<p>Hi Richard,</p>
<p><br>
</p>
<p>Of course, I meant the EL6692 - too many sixes and nines...</p>
<p><br>
</p>
<p>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?</p>

<br>
You mean the EL6692 ;)<br>
<br>
That must be some mistake somewhere on your side. I successfully used <br>
that slave in the past, attached is a matlab script for the generic <br>
slave in etherlab_lib, but I am sure you would be able to process it for <br>
your needs.<br>
