As I was trying to make the RJ12/DB9 convertor, I was putting the pins in the slots and testing to see if it worked, and on one attempt, all of my brown jaguars stopped flashing. I checked to see if they were still getting power with a multimeter, and they were. The black jaguar is still working, and the PD board is fine. I don’t think they all got fried, because it would be too random for seven motor controllers to get fried at the same time. I am using a CAN bus system and when I put a new jaguar at the end, it worked.
