The logo will light up in one color or another depending on the clock source for the sampling the device is using.

Normally when the device works alone (-Stand Alone Mode-) the logo will light up in BLUE.

If the processor works linked to another unit and is working as a master (-Master Clock Mode-) the logo will light up in BLUE.

If the device works linked with another unit and is defined as slave (-Slave Mode-) the logo will light up in GREEN. The working mode is defined from the 3cMAP program in the Edit>Link tab .
