Table 3.8 Pin Assignment for expansion ports
3-9 Using the Serial Ports(RS232)
The DE2 Board uses the standard 9-pin D-SUB connector for RS-232
communications between PC and the board. The transceiver chip used is MAX232.
For detailed information on how to use the chip, users can refer to the spec under
C:\DE2\Datasheet\RS232. Figure 3.11 shows the related schematics. The pin
assignment of the associated interface is shown in Table 3.9.
