4.3 Dual Port FT232 UART Interface Mode Description
The FT2232H can be configured in similar UART modes as the FTDI FT232 devices. The following
examples illustrate how to configure the FT2232H with an RS232, RS422 or RS485 interface. The FT2232
can be configured as a mixture of these interfaces.
4.3.1 Dual Port RS232 Configuration
Figure 4.1 illustrates how the FT2232H can be configured with an RS232 UART interface. This can be
repeated for channel B to provide a dual RS232, but has been omitted for clarity.
