I have a customer that has an Andover NetController running a network of around 100 field controllers, a mix of VAVs and Fan Coils, using Infinet. Their front end has finally crashed and they are looking for us to install something else. I have done some research and it looks as if we can install a JACE with the Infinet driver. My question is, does the existing NetController have to stay or is it better to replace it with the JACE? I was thinking that it needs to stay and we would interface to it through one of the existing NetController Com ports, but I have never done this and am unsure. Will we be able to connect automatically or does the NetController have to be setup for RS485 communication? Thanks.
