4.8 RS-232 Serial Port
The DE1 board uses the MAX232 transceiver chip and a 9-pin D-SUB connector for RS-232
communications. For detailed information on how to use the transceiver refer to the datasheet,
which is available on the manufacturer’s web site, and from the Datasheet folder on the DE1
System CD-ROM. Figure 4.16 shows the related schematics, and Table 4.10 lists the Cyclone II
FPGA pin assignments.
