Olivier,

this is one of the seldom not working patches. The reason is that the A-110
rectangle output is DC coupled but the A-111 rectangle output is AC coupled
with a capacitor at its output. We overlooked this specialty when the A-163
was designed as it has been always tested with the A-110 only. There are two
possible solutions: shortening the capacitor C10 of the A-111 (located on
A-111 board C close to the 10 pin connector). This changes the output from
AC to DC coupling (even a switch can be added). Another solution that should
work is to add a pull down resistor (about 10...100k) to the A-163 input
(from the input to GND). But I have to try this out.

Best wishes
