I need help, I have an ECU CAT engine 3516B. From the drawing the CAN Bus Communication protocol is a J981 and J982. I need to connect it to my OEM deepsea controller with CAN Bus J1939 or Modbus rs485. Can J981 connect with J1939 or it required an interface? To read the CAT ECU engine information with my deepsea 7310 controller. What is the interface required it does so.
