4. Configure the hardware components as shown in Table 9-1.

5. Connect the RS-232 cable from the PC to the UART connector (J2).

6. Reapply power to the DC IN connector (J4). The PWR ON LED should illuminate.

7. Load the sample application program for the dsPIC30F3013 (see

Section 9.4 “Device Programming”).

* On this device, multiplexing of various peripherals on the pins does not allow the

simultaneous use of:

– Switch S5 and LCD.

– Primary UART1 pins and LCD.

Since only one DB-9 connector is provided for RS-232 communication, you can

select either UART1 (primary or alternate pins) or UART2, but not both.
