Hello!
I want to connect two High Speed CAN transceivers (MCP2551) but I don’t know exactly how to do it. Is it enough to link the CANH and CANL pins of the transceivers or do I have to link also the grounds? What connector is the most suitable? Is a DB9 ok? Do I have to terminate the bus with a termination resistor at both ends of the bus in order to avoid reflections? Or are those resistors included in the transceiver? (I read the transceiver’s datasheet and they don’t mention those resistors).
Thanks a lot in advance for your help!
