21 / 63 page  Copyright © 2010 Future Technology Devices International Limited 21 Document No.: FT_000061 FT2232H DUAL HIGH SPEED USB TO MULTIPURPOSE UART/FIFO IC Datasheet Version 2.09 Clearance No.: FTDI#77 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.
