The change in gauge is a sighn that there is a problem using APP for CAN bus, and the actual reason is one of signal reflection. Remember that CAN is essentially a serial data transfer protocol. Any "fat" or "thin" spots in the cable will tend to reflect the signals, resulting in noise in the communications. You will probably get away with it up to a point, but at some threshold it suddenly become a showstopper. While I do not have any experience with this, I am looking strongly at the 2-pin version of the relatively new "ditto" genderless connector from Molex with the 20-22 AWG crimp connector to fill this need as we move to Talon SRX and CAN bus. |
You will first have trouble getting the 22AWG crimped in the PowerPole contacts properly.
You may have to purchase a tool to crimp those Molex connectors. If you already have the tool for crimping the contacts for making PWM cables, just use the latching connectors from Hansen Hobbies since they work with the same tool.
