[Etherlab-users] Experience with EL6992

[Merkel, Amos]

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

Hi Merkel

You mean the EL6692 ;)

That must be some mistake somewhere on your side. 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.
