Thanks for the replies.
Here is all the EVVA EMZY documentation I could find:
User manual (contains most of the info):
https://www.evva.com/fileadmin/user_uplo...l_1-04.pdf
Datasheet:
http://www.evva.se/fileadmin/files_all/D...35i_EN.pdf
Mounting manual:
https://www.evva.com/fileadmin/user_uplo...139.02.pdf
Sadly none of those contain any examples of the open collector connection. Only the specification (12V 300mA).
I came up with a simplified wiring which I think might work. However it all depends on whether my understanding of how the open collector works in general is correct or not...
Basically I am pulling the +12V from the EVVA PSU rather than the +5V from LogicMachine. It increases the draw current but it should still be negligible I think... (1.2 mA)
EDIT: Also I don't know how to find which LogicMachine version I have. It is about a year old, revision 5, Reactor model, CPU (from system info): ARMv7 Processor rev 5 (v7l). It looks more or less like the LogicMachine5 Reactor IO v2 on the OpenRB web page, but without the BNC connector on top.
