DVLA50 extension in BlueOS

I’m integrating a DVLA50 but aren’t able to put the vehicle in the water just yet to test it. In the http://192.168.2.2/extension/dvla50 page, the DVL information is available, but the Status says waiting for cable-guy to come online… instead of Running. From memory, it should be Running, even if it’s not in the water - is that correct, and if so, what could be going wrong?
