[CA] Simplify C120W System

I'm looking to simplify my current network and add a DSM300 to my C120W. This is how the network was when I purchased the boat and it functions OK. Given the C120W has 2 Seatalk HS ports, I plan on using those for the Radar and DSM300. My question is what is the preferred connection for the Raystar 120 since I will be eliminating the need for the Seatalk 1 to seatalk NG converter. Can I run it as depicted? or can I eliminate it all together (5-way and 12V) and run the GPS antenna directly to the C120W Seatalk NG Port?
