WebIf you use more modules along the network you need to remove the 120 ohm resistors (R7) on those intermediate modules. The 20K resistors hold a known signal when no one is transmitting. Example RS485 Network Diagram: (NOTE: The 470 ohm resistors shown below are not needed with the modules above) AMMAN, Jordan. WebNot 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. Attachments WebShopping Lists.

"WebIn most cases termination is not required. There are several methods of terminating data lines. Most commonly used is a parallel termination. A resistor is added in parallel with the receiver’s “A” and “B” lines in order to match the data line characteristic impedance specified by the cable manufacturer (120 ohms. is a common value).
