programming radio with FSUIPC

Hey,

I have another question concerning the offsets of FSUIPC.
If I have pushbuttons and a rotary, is it possible to simulate the radio of an aircraft?

I want to realize a little radio section. With the pushbuttons I select the frequency I want to change and with two rotaries I change the frequency.

Are there any offsets to realize that with the FSUIPC? I use the BU0836X card and have serveral pushbuttons and two rotaries connected. How can I select a source and how can I change the frequency? Is there a radio increament and decreament? The only thing i Found was a COM incrament and NAV increament but I only have to rotaries. Is there any solution?

A last pushbutton is used to swap the frequency between standby and active.

Finally, it should work like the Radio Management Panel of an Airbus.
It would be perfect if I can change NAV1, COM1, ADF1 and XPNDR

Is it actually possible to use a Software to program such ideas? I know SIOC, but can SIOC work with other hardware then IOCards?

Is there a way to use SIOC with the BU0836x?

A lot of questions, I know, but I hope you can help me ;)
