Hello, I am trying to reading data from device connected via serial communication.  
According to the device manual it transmits 32 signed integers as 64 bytes. I am receiving it in NR, but I don't know how to decode it. I attach screenshot from NR debug node.

Thank you in advance!

However, I suspect you really want sensible properties not just an array of values.

You do that by simply setting names and data types....

does your manual tell you which byte is which and what data size/type they are?

Thank you so much for your help. I attached info from the manual, but I am steel confused how to set the properties of the nodes.  
(the device is gradiometer radar)
