Doepfer

Hello list,

I just bought an A-185-2 precision adder and an A-164-1 manual gate, but neither one seems to be sending signals to the bus.  I have an A-111 on the same bus as the 185-2 in a Doepfer suitcase, and an A-140 on the same bus in a Base Case, but neither one of them is responding.  The modules are working if I patch them.  I've never tried to use the bus before.  Is there something I need to do to prepare the bus?

thanks,
Ernst
