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.
A Quick Start When Powering- 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.
Example of With the display as shown below changing parameters using front panel control RRC18 [Select Card] >S01=SFS10 Pressing the ► selects the SFS10 in frame slot 01. The display changes to indicate that the SFS10 has been selected. In this example the Settings menu item is indicated.
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.
The DBD18 card Introduction The DBD18 is a quad speed ADD-ON Dolby E decoder. The card is designed for the use with the Synapse high efficient quad speed multiplexing audio bus. The quad speed bus enables ADD-ON cards to be connected with a master card and have both input and output signals connected to this card for convenient routing and integration.
(next setting). The rates have to be the same. Lock-Mode The DBD18 can be used as an ADD_ON card (in combination with an embedder/de-embedder card). In this case you are referred to the setting MasterCard, which will extract the reference from the master card.
INPUT CONTROL Dolby_E_in Here you select where the Dolby E comes from: from the local AES/EBU inputs, or from the master card via the add-on bus. Default is local. Ch_E_in With this setting you appoint specific channels within the input source set with Dolby_E_in, which should contain Dolby E.
Sel_Ch1 ~ With these settings you set a source for the corresponding output Sel_Ch16 channel. You can set each individual channel to source Local (physical AES/EBU inputs), Master (audio coming from master card via add-on) or Decoded_E (audio coming from the Dolby decoder).
MULTIPLEXING CONTROLLER AUDIO BUS INTERNAL SYNAPSE BUS Override 25/32 With this setting you can choose whether you want to override input channels 25/32 on the add-on bus of the next add-on card (right side) with output channels 9 to 16 or pass the master-card audio.
Status Menu Introduction The status menu indicates the current status of each item listed below. Lock_status This status item indicates whether the card is locked to the, with setting Lock-mode selected, source. Can be (OK) or not locked (NA) AES_Input_1 ~ These items display the status of the 4 AES/EBU inputs.
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.
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...
LED Indication Error LED The error LED indicates an error if the internal logic of the DBD18 card is not configured correctly or has a hardware failure. Input_1 LED This LED indicated the presence of a valid AES/EBU audio signal on input 1.
Connector Panels The DBD18 can be used with the BPL11 or BPX11. The following table displays the pinout of these backpanels in combination with the card. BPL11 BPX11 AES/EBU IN 1/2 AES/EBU IN 3/4 AES/EBU IN 5/6 AES/EBU IN 7/8...
Appendix 1 Quad speed ADD-ON bus The internal audio ADD-ON bus needs an upgrade. We want Scope more channels (32 per video stream seems possible in the near future). And we want the bus to be bidirectional, so 32 channels in and 32 channels out at the same time. The new interface needs to be compatible with all existing hardware (frames) and in the implementation of the master card it needs to be backward compatible with the original ADD-...
loop The quad speed bus can also work in one direction You can use a Quad Speed audio bus to de-embed audio from the master and present on the ADD-ON card as AES/EBU, Bitstream (like Dolby) or analog audio If applicable the ADD-ON card can also be used as in ...

Multiplexing The injection of processed audio into the master card works differently then you were used to with the original audio ADD-ON bus. The brown large arrow will always carry 32 channels from ADD-ON to ADD-ON, or from ADD-ON to Master Card. If the actual channels are used or which channels are used is determined in the ADD-ON card.
