CONNECTING TO HOST PC FOR RS-232 COMMUNICATION

As shown in Figure 2-9, there are two ways to connect a PC to the PICDEM PIC18

Explorer Demonstration Board.

• Via the USB Port

• Via the DB9 Pin (RS-232 Port)

2.5.1

PC Connection Via DB9 Pin

To connect the PICDEM PIC18 Explorer Demonstration Board to a host PC via the

nine-pin DB9 connector, set jumper J13, as shown in the first illustration in Figure 2-10.

This routes the main microcontroller’s communications through a transceiver.
