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, RRS18, RRC10, RRC04 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/RRS18/RRC10/RRC04/RRS04) manual. The method of
connection to a computer using Ethernet is described in the RRC
manual.
! CHECK-OUT: “SYNAPSE SETUP” SOFTWARE WILL
INCREASE SYSTEM FLEXIBILITY OF ONE OR
MORE SYNAPSE FRAMES
Although not required to set up 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.

4
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.

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 PBS03 Card
Introduction The AXON PBS03 is a dual channel digital serial component
(DSC 270 Mbit) video switcher. With integrity checking. The
PBS03 has 2 SDI inputs to 2 outputs. The loop-through input is
high impedance and must be terminated in 75 Ohms when not
used.
EDH Status The PBS03 monitors the EDH status of the incoming SDI stream
in order to assess signal quality.
TRS Status The PBS03 makes a changeover decision based on the number of
the TRS found in the incoming SDI stream. There are two
occurrences of the TRS symbol per digital video line, one at the
start of active video and the second at the end of active video.
Freeze Status The PBS03 is able to changeover based on the number of frozen
frames detected in the incoming SDI stream.
Embedded audio
status The PBS03 is able to changeover if the embedded audio is no
longer present or if it contains silence.
Switch back logic The PBS03 has the capability to check the “ switch to “ channel or
to automatically do the switch.
General Purpose
Input A GPI input is provided to provide an external means of changing
over to the second input.
8 Relay Outputs Eight relay outputs are provided to allow the switching of up to
four channels of balanced audio.
Relay for active and
backup channel The active and backup channels are relay switched.
Back planes The PBS03 can only be used with the BPX02 back plane.

9
Miscellaneous The PBS03 cards fit into the Axon SFR04 & SFR18 rack.
LEDs at the front of the board indicate the status of the SDI inputs,
Active Channel, Manual Overwrite and Connection.
The PBS03 can be controlled by Axon Synapse set-up software.
General Note that it is necessary to terminate this output if the Channel
Boutput is not used. Otherwise the card will not function.
We see Input_A as the Main channel and Input_B as the back
channel.
On output A the channel that is active at that moment is always
displayed. On output B the channel that is not active at that
moment is displayed.
It is possible to set criteria for integrity checking (carrier, TRS,
freeze, audio silence) for both the Main and Backup
channel. There is logic if the card switches to the backup even
when the other channel contains errors or it will switch only when
the other channel is ok. It is possible that the card will switch back
automatically or it will stay on the backup channel even when the
main channel is ok again.
It is possible to switch between Main and Backup using an GOI
contact.
A Synapse card can generate an event in case of loss of input etc.
The PBS03 is capable to monitor events and will switch from main
to backup. It is necessary that the PBS03 is in the same frame as
the other card that should be monitored.

5Settings Menu
Introduction The settings menu displays the current state of each setting within
the PBS03 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.
Note: When the PBS03 is in auto mode and switched to channel 2
(if switch back = off) then it’s possible to switch to channel 1 with
GPI contact number 3. See appendix for pin out.
Mode Mode determines how the card will switch between the two
channels.
AUTO the card will switch from the main channel to the backup
channel according to the criteria set (Carrier, TRS, Audio
silence,Freeze, Event)
MANUAL: it is possible to switch between the main and backup
channel manually (the actual switch determined by the setting
Manual-Sw).
GPI-Sw: the PBS03 has local GPI inputs. With this contact it is
possible to switch between the main and backup channel.
The default setting is AUTO.
Note: When the PBS03 is in auto mode and switched to channel 2
(if Switch-back is set to ‘off’) then it’s possible to switch to
channel 1 with GPI contact number 3. See appendix for pin out.
Manual-Sw If the option Manual is selected in Mode, this setting allows you
to switch between the Main and the backup channel.
Options are SDI –In_1 and SDI-In_2
The default setting is SDI-In_1
Sw_GPI_1 SW_GPI_1 determines that in case of a GPI closure (GPI
contact one), the MAIN channel is active (for a switch to channel
two close GPI_2 and set the SW_GPI_2 setting to ON).
In Mode GPI should be selected.
The default setting is OFF
Sw_Carrier_1 Sw_Carrier_1 determines that if an SDI carrier is no longer

