First go to File->Open. Embedded Setup comes with a folder called “Configs” in its installation path. Open the most appropriate to your hardware.
Note: It is always better to prove that the device as-shipped is operating according to the default setup. Making changes to the device before it has been seen to work leaves the user in the position of not know where to look for issues. e.g. is it the configuration of the Pilot, the cabling or the downstream system cabling or its configuration.
Yellowcog configuration files are ASCII in format but not generally editable by hand. They are saved as “ycd” files and best edited in the Embedded Setup program. It can be useful to associate “ycd” files with the setup program using the Window “Always open with” feature.
