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 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 The remote control options are explained in the rack controller
Capabilities (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.

2 Unpacking and Placement

Unpacking

The EVS 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.

NOTE: On power up all LED’s will light for a few seconds, this is the time it takes to initialise the card.

INSTALLATION AND CONFIGURATION MANUAL AAD08

3 A Quick Start

Power-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 dependant upon the number of inputs connected and the status of the inputs.

Default settings In the default condition, the AAD08 will act as a dual channel 1 to
8 Analogue Audio Distribution Amplifier.

Changing settings The front panel controls or the Synapse Set-Up Software can be
and parameters used to change settings. An overview of the settings can be found
in chapter 5, 6 and 7 of this manual.

Synapse Setup Synapse Setup Software can be used to change the settings of

Software

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 SDIFormat 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.

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 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.

AAD08 Events The events reported by the AAD08 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_CH1 Input_CH1 reports the loss of the audio at the input of channel
1 by detecting Silence and can be set between 0 .. 255. 0= no event, 1..255 is the priority setting.

Input_CH2 Input_CH2 reports the loss of the audio at the input of channel
2 by detecting Silence and can be set between 0 .. 255. 0= no event, 1..255 is the priority setting.

Audio-Data_CH1 Audio-Data_CH1 reports if channel 1 audio has reached the
Peak level set by the setting item Peak-CH_1 and can be set between 0 .. 255. 0= no event, 1..255 is the priority setting.

Audio-Data_CH2 Audio-Data_CH2 reports if channel 2 audio has reached the
Peak level set by the setting item Peak-CH_2 and can be set between 0 .. 255. 0= no event, 1..255 is the priority setting.

What information is The message consists of the following items; available in an
13

INSTALLATION AND CONFIGURATION MANUAL AAD08
event? 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.

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 AAD08 are:

Event Menu Item Announcements
Input_CH1
Input_CH2
Audio-Data_CH1 Audio-Data_CH2

Tag 0 or NA

0 or NA

01hex=INP_LOSS

81hex=INP_RETURN

Description Announcing of report and control values Ch 1 input lost or returned Ch 2 input lost or returned Audio data error Audio data error

14

EVS Broadcast Equipment SA

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.
