A clone is a receiver physically built like the original. In the case here we are talking about genuine Pansat 2700 clones, which use either nnnv1 Tivo BINs or n0nn Vortex BINs
A converted receiver is one that was build as something else, e.g. Pansat 2500A, Fortec Ultra, Pantec and other Pansat 2500A clones. After conversion it behaves like a Pansat 2700A, basically because of specially modified software. These files are jvvh_nnn or CS_nnnT_lightning. There are others who make modifications - at present I know of Saif and Lothario BINs which are almost the same as jvvh_ BINs.
