Graynomad:
Unfortunately I don't have a transceiver here.
It's a balanced, multi-drop, open drain link, I doubt it will work without transceivers.

You are correct. It won't work without either transceivers or some extra EE magic to make the signals compatible. It's not worth it to try to doctor something up because transceivers are pretty cheap. It's all around best to just get the transceiver chips and use them.
