topfield 7700 pvr + diseq 1.2 motor

[pierlu1]

Hello, i've just bought a wonderful 7700 pvr and my problem is this.
I have a gibertini dish of 150 cm offset, an actuator of 24 inch and a supertrack positioner to link the actuator to a normal lnb cable by diseq 1.2.
I've read on the characteristic of topfield that it has diseq 1.2. The problem is that on the osd of the receiver i don't know hot configure my positioner. I mean that i can see the possibility of having diseq 1.3 usals and the diseq 1.0 and 1.2 with fix lnb, but the supertrack must be connected to a diseq 1.2 with the function of moving my dish without usals, ex. diseq 1.2+ motors as in topfield 7700 hsci menu (supertrack doesn't recognize usals). Is it possible and how ?
Many tks in advance
Bye
