Chris I just connected my Digirig to my IC-7000 via the 6 Pin DIN plug and it keyed up the radio just fine while using VARA HF. I monitored the audio on my HT and the audio was transmitted as well.
I do not have the CAT cable for the IC-7000 so I had to specify the com port in the optional transmitting section of the VARA setup. In my case it was COM10.
The 6 PIN DIN plugs are typically wired the same way on every radio, but HF only radios typically don't have the 9600 pin wired, or they use that pin for something else. Radios with 2 meters & 70 cm including all modes would or should have the 9600 pin wired for 9600.
Sorry I could not help any more, but hopefully you get it going.
