4.4 Serial communication prototcol
4.4.1 Use
The AOL0223X can be driven with a serial communication protocol: the Hirose 12-pin cable includes
3 pins dedicated to RS232 serial interface. The following table summarizes the connector pinout
and pin functions (for pinout numbering refer to Paragraph 11.1):
Pin number Pin name Function Cable color (for CBGPIO001) Connect to
7 RS232_GND Ground reference Brown GND
8 RS232_RX Data receiving pin White USER_RS232_TX
9 RS232_TX Data transmitting pin Black USER_RS232_RX
The electrical characteristics of the RS232 transmission protocol have been described in the
“Connection” chapter: please refer to paragraph 11.4 before starting a new connection through
serial interface.
