menu
Introduction The settings menu displays the current state of each setting within the
GPI16 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 Setup software.
Please refer to chapter 3 for information on the Synapse front panel
control and Synapse Setup software.
Source The settings item Source controls the functionality of the card. The
GPI16 can be either used as a general purpose card or a card
dedicated to one master card.
The settings of Source are;
Frame: The GPI16 is set to general purpose where events from
several cards within the Synapse frame can be mapped to the GPI16.
The card can be placed in any slot of the frame.
Mastercard: When the GPI16 is set to Mastercard. The GPI16
then functions as an interface between a mastercard (VWI10, SDX08,
ARC20) and hardware switches or automation pulses. The GPI16
card has to be placed at the right side of a mastercard.
The default setting of Source is Frame.
GPI_in GPI_in can be set to Latch, Non_Latch, or Loop-Through.
Latch when a contact is closed all the time. Non_Latch when a
contact is closed momentarily. Loop-Through When you want the
GPI outputs to be triggered by the GPI inputs.
The default setting of GPI_in is Non_Latch.
DeBounce DeBounce ON will de-bounce the GPI inputs when a mechanical
switch is used. OFF will de-activate this feature. OFF also improves
the reaction speed.
Default is On.
GPO_1-Card When the settings item Source is set to Frame, the setting
GPO_1-Card is active. GPO_1-Card maps GPI output 1 to the
card in the selected slot within the Synapse frame. GPO_1-
C
ard
select slots 1to 18 and can also be given the setting 0. When
GPO_1-Card is set to 0, all slots with the Tag selected will provide
the source for the GPI switching, (see Setting item GPO_1-Tag
below). The default setting of GPO_1-Card is 0.

10
GPO_1-Tag When the settings item Source is set to Frame, the setting GPO_1-
Tag is active. GPO_1-Tag selects the Tag that will be used to
enable the GPI output to switch for the card selected in setting item
GPO_1-Card.
There is no TAG selected, when the value of the GPO_1-Card is 0.
The TAG number can be found in the events menu of the card that
has to be controlled. E.g. loss of input is TAG1. And also the TAG
can be found in the manual of the card that has to be controlled.
Most important TAGS:
Lost input = TAG1
Lost reference = TAG2
EDH status = TAG3
ANC status = TAG4
Audio data = TAG5
GRP-insert = TAG6
The default setting of GPO_1-Tag is 0.
GPO_2-Card to
GPO_16-Card The functionality of GPO_2-Card to GPO_16-Card is the same as
GPO_1-Card. Please refer to the above description for details.
GPO_2-Tag to
GPO_16-Tag The functionality of GPO_2-Tag to GPO_16- Tag is the same as
GPO_1- Tag. Please refer to the above description for details.
GPOut_1-Default ~
GPOut_16-Default The GPI outputs are based on mechanical relays. The advantage of
using a relay is the galvanic isolation and polarity independent
switching capabilities. The relays have switch over contacts with a
normally closed (NC) and normally open (NO) contacts. The default
position is: On. This means that in the default state all relays are
activated and the NO contact is closed. The advantage is that if the
card looses power all relays will be in their non-activated state.
The settings menu items GPOut_1-Default till GPOut_16-
Default allows the relays to be put in their released (non-activated)
state which also can be used as manual triggering of the GPI outputs.
The state can also be changed by the GPInputs 1 till 10.
The settings of GPOut_1-Default are On, Off and
G
PI_1
till GPI_10. The default setting of GPOut_1-Default is On.

11
6Status Menu
Introduction The status menu indicates the current status of each item listed below.
GPIn_1 The status item GPIn_1 indicates that GPI input 1 has been
triggered. If a voltage is supplied to the input the status will be
displayed as On, if a voltage is not present the Status will be Off.
GPIn_2 to GPIn_10 Please refer to the description of GPIn_1
GPOut_1 The status item GPOut_1 indicates that GPI output 1 has been
triggered. This means that activation of this GPI output relay changes
it from the default state selected in GPOut_1-Default.
For example, if GPOut_1-Default is set to Off. In its un-
triggered state the GPOut_1 indicates Off. When the output is
triggered the status changes to On.
GPOut_2 to
GPOut_16 Please refer to the description of GPOut_1

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.
GPI16 Events The events reported by the GPI16 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
GPI_1 GPI_1 generates a GPI trigger and can be selected between 0 .. 255.
0= no event, 1..255 is the priority setting. When a GPI input is
activated, an event will be generated.
GPI_2 to GPI10 Please refer to GPI_1.
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.

13
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.
When an 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 GPI16 are:
Event
Menu Item
Tag* Description
Announcements 0 or NA 0 or NA Announcing of report
and control values
GPI 08hex=GPI_ON_# 88hex= GPI_OFF_# GPI relay event
* For all tags see selected card numbers
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.

14
8LED Indication
Error LED The error LED indicates an error if the internal logic of the GPI16
card is not configured correctly or has a hardware failure.
Input LED The Input LED illuminated to indicate a GPO trigger.
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.
