New boat installation Help

[Jazevedo]

Dear Members,

I'm preparing my new boat and purchased a lot of equipments and I will try install all myself. I would like to gently ask if someone can check if my installation diagram is right. Please find the attachment?

I'm installing;

1 A98
1 Ray VHf
1 Ais 350
1 p70R
1 Quantum Radar with cable
1 Evolution Sensor EV2
2 ECI 100 with volvo cable
1 Seatalk Network

doubt:
I need to connect 2 cables in EV2, 1 Spur cable, 1 Devicnet? Or only the spur cable to Seattle net?

the boat has 40 feet, and has 2 D6 EVC Volvo 370 newest model.

Anything wrong or suggestions? I need anything more?

Best

João
