Outdoor Generator Ethernet to Orbi

I have the AC3000 RBK53 Orbi with 2 satellites up and running inside the house with no problems.  I recently set up the outdoor satellite- RBS50Y- but now I am afraid it will not be able to help me.  We have a standby generator outside with an optional remote management setup that is wired for an ethernet cable (Cummins C20N6HC).  I had not realized that the RBS50Y satelite does not have an ethernet port like the other satellites.  Is there a solution to this?  Would a wireless bridge help and if so what model?  Thanks!
