The output side of the transformer is not center tapped. The input side
is. The input side center tap needs to connect to ground. On the
ADT1-1WT and the ADT4-1T the center taps are on pins 2 and 5
respectively. That's why I connect both -- so that you could switch to
the other transformer if you wanted. You would only want to do that for
the RX side, though.
So in short, there is no short. :)
Ok, that is clear.
How about my calculation of the impedance.
Did you have a change to look at those.
7 Ohm is a bit low when the minimum is 25.
Or did I get my calculation wrong?
Still this wouldn't account for the difference between 50 mV and the expected
1000 mV.
