[TenTec] ORION2_SteppIR_Interface

[G]

I was hit with lightening the other day and my O2 to SteppIR control box are no longer on the same page. Normally, when I change the O2's frequency the SteppIR box changes the beam to the same frequency.
After the jolt by Mother Nature they aren't talking.
The SteppIR box works fine in the manual mode.
My question is. Is there a free down load O2 program I can run and control the O2? I can take the DB9 off the SteppIR box and connect it to the computer to see if the computer talks to the O2 to prove the O2 or the SteppIR box.
Or is there an easier way to prove the O2's interface isn't the cause.
Thanks.
