RS-232 COMMUNICATION
1 1 3 3
RS-232 communication enables point-to-point data transfer. It is commonly used in data acqui-
sition applications to transfer data between the microcontroller and PC. Since the voltage levels
of the microcontroller and PC are not directly
compatible with each other, a level converter
such as MAX232, must be used. In order to
provide more flexible system, the microcon-
troller is connected to MAX232 via jumpers
J12 and J13 for RS-232A and jumpers J14 and
J15 for RS-232B. The jumpers J12 and J13 are
therefore used to connect Rx and Tx lines to
RF2 and RF3 pins, whereas the jumpers J14
and J15 are used to connect Rx and Tx lines to
RF4 and RF5 pins.
