After a few months off due to work, I now have some free time to work on my modules.
Started to build the wire harnesses for the electrical and came across a small problem. The
zbend manual states that the emergency stop circuit detection is covered in the appendix
and I cannot find it online. Was this ever published? is it necessary?.... I am using the
sugesstion of Rob allbritton for the additional lines. The only one not used is the loopback
pins 20 and 21. Are these even necessary?
