Uhm... Not sure if I misunderstand you here, but the devices on the bus SHOULDN'T terminate the bus. There should only be two terminations on the bus, one in each end, and the devices themselves should be high impedance loads. Pretty much like old time coax Ethernet (but 50 Ohm termination).It's designed to be 120-Ohm at the nominal baud rate, but adherence to that impedance specification pretty much goes out the window at the connection points since 120-Ohm connections aren't ever used by equipment that employs CAN-Bus.
See the Brusa to Elithion wiring diagram.I need to wire my Brusa charger CAN bus to my Lithiumate controller CAN bus.
Please see the controller installation instructions. It tells you what type of wire to use, and specifically about the CAN bus wiring.What type of wire/cable should I use? Twisted or not twisted? Will 0.5mm2 be sufficient? Can I use regular UTP Cat.5 data cable?
That is not stranded wire. The instructions specifically say stranded wire.Can I use regular UTP Cat.5 data cable?
Oh? Why not? As long as there are exactly 2 terminations, and they are at the end of the bus, who cares if the termination is physically inside the device or hanging loose on the wires? The CAN termination in the Lithiumate BMS can be turned on or off. The Brusa has no termination.Uhm... Not sure if I misunderstand you here, but the devices on the bus SHOULDN'T terminate the bus.
Yep, but the terminators should always be at the ends. Astronomers post gave me the feeling he that he meant that ALL devices should be 120 Ohm, which would bring complete havoc to the bus.Oh?
