RS-232 Serial Port
The Spartan ? -3 FPGA Starter Kit board has an RS-232 serial port. The RS-232 transmit and
receive signals appear on the female DB9 connector, labeled J2, indicated as 6 in
Figure 1-2 . The connector is a DCE-style port and connects to the DB9 DTE-style serial port
connector available on most personal computers and workstations. Use a standard
straight-through serial cable to connect the Spartan-3 Starter Kit board to the PC’s serial
port.

Figure 7-1: RS-232 Serial Port
Figure 7-1 shows the connection between the FPGA and the DB9 connector, including the
Maxim MAX3232 RS-232 voltage converter, indicated as 7 in Figure 1-2 . The FPGA
supplies serial output data as LVTTL or LVCMOS levels to the Maxim device, which in
