Establish a connection to siwarex ms by using siwatool ms.

Hello, I am boiling my brain for a few Days, trying to connect to siwarex ms, using siwatool ms.

I have tried to use various USB to rs232, I made a cable as per instructions 2-3..3-2...5-5.

I am using Digitus ftdi adapter...I still have no success... numerous retries and communication error.

I have changed everything in the configuration, laptop, windows, USB adapter, cable...even a few siwarex ms modules.

Does anyone know the trick with this ?
