Xcom-232i-Setup

The Xcom-232i is a bridge for the RS232-BUS to the CAN-BUS. The test-programms for the Xcom-API-Class will ask you for the baudrate. So it is essential, that you know the baudrate of the Xcom-232i, otherwise the communication between the Raspberry Pi and the Xcom-232i will fails. The standard baudrate for the RS232-BUS is 38400, but you are able to change this value to 115200. To do that you need the Xcom-Configurator, which is only available for a windows operating system.

Download-Link Xcom-Configurator: https://www.studer-innotec.com/media/document/0/xcomconfiguratorsetup_1.0.26.0.zip

The picture below shows the Xcom-Configurator program.

After downloading and installing the Xcom-Configurator, you are able to change the baudrate:

• Remove the Micro-SD-card from the Xcom-232i and insert it into your PC.

• Start the Xcom-Configurator.

• Choose the SD-Card-Drive, where the SD-Card of Xcom-232i is located.

• Choose a Xcom-Mode, which is either "232i (38400 bps)" or "232i (115200 bps)".

• Finally click on the "Generate" button and a new configuration-file will be stored on the SD-Card.

• Remove the SD-Card from the PC and insert it into the Xcom-232i.

• The LED of the Xcom-232i should be now blinking red. This indicates, that the Xcom-232i is updating. The update is finish, when the LED is blinking green. The baudrate of the Xcom-232i is now set.

Note: More Informations about the LED-state can you find in the documentation of the Xcom-232i under the section: Hardware Information.
