Hi Team,

I am trying to connect to a RMA42 process transmitter using a Commubox FXA195 USB/HART modem.

I am using DeviceCare 1.08 and it looks like the DTM is installed.

I have used HART on many other devices but for this one I am having no joy.

Has anyone successfully connected to the RMA42 using HART?

The commubox has a build in resistor for HART, I also tried every configuration I can think of.
