Need Help! Moxa NPort and Burny 2.5 Plus

Hi!
I am a newbie, and hope someone can give me some advice....
I intend to replace an old manual serial switch who connects two Burny controlled CNC cutting maschines to a computer. I was looking at the moxa Nport 5200A 2 port RS-232.
Is it possible to use this in combination with the Burny 2.5 controller?
Could anyone recommend a communication program for transfering data between pc and CNC?
I have downloaded a copy of DNC Presicion. Anyone who have tried this?


Thanks ahead
Bjorn
