Sorama L642 - Release Notes


New event trigger logic: added logic to configure when event triggers are send.

Three new trigger types:

Rising edge detection

Falling edge detection

Dual edge detection

Additionally a timeout can be applied to any event.

New MultiSource data filter: added logic to configure the number of sources the user wishes to visualize on the soundsurface.

Is applicable for a types of soundsurfaces

The user can indicate how many sources they want to visualize on the soundsurface

The SNR threshold can also be set

FF Group integration: allows our LVD data to be integrated into the FF Data Factory from FF Group



Many stability improvements for LVD

Rate limited LVD detection to one LVD trigger at a time

NTP is now checked by the L642 and status is visualized in the dashboard
