I have a building with old JC C210 vav controllers monitored by an NCM 200, and would like to replace them with VMA14xx and an FX40. I understand that there are a number of issues with VMA controllers and the FX40. Any insight would be great. I have several other N2 controllers in the building already.

There are some quirks with VMA's and the original N2 driver, nothing earth shattering but a few mysterious things. The Updated driver when 3.2 eventually comes out for FX-40's are said to be improved.

You know you are not locked into VMA's , right? The FX has a Lon trunk as well, and You could pick any flavor of Lon controllers for your retrofit of the old boxes.
