What Does this thing do? Jumper Connector on R-J3ib Controller

  • I think I have a pair of M-16s with that same connector on the back of their controllers. I believe it is a jumper plug for all of your safety signals on TBOP4, up on the door. I'll take a closer look tomorrow, but I'm pretty sure this is what I found.

  • droth is right. It was standard on the R-J2 Control Reliable controllers and part of the GM spec. That carried on to some of the newer controllers GM received to replaced worn R-J2s. Always had one of these jumpers in case someone was using the interface and you needed to troubleshoot. The plug did not jumper the fence circuit so you could jog and run the robot in teach, but not in Auto. Fence was 17-18 & 19-20.


    If you want to build one, this is from my old notes:
