Raymarines RayNet to RayNet network cables provide a secure, waterproof means to link together c-Series and e-Series Multifunction Displays and accessories. The cables use the new RayNet-style waterproof ethernet connectors and mate to the Network ports on new generation c-Series and e-Series Multifunction Displays, CP450C CHIRP Sonar and HS5 SeaTalkhs Network Switch. The connectors are small-diameter to make for easy routing though the boat, but lock securely with a twist-lock ring.
