Thanks Gambit. I think I almost had that figured out. I have used the A CPU's for 20 years & just starting to use the Q series on a few projects. So I am getting the impression that it will be easier (once I get it working once), but I am still getting started.
What are these "pre-defined" protocols - you can point me in the right direction or towards a manual & that should be all I need.
Thanks again
