From the distance a diagnosis is difficult. Maybe the CEM3340 of the module
is faulty. Please return the module to the dealer where you purchased the
module for repair. I have problems to understand why the A-170 does not work
with with your high end VCOs. The A-170 does not "know" if it is connected
to an A-110 or A-111-1 or any other module. How do you patch the A-170.
And finally: which power supply is used It has to be exactly +12.0 V
and -12.0 V and I do not recommend switched power supplies. But with the
A-100 PUS2 everything should work without problems.
