Pylontech LV Hub Communication protocol

What cable do you use between the Pylontech LV hub and Cerbo GX. I am getting no comms using either of the Victron BMS Can cables (type A or B)

If your hub is showing all the correct ready lights, and it is in the correct port on the GX, maybe try change the bit/ baud rate in the GX device. Should be set to 500kb/s

@marc-1 Are all the pylontech batteries either b or c? The newest models should be at the top of the stack wired as the master.

Thanks Alex and this is what it is. With the Can Bus type B cable connected, the number of lights on the hub indicates 2 stacks (there are 3) and with it unplugged it indicates all 3 stacks. Very confusing
