Adding 2nd HDS Live to console

[Kromer]

I have the AT 2 and HDS16 installed for the bow, all thats left is adding the 2nd HDS 12 at the helm.
On other posts I have read that I only need to connect the ethernet cable between the 2 graphs and even thought that might work, as I try to think that process through I would also need power to the 2nd HDS 12, yes?

Yes each unit needs its own power
