The transverse feedback systems for controlling the vertical coupled-bunch instabilities in the positron and electron Dafne main rings are installed on site. They started to be operative from June and September 2000. For the horizontal plane similar systems are ready to be installed. Design specifications and the basic system concepts are presented. Real time bunch-by-bunch offset correction is implemented using digital signal processors and dual-port ram's. Fast analog to digital sampling is performed at the Dafne Radio Frequency (368 MHz). The system manages at full speed a continuos flow of data and it has the capability to invert the sign or put to zero the output for single or multiple bunches in real time. A conversion from digital to analog produces the output correcting signal.
