I went and purchased a 100 pack of D-Sub pins ($6,) and have assembled some test wiring. The D-Sub pins are needed, as the jumper wires are meant for breadboards, and the pins on them are a little too small to be gripped by the connector’s receptacles for a good, solid connection. I have now soldered a bunch of them to the ends of the jumper wires. They will eventually be tightly packed together on the connector too, so a bit of heat-shrink will go a long way under those conditions.
So, we are ready to go with proof of concept. Stay tuned.
