3.2 Serial Interface
3.2.1 Default Setting
The default setting for both serial interfaces is the following:
Bit rate:
9600 Baud
Data bits:
8
Parity:
no
Stop bits:
1
Handshake:
none
3.2.2 Configuration
The serial interfaces are controlled by the microcontroller PowerPC405GPr. The bit rate of the
interfaces can be configured. The serial controller integrated in the PowerPC405GPr and the RS-232
driver used for interface SER 0 support bit rates of up to 115.200 kbit/s.
The bit rate can be changed by means of software. The procedure to change the bit rate depends on the
operating system, it is therefore advisable to refer to the manual of the operating system.
