GPSDO Not Detected by SmartSDR

I just installed a DOGPS module in a reconditioned Flex 6500 just purchased from the factory.  I'm using the latest SSDR -- 2.2.8.  The DOGPS unit had worked FB previously in another Flex radio.  When I say previously, I mean like two weeks ago.  However, SSDR says it's not present.  When I power down the 6500, I get the orange glow light, which I believe I read indicates that the radio knows the DOGPS is there and is keeping it powered while the rest of the radio is powered down.  So, why is SSDR not recognizing the DOGPS module?

The 6500 is hard wired to the LAN, and the computer (MS Surface Book Pro 2) is connected via WiFi.  SSDR has no trouble finding the radio, and I have no trouble connecting to it.  SSDR just doesn't see the DOGPS.

I have tried to a 6500 reset, but that has not solved the problem.  

What else should I try?

Thanks for any help anyone can give me.

Well, guys, I followed both suggestions and the GPSDO is now recognized and is working FB.  There were a few anomalies during setup that I think I should report.  First, when I turned the rig back on after replacing the bottom cover (I had tested it first briefly with the cover off), it blinked orange for several minutes, then blinked blue for several more minutes (much longer than usual) before turning solid blue.  In fact, it did not turn solid blue until I ran SSDR, and viewed the GPS setup window.  I did not actually click install or anything.  It reported right away that "GPS is active" and was displaying the correct Grid Square, altitude, etc.  

A few details on my work: 1. I actually used a very small dab of DeoxIT rather than alcohol; 2. When I first turned the rig on for my bottom-cover-off-test I had the 6500 upside down, it would go through the calibration routine and then automatically shut down. I did this several times, always with the same result.  It would not actually boot up.  I then decided to put it right-side up, still with the bottom cover off, and voila it booted OK.  Is this standard behavior?  Does it have a sensing mechanism for its position?  

Thanks, again, for the suggestions!