11
present in the main channel, the card will switch to the backup
channel.
This only works when the backup channel is Ok (if that is set in
the setting Back-up OK and if Sw_Carrier_2 is set to ON)
The default setting is On
Sw_TRS_1 Sw_TRS_1 determines that when the criteria of the TRS are no
longer are fulfilled, it will switch from Main to Backup.
TRS errors are signals that have less than 450 TRS in 250 Lines.
TRS is a sum that is calculated for each video line.
Please note that this only works when the backup channel is Ok
(if set in the setting Back-up OK and if Sw_TRS_2 set to ON)
The default setting is OFF
Sw_Aud_Sil_1 Sw_Audio_Sil_1 determines that when there is silence in the
embedded audio of the main channel, the card switches to the
backup channel.
Please note that this only works when the backup channel is Ok
(if that is set in the setting Back-up OK and if
Sw_Aud_Sil_2 is set to ON)
The default setting is OFF
Sw_Freeze_1 Sw_Freeze_1 determines that when there are frozen frames in
the main channel, the card switches to the backup channel.
Please note that this only works, if the backup channel is Ok (if
that is set in the setting Back-up OK and if Sw_Freeze_2 is set
to ON)
The default setting is OFF.
Sw_Event_1 Synapse cards can produce events (input lost etc.), if the card is
located in the same frame as the PBS03. In that case the card can
switch from main to backup. With SW-Event_2 the PBS03 is
set to perform this action.
Sw_GPI_2 W_GPI_2 determines that in case of a GPI closure (GPI contact
one), the MAIN channel is active (for a switch to channel two
close GPI_2 and set the SW_GPI_2 setting to ON).
In Mode GPI should be selected.
The default setting is OFF
Sw_Carrier_2 Sw_Carrier_2 determines when there is no longer an SDI
carrier present on the backup channel, the card will automatically

12
switch to the main channel. Please note that this only works when
the setting Switch back is set to ON.
The default setting is On.
Sw_TRS_2 Sw_TRS_2 determines when the criteria of the TRS are no longer
fulfilled; it will immediately switch from Main to Backup. Please
note that this only works when the setting Switch back is set
to ON.
Sw_Aud_Sil_2 Sw_Audio_Sil_2 determines when, in case of silence in the
embedded audio of the main channel, the card is allowed to
switch to the backup channel. Please note that this only works
when the setting Switch back is set to ON.
Sw_Freeze_2 Sw_Freeze_2 determines when, in case of frozen frames in the
main channel, the card is allowed to the backup channel. Please
note that this only works when the setting Switch back is set
to ON
Sw_Event_2 Synapse cards can produce events (input lost etc.), if the card is
located in the same frame as the PBS03. In that case the card can
switch from main to backup. With SW-Event_2 the PBS03 is
set to perform this action.
Auto-Sw Auto-Sw: this setting determines if the card always switches
from the main channel to the backup even when the backup
channel is not ok. The criteria are set in the settings above.
Back-up Ok: In this case the card will check if the backup
channel is ok before doing the switch. That is, if the criteria are
set in the settings above.
The default is Back-up OK.
Switch-Back Switch-Back can be set On or Off. The default setting is On.
When Switch-Back is set to On, and a change over to channel
2 has occurred, the PBS03 will immediately switch back to
channel 1 if the quality of channel 1 improves to a level where
there are more than 510 TRS in 256 lines in Channel 1.
When Switch-Back is set to Off, and a change over to
channel 2 has occurred, the PBS02 will only switch back to
channel 1 if channel 2 has less than 450 TRS in 256 lines an the
condition of Channel 1 is OK.
Default setting is ON
FrontSwitch This setting enables or disables the switch mounted on the front of
the PBS03 card The settings of Front-Switch are Enable &

13
Disable. The default setting is Enable. When enabled, the
front switch overrides all other changeover settings.
Enable: When Front-Switch is set to Enable, the switch
mounted on the front of the PBS03 card allows switching between
channel one and channel two of the PBS03. The manual override
LED blinks to confirm that the PBS03 is in manual mode. If the
switch is held down for 3 seconds, the blinking LED is switched
off.
Disable: When Front-Switch is set to Disable, the
switch mounted on the front of the PBS03 card is disabled and
does not allows switching between channel one and channel two
of the PBS03.
Default setting is ENABLE.
Freeze-frmr FREEZE-Frmnr allows to set the number of frozen frames that
should initiate a changeover. The related range is from 10 to 2047
frames.
Default setting is 70.
Freeze-hold FREEZE-Trsh determines the sensitivity level of the Freeze-
Frmnr. Digital, Analog_Lsens, Analog_Msens, Analog_Hsens
are the options.
Digital when the source has a digital origin
Analog_Lsens when th
e origin source is analog, the sensitivity is LOW.
