Description of the Units<br />
The serial interface is controlled by the MB90F543 microcontroller.<br />
The bit rate is 9600 Baud. Set the user’s terminal / PC to this value. The bit rate of the CAN-CBX-AIR<br />
module can not be changed.<br />
4.2.3 Connection of the RS-232-Interface<br />
Below, the wiring of the serial interface is shown. The figure is used to explain the short terms of the<br />
signals as used in the chapter Connector Assignments. The signal description is given exemplary for<br />
the connection of the CAN-CBX-AIR to a PC.<br />
Note: For the connection of the CAN-CBX-AIR module to the RS-232 interface of the PC a<br />
nullmodem is necessary (if not already considered by the configuration of the serial lines).<br />
