Are terminating resistors required on my RS-485 network?
Not generally, and most of the time they generate more problems on the network. Our recommendation is to setup your RS-485 network without terminating resistors initially. If communication problems are seen which can be attributed to signal echoes or reflections, then a 120 OHM terminating resistor may be required on the RS-485 line.
