I know you need to terminate the 'ends' on a high speed CAN bus but what if you know nothing about the topology of the network or where the bus will go. For my application i have designed a data acquisition unit for a vechile and want the ability to add nodes to the network as i please. The location of the devices that may be used is unknown so in that sense im finding it difficult to define what the ends of the bus are.

Can i terminate the bus on the same circuit and have connections to the bus through that device

                    [node1]      [node2]

I know you need to terminate the 'ends' on a high speed CAN bus but in large networks does it make any difference which nodes you choose as the end of the bus?
