To answer Jim's question first, yes.
To answer Phil's question, it is really about activity. Let say that you had 20 nT60s connected, but only ONE was being used at a time....It would take a long time to "push-out" the graphics, but we know the nTouch 180 can manage one nT60.
Now, PLEASE don’t even think that I’m saying how many nTouch 60s the nTouch 180 can handle, other than 5 to 7.
That said, back when we came back from Thanksgiving break (end of November), I had gathered up twenty nTouch60s in my office. I was going to add them to the nT 180 until it “broke”…Then another project came up that has absorbed all my time for the last four months. Hopefully, I can get back to this project sometime soon, and give you some “real world” numbers.
Make it intuitive, never leave them guessing.
