Send SEV Rename Packets

 sends a UDP packet containing the tank and block name over the

local network to the RS4, so that the RS4 can rename the data 

fi

les correctly.

When 

Phantom Store

 is selected, 

Send SEV Rename Packets

 is selected for you.

Use Large Buffer Size

 allocates more DSP memory to buffer the data before it is transferred to

the RS4. This improves reliable when streaming very high bandwidth, high channel count data
to   multiple   RS4   ports.   The   RS4   should   be   updated   to   v1.19  

fi

rmware   or   above   to   most

effectively use this setting.

Recording Sessions

When Synapse enters Preview or Record mode, the RZ begins streaming data to the RS4. This
initiates  a recording  period or session on the RS4. A session is de

fi

ned  as any length of

continuous streaming data sent to an RS4 streaming port. Each streaming port on the RS4 can
initiate a session and sessions may run concurrently.

If the RS4 sees data coming into a port, it opens new 

fi

les and starts saving the raw data to

disk. The RS4 otherwise doesn't know anything about Synapse state (Idle, Preview, Record).
Synapse sends the RS4 information over the network via small UDP packets every 5 seconds.
Each   packet   contains   the   tank   and   block   name,   so   that   the   RS4   can   rename   the  

fi

les

appropriately. Make sure the 

Send SEV Rename Packets

 option is enabled in Synapse.

When data is no longer streaming to the port for a period of time longer than the 

Rec Stop

Timeout

 setting, the session is concluded and a new session will begin when a new data

stream is presented. This is set on the 

Con

fi

g Tab

. The default is 10 seconds but you may want

to shorten that to 3 seconds.

For long recording sessions, the RS4 touchscreen con

fi

guration settings include an option to

Segment 

fi

les every

 with several time options to periodically close and reopen the session.

This partitions the recording into multiple smaller data 

fi

les that may be easier to analyze if you

are doing long multi-day recordings. See 

Ports Tab

 for more information.

If you aren't using TDT applications to read the data saved on the RS4, you don't need to select 

Phantom Store

 but

you 

absolutely

 should select 

Send SEV Rename Packets

 so that the RS4 data is organized properly.
