The Serial Communication accessory board needs to be installed to run the following serial sam-
ple program in the
ing on your MiniCore model. This accessory board is included only with the Deluxe Development
Kit.
To install the Serial Communication accessory board, insert the strip of header pins included with
the accessory board into the socket at J12 on the bottom side of the Serial Communication acces-
sory board. Then line up the Serial Communication accessory board with the Interface Board or
Digital I/O accessory board standoffs/connectors and install the Serial Communication accessory
board pins into socket J2 on the Interface Board or the Digital I/O accessory board. Secure the
Serial Communication accessory board with the long plastic standoffs/connectors from above as
shown in Figure 3-6.
Pins 1–2, 3–4, 5–6, and 7–8 on header JP5 on the Serial Communication accessory board must be
jumpered. Pins 1–2 and 3–4 on header JP7 on the Serial Communication accessory board must
also be jumpered.

flow control on Serial Port C and data flow on Serial Port D.
To set up the Serial Communication accessory board, you will need to tie TxD and RxD on the
RS-232 header at J3, then tie CTS and RTS, also on J3, using jumpers as shown in Figure 3-7.
Once you have compiled and run this program, you can test flow control by disconnecting the
CTS jumper from RTS while the program is running. Characters will no longer appear in the
STDIO
window, and will display again once CTS is connected back to RTS.
