Upgrading older system...

[FishBut]

Hi, I am upgrading an older C80 Raymarine system with two E120W displays. I plan to use a Raymarine Ethernet hub, DSM 300 sounder module, P66 transducer and digital radome. I have a couple of questions regarding the GPS receiver. I have a Raystar 120 GPS receiver and trying to understand if this will work with my new setup. If so, I need some information on how to connect the 120 to the network. I have read the E120W manual and sounds like I can use NMEA 0183 for this connection, correct? Is this the best way to do this? Or should I consider upgrading the receiver to the 130 or something similar?

Second, I see in an install diagram that it appears the radome can be wired directly to the Ethernet hub with the HS cables. Is this correct? Or does the radome need to be wired directly to the master MFD? If so, what would the ideal connection to the MFD as the Raynet HS connection will be used for the Ethernet hub?

Thank you!
