Indeed there is a inconsistency in the CV handling of the A-110 and the A-111-1. But as far as I know it's described correctly in
the user manuals of the modules. The A-110 uses a normalled socket with switching contact to interrupt the bus CV as soon as a plug
is inserted into the CV socket at the front panel. For the A-111-1 (and all other later modules that have access to the bus CV, e.g.
A-111-5, A-111-2) the CV's of the bus and the front panel socket are added. We found that this is more flexible than the normalling
version. And there is another reason: over the years (the A-100 is nearly 20 years on the market) the switching contacts may wear
out because of inevitable material fatigue or corrosion or unwanted dust between the metal parts of the socket. That why we try not
to use normalled sockets if it's avoidable.
