The image above shows a typical use of the LR-232-x-x series of serial port daughtercards. In the center, the 4 port version of the daughtercard is shown plugged into the 6713 DSK. One port of this board is connected to a laptop, and can be used for control and monitor of the 6713's program. A second port is connected to another 2 port serial daughtercard (right), and can be used for DSK-to-DSK data communications.
