it is just a little complicated, plenty of info on setup though.
I would get through it, once you are done you will have minor problems setting it up in the future.
I had problems with about 4 settings, after I got that resolved everything went great.
It is a lot easier if you only want to read (not write to device)....you don't have to close the connection, just set a timer for how often you want to read required integers.
This is important if you have more than 1 device you want to read from, just sequence the read commands so you do not try to read from more than one device at the same time.
