8.1 Setting up a Serial Connection
The CDI interface of the COMS-Module is a UART interface
(asynchronous serial interface) with 3.3V CMOS signal level.
If you connect a switch with level converter (e.g. "EXAR -
SP3232EUEY") to the application connector via the RX and TX
connections of this interface, an RS232 interface is available to you
for connecting a terminal (you can find details from our sample circuit
diagram under "RS232 Interface for CDI" in the Appendix).

Setting up a Serial Connection
You can connect the serial COMx interface of a PC to such a
terminal interface (or a serial USB converter) and then access the
CDI menus using a terminal emulation. We provide you with PuTTY
as a terminal emulation on our support webpage.
