[Dxbase] Interfacing 2 radios

[David VE3VID]

I've had my Kenwood TS-450 interfaced with DxBase2007 successfully for a while, and I'm working on getting a second rig (TS-850) interfaced as well.  Question:  how does DxBase know which radio to draw data from?  Is it the check boxes under RADIO 1 and RADIO 2 tabs in the config areas?  Is there a quicker way to toggle between the 2 rigs?
Thanks
David
