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, 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 of
connection to a computer using Ethernet is described in the
RRC/RRS manual.
!
CHECK-OUT: “AXON 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 Axon Cortex installed, as this increases the ease of use and
understanding of the modules.

Unpacking 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.
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
properly may show valid indicators, but does not function correctly.
NOTE: On power up all LED’s will light for a few seconds, this is
the time it takes to initialise the card.

8
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 Axon Cortex can be used to change
settings. An overview of the settings can be found in chapter 5, 6
and 7 of this manual.

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

Settings Menu
Introduction
The settings menu displays the current state of each GDR216
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.
Note: All items preceded with a #-sign are part of the presets.
SYSTEM SETTINGS
Mode
In the setting Mode you can select how you want to use the
GDR216: 1 input distributed to 16 outputs, or 2 inputs distributed to
8 outputs per input. Set to 1-channel, 1 input will be set to all 16
outputs. Set to 2-channel, 2 inputs will be set to 8 outputs each.
You can also set the card Default is 2-channel.
Input_sel
With Input_sel you can manually or by GPI select how the
GDR216 should function.
In Normal, the card works in default: in 1-channel mode, input
A is set to all outputs. In 2-channel mode input A is set to
outputs A1 till 3, and input B is set to outputs B1 till B3.
In Crossed, the card works inverted. So in 1-channel mode
input B is set to all outputs. In 2-channel mode, input A is set to
outputs B1 till B3 and input B is set to outputs A1 till A3.
When set to GPI1 Latch you can select the way the GDR216
work with GPI1. When GPI1 is open, the card is set to normal.
When GPI1 is closed, the card is set to crossed.
When set to GPI 1/2 mom the way the GDR216 works is set via
pulses on GPI 1 and 2. A pulse on GPI 1 will set to card to
normal. A pulse on GPI 2 will set the card to crossed. GPI 1
and GPI 2 are triggered on the falling edge.
When set to Backup Switch, the card will switch inputs when
the input is lost. When the card is in 2 channel mode, the card
will cross the inputs when input 1 is lost. The setting Switch-
back further down the menu decides whether the card should
switch back when the signal returns.
In its default, the card is set to normal.

14
PLL_set_A
The GDR216 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

■Auto: Auto selection between Bypass and Reclocked.
■Bypass: Does not re-clock the incoming signal
■On: The GDR216 always attempts to re-clock the input
The default setting is Auto.
Mute_A
Mute_A enables input A of the GDR216 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.
PLL_set_B
The GDR216 is capable of re-clocking a range of 3Gbit/s, HD and
SD SDI transport stream bitrates. PLL_Set_B is used to set input
B of the GDR216 to the correct bitrate of the incoming signal.
PLL_Set_B can be set to Auto, 270 Mb/s, 1485 Mb/s and
2970 Mb/s. The default setting is Auto.
Reclocker_B
The setting item Reclock_B determines if the incoming signal on
input B will be reclocked by the GDR216. The settings are:
■Auto: Auto selection between Bypass and Reclocked.
■Bypass: Does not re-clock the incoming signal
■On: The GDR216 always attempts to re-clock the input
The default setting is Auto.
Mute_B
Mute_B enables input B of the GDR216 to be muted. The settings
of Mute_B are On, Off, Input Loss or PLL Unlock. Set to
Input Loss will mute input B only in case a carrier loss is
detected on input B. Set to PLL unlock will mute input B in case
the PLL rate of input B is not available. The Default setting is Off.

15

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 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.
