The product page doesn't make it clear that the shield has a removable lid. Once lifted off with a screw driver you have access to the solder jumpers referred to in the specifications. The units arrived with the internal switches controlling the attenuator. You need to use a soldering iron to convert it to using the serial interface. The attached photo shows the lid removed and the location of the jumpers J4,5,6,7.
ottimo si presenta bene , piccolo leggero si presta ad essere inserito all'interno di strumenti per arricchirne le prestazioni.
