Hi Richard,
Of course, I meant the EL6692 - too many sixes and nines... Odd, that looks almost exactly like what I used - the secondary side is basically the same with mirrored In-/Outputs, right? You don't have the odd effects with the operating states as well? Greetings Amos ________________________________ Von: Richard Hacker <h...@igh.de> Gesendet: Mittwoch, 13.

I successfully used that slave in the past, attached is a matlab script for the generic slave in etherlab_lib, but I am sure you would be able to process it for your needs.
