Yep, I had about 15 boards (one a 6 input) and an LCD at the peak,
but its dropped off a bit now. I'm now running my own controller,
not the AppCon software, which gives much snappier response than the
old Windows based software.
There is a lesson here; AppCon uses a three byte poll, three byte
message system, and as such theoretically you can get 60 polls per
second on a 2400 baud link, which gives great response, and the
ability to spot dead devices by lack of response.
It is a pity Mr Scargill and Quantech appear to be not as one, for he
built solid kit.
I (still) like the AppCon simplicity. I've started looking at the
ICS interface boxes (eg http://www.bb-europe.com/product.asp?dept%
5Fid=116&sku=I%2D7060) which looks like it'll be just as good, and at
about the same price point if you can use all the I/O per module.
