No the 3225 collars will not work on the 3200 system.
Just like the old system had the compatibility of running the collars on 400, 800, 1200, and etc transmitters..... the new system collars only work with the new system transmitters - 1225, 1825, 2525, 3225 transmitters.
I had to sell all my transmitters and collars when I went to the 3225 for the lack of the non-compatibility.
The new system collars are in charging cradles like TT and can be fully charged in 2 hours. They are also now on 3/4" collars instead of the 1" collars.
