There were other options discussed at the time. We started with different CAN standards (DB9 comes to mind, so does a 2-row square pin header). But we ended up with the 6P4C modular connector. The form factor seemed convenient, the tools could be found cheaply, the parts were available from many places, etc.

I much prefer the current solution provided by the PDP, PCM, roboRIO, etc. The connection is more reliable, no tools needed (finger), and the foot print could fit inside that of a single 6P4C connector (2x2). Mike and Omar have done a great job.
