Trying an official experiment from the Microtronic manual to check compatibility of the output ports with Busch electronics experiments / circuits as described in the Microtronic manual. I had the output ports inverted previously - with that being fixed in the firmware, the experiment conducted here demonstrates principles of "data transmission". The Microtronic Next Generation is driving a CLOCK and a RESET line into a Busch 2075 Counter Module, and a (decimal) digit is being transmitted from the Next Generation to the Counter Module. With the corrected firmware (non-inverted outputs) it works fine.
