Hi Giovanni,

As announced I send you the RTA software as I received it from Lorenzo,
and the settings I stored in the two devices yesterday.
To connect to the controllers, you need the Moxa NPort Windows Driver
Manager.

I used a Moxa NPort 5150 serial device server as Ethernet-to-RS485
converter. It is already configured, you just have to install the driver
and set your computer to an IP address in the 192.168.0.XXX subnet. Then
you have to run the NPort windows driver manager and add a new com port
(Nport IP is 192.168.0.101).
The program will search for the device, it's quite simple to use.
Just ask me if you have questions.

Greetings,
Julian
