Some examples of connecting external equipment are shown in Figure 2-23.
2.4.3.4.1. RS-485 Transmission Line Termination
The RS-485 network should include a terminating resistor, installed between the two lines at or on
the last node. The terminating resistor should match the characteristic impedance of the
transmission line, approximately 120 ohms. This terminating resistor is required when connecting
ARM100 modules to the port.
