When using PRS-4OMI4 in a Praesideo system, there was a delay and jittering when they made an announcement from 1 NCO to the other NCO
The problem was caused by older OMNEO firmware within the OMI’s.
Though the Praesideo software in the OMI’s was relatively up-to-date (4.37), the OMNEO firmware was not. Unfortunately, updating the Praesideo software through the optical bus does not also update the OMNEO firmware as this is a completely different path (OMNEO is updated through the Ethernet connection of the OMI).
Due to some issues with OMNEO Firmware Update Tool v5.40 not working with unsigned firmware files (and the OMNEO firmware files are unsigned), it’s recommended to use OMNEO FWUT that comes with the Praesideo software folder. This version can be found on the Praesideo software folder then the folder 'Tools' , 'PRS-4OMI4 config tools'.
