German Sport Guns TV presents a two-part video of the Ares ARES Electronic Firing Control System (EFCS) which is basically a two-part system, the first one is an Ares AEG that has the EFCS installed in the gearbox and the second one is the Gearbox Programmer which is an external device that allows anyone to set the firing modes of the EFCS AEG just using knobs in the programmer. This video is in German so just turn on the captions.
