First commissioning steps
Preface
These instructions use a concrete example to guide you through the four commissioning
steps and up to a functioning application with which you can transfer data via the serial
interface and get to know and check the basic functions of your CP 340 in hardware and
software. The references to the manual should give you an initial overview of the information
included within it.
The time required for the example amounts to between 1 and 2 hours, depending on your
experience.
