Signal two bus
Thread Content
May I ask everyone, what is Signal 2 bus like? How many wires are there, and how is it connected to the instruments? What if the instruments are spread out over a large area?
A two-wire bus is nothing but a 2-wire communication line with voltage applied to it; it can be connected in any way, as there are only two wires after all. Just like hanging grapes, attach each speedometer one by one.
Is it two-wire, or a field bus?
