The above network using CAN bus, the rate of 125 k, B and C for the same equipment, as the main control device, A
Scheme is ABC are now set up 120 ohm resistor, please, see if design right?
If you don't need how to modify the right, is the change of network topology or terminal resistance value?

CodePudding user response:

Or network topology is changed to

Only in the AC terminal resistance, but the BC for the same equipment, plus a without design more difficult

CodePudding user response:

Is the second best

CodePudding user response:

In the second, external terminal resistance, or use the code switch,

CodePudding user response:

CAN no host on hardware connection, from the points of machine, so the first topology entirely appropriate, B and C will be considered A terminal, A pick up in the middle, need only in B, C and terminal resistance

CodePudding user response:

Terminal resistance generally meet the end of the test line, in case of signal transmission form a standing wave
