I have a job that I'm changing the NCM out for an NAE. Its an NAE45 with 27 UNT controllers and 3 DX's. The owner wants a warm fuzzy before he switches over to the NAE. When we are there during the day we plug in the NAE and at night plug in the NCM. When trying to adj Setpoints and or override Stpts, the response time go from almost instantanious to +-5 minutes. I've run scan software on the N2 bus and all of the controllers return with a response time of approx. 35ms. The NAE is running Ver. 2.1. Is there any possible conflict that can occur in the controllers due to this change every night or do older controller revs (around 8 Years old) have anything to do with it.
