Re: Terminating Resistor CAN

According to my experience the CANBus will have 120Ω across CANH and CANL at each of the ends.
This gives a measured 60Ω between CANH and CANL.
When the CAN transceiver in a CAN node drives dominant the transceiver provides high and low voltage across the termination resistors.
For bench top use, if your bus is short you can probably get away with just one side terminated.
