Hi new around here, so hello to you all AVRfreaks.
As the topic says, is it possible to connect CAN nodes in a star or split (physically) configuration, instead of the typically chain configuration?
E.g. Say I have a project for one customer and start with a normal chain configuration with several nodes and the terminate resistors at both ends. So far nothing special, but after a few years that customer wants to upgrade his system with a few other nodes. Now those nodes will be placed 300-400 feet away from the closest existing nodes. To avoid two times the length of the data cable and in meantime losing some transmission speed , is it possible to connect at one point in the chain making a split connection and terminate that connection with bigger (say 1k) resistor after the last added node?
I know I could use repeaters for lengthening the distance and keeping the transmission speed, but I want to keep it ‘simple’ and not too expensive. I know some RS485 systems are allowed to use split connections (like LonWorks).
Will I need a repeater/driver anyway?
