Hello, I have an issue. I bought a can bus simulator, specifically of J1939 protocol. I tried it with a FMB640 and the device can read the simulated data perfectly. Now I want to read the same data with a FMB120 using an All Can. The problem is that when I connect the all can to the simulator, the led doesnt start blinking, and I dont know how to get a program number that works. Should I be able to read the simulated data with the All can? Is it possible the All-Can doesnt recongnize the simulator?
