Hmm.  Maybe it was a peculiarity of the particular patch I was using.  I'll investigate further.

I never noticed such a signal in our system. It might have two reasons:

- The A-100 power supply is not sufficient (the Velleman takes 300mA)
- the microcontroller in the Velleman interferes with the A-100 modules

A separate power supply for the Velleman may solve the problem. A simple
non-stabilized 9...12V power supply is sufficient.
