The point is the Alarm cable will still work even if Aquasuite and/or Windows is locked up, crashed, or not running. What your screen shots show require that Windows, Aquasuite, and the Aquasuite service are all up and running. The Alarm cable connection is therefore more reliable, and since the purpose is to shut down in an emergency situation, reliability is a good thing. Some people use an Octo in a Linux system that can't run Aquasuite. The alarm cable is also useful in this situation.
I understand better, thank you
After checking, I can confirm that if Aquasuite is closed, it works
but if Aquasuite is closed and Windows is locked, it doesn't !
