    I am enclosing 2 configurations of a communication system on RS485. Can someone guide me as to which configuration is better?

    Figure 2 is closer to what the standad recommends but both can be used with the right repeater.

    Some RS485 installations can run up to 256 nodes in series...depending on Specs. I recently installed a Nurse Call system that does just that. About 70 odd nodes in the line, and another 16 nodes patched in via an RS485 modem radio link. No repeaters....works fine.
