The Consumer-band BPSK 7.2 kbps PLM PICtail Plus Daughter Board incorporates Analog Front End (AFE) circuitry, which is required to implement a software-based modem, using the dsPIC33F Digital Signal Controller (DSC) device on the Explorer 16 Development Board. The daughter board fits into the expansion slot on the Explorer 16 Development Board. A HV adapter cable (included in the package) interfaces the daughter board to the power line. The HV adapter cable incorporates the circuitry required to provide noise-filtering and isolation from the power line. The daughter board and the HV adapter cable are designed to operate at a carrier frequency of 129.6 kHz (CENELEC-C band).
