System Upgrade

Don,

Q1. I called AIRMAR and order the mix and match cable for the CP370 (on it's way). Is the difference in connectors because one is 1000W and the other 600W?
A1. Transducer model names B250, B744V, P66, etc. are actually transducer family names. Airmar produces variants of these transducers designed to match the circuitry requirements and plug style of the supported fishfinder manufacturers and their fishfinding products. In contrast, Airmar's mix and match transducers are a generic design which Airmar makes function like the aforementioned variants through use of a Mix and Match Cable. Should one own an Airmar branded transducer, then it is always recommended that Airmar, Inc. ((603) 673-9570) be contacted for advice when seeking to use the Airmar transducer which had been previously used with a third party fishfinding product instead with a Raymarine fishfinding product.

Q2. Is it ok to have the CP370 go to one RAYNET connection and the radar unit to the other on the back of the ES97. It seems reasonable to me but there are lots of diagrams with a switch with only 2 Raynet connections.
A2. For systems featuring more than one MFD, it is quite common to recommend that all compatible devices having an Ethernet communications interface be interfaced to the system's MFDs via an Ethernet network switch (ex. HS5 RayNet Network Switch, etc.) for redundancy purposes and the ability switch off MFDs not needed while operating others. In systems having a single 9" or greater a/c/e/eS/gS-Series MFD or Axiom Pro MFD, it would not be necessary to install an Ethernet network switch unless more than two compatible devices having an Ethernet communications interface need be interfaced to the MFD.
