Figure 16: A complete RS422 interface.
A complete RS422/RS485 transceiver design connected to a bus system need to control the enable signals of the transceiver. The
SerialSelect signals are used for this purpose (see Table 13). The module need to be software configured to the corrected interface, see
the Serial Port Adapter AT Commands document how to configure the module to the correct serial interface. The Red/Mode pin is not
allowed to be pull-down when using the SerialSelect signals (see the
Table 13: SerialSelect signals combinations
