NETWORKING/RADAR question

[tonyiiiafl]

I am now the proud owner of Raymarine e127 AND Raymarine e97 multifunction displays. I also purchased the CHIRP T70243. I am just a novice at installation and networking, so I need to ask a question. To properly network these two devices, I would ASSUME that I will need RayNet switch A80007. I would then (?) run my CHIRP radar cable to this switch, then run cable A62361 to each display? Where this is a wireless radar, I assume I could use the WIFI, but it would not be as quick as the wired connection?

Lastly, I am using transducer B744V, with adapter cable E66066, which plugs into the back of the display. Is there a different adapter cable that will run to the RAYNET switch so I can share the transducer? Or how would I (in layman's terms) share the transducer? What NAVIONICS Platinum+ chart would I use for the waters from Maine to say New Jersey?

MANY thanks for the help, and I am SO proud to have the latest and greatest electronics on my Carver!
