| I was just going to ask about terminators. So they are nothing more than small resistors? What wires are they between?
Am I understanding it correctly if I would say a typical Canbus or Isobus system has 3 wires on the communication side? A high wire and a low wire, who’s voltages combined would be 5 volts, and a ground?
If so, what is the purpose of having both voltages?
And yet another question. I think a lot of the sensors run on 5 volts but as far as I understand you can’t actually just add the two voltages together to get to 5 volts. Would the voltages actually be one wire with 1.7 (not sure of exact voltage) volts difference to ground, one wire with 5 volts difference to ground, and of of course one ground wire? The combined voltages as explained as adding up to 5 volts would actually be the initial 1.7 volts to ground and then an additional 3.3 difference to the 1.7 volt wire?
I hope my questions made sense and sorry for the multiple questions. I just don’t really understand the basic structure of these systems and the reasons for multiple voltages. | |
