The RS232 interface is used for the device setup per PC (terminal program)and on-site firmware upload, using an RS232 to USB cable. Connect the device to your PC (which can be either Windows or Linux) and start a terminal program and select to the corresponding COM port. The device setup is managed at a serial baud rate of 9600 baud, which is the default for the majority of terminal programs.

Hit the ‘b’ key to set the CAN baud rate. The following screen will appear:
In this example, we hit ‘b’ to select a CAN baud rate of 500 kbit/sec.
c – Display Current CAN Settings
