9.1 Application Information

Figure 7 shows a typical RS-422 application. One transmitter is able to broadcast to multiple receiving nodes connected together over a shared differential bus. Twisted-pair cabling with a controlled differential impedance is used, and a termination resistance is placed at the farthest receive end of the cable in order to match the transmission line impedance and minimize signal reflections.
