C97 networking question?

I recently purchased two C97 units. I also have an Airmar B60 transducer with the RAYA connector, and a RD424HD radome unit. I want ot hook everything up and be able to access all features on both c97 units.

Do I need a hub, and if so which one? could you explain which cables I need and the best way to connect these?

At this time, I do not have any immediate plans to add any additional equipment.

thank you!
