Let's see if my DCS NB is the latest firmware

I haven’t used DCS NB for a long time. After opening it today, I updated Mosaic, but found that the MAIN BOARD VERSION is still version 1.02. Do I need to use a computer to update the main firmware? thanks

It looks just fine - my NWB has the same versions.
The latest update is for dCS Mosaic only - for the app and for the part of Mosaic that resides in the network board.
So all should be well with your Network Bridge.

How to update MAIN BOARD VERSION

The dCS Network Bridge is now a legacy product, no longer updated.

The latest updates you can find here: https://dcsaudio.com/documentation

It seems you already have the latest version:

Many thanks Ermos
