You need to contact sales@bentleywalker.com and ask for help.  If you have already signed up then the tech support number is +44 23 9231 1118.   They will provide you with a configuration sheet with your site ID, like BWHX99999, plus relevant satellite name, orbit location, polarisation, carrier frequency, symbol rate, IP addresses etc.

If you have taken over the dish from someone else clarify the details with BW and they will get you working again.  If the hub has downloaded new software to you then the BW hub staff should be able to see your status and put right any anomalies.

If you don't have a 505 marked on the feed throat then you have a feed different from most other HX sites.   If your dish is large enough and the feed is the correct type for the dish then you should be OK.  In your case you may have to rotate the radio assembly in its cradle to set the polarisation angle.
