The user manuals contain the pin outs in terms of DIN socket pins 4/5.


If you're that short on space, don't waste 4HP on the breakout, just DIY a cable and run it out the back.


There's also the 2HP sized breakout: https://expert-sleepers.co.uk/tinymidibreakout.html

Then that plus a disting mk4 is 6HP.
