[CA] [CA11] Axiom and Transducer Y Cables

[Chuck - Raymarine - Moderator]

mannery,

Raymarine offers Y-Cables permitting an Airmar 600W or 1kW transducer to fishfinder transducer to be simultaneously interfaced to a single Axiom RV MFD or Axiom DV MFD along with a RealVision or DownVision transducer respectively. However, thermistor lead within the currently available Y-Cables are connected to the Airmar transducer and no electrical path is provided to the RealVision transducer's thermistor. This may be an oversight, as the Airmar manufactured P79 is commonly used with these MFDs to support monitoring depth at higher boat speeds and to support 200kHz and 50kHz sonar imaging. This has recently been brought to the attention of Raymarine's product management who will be considering a change to the design of these Y-Cables to provide and electrical path to the RealVision or DownVision transducer's thermistor instead of the Airmar manufactured transducer's thermistor.

In vessels featuring only one Axiom MFD having internal fishfinder sonar, this limitation may be overcome by interfacing a NMEA 2000 Smart temperature transducer or NMEA 2000 Smart speed/temp transducer to the system. For vessels featuring more than one Axiom MFD having internal fishfinder circuitry, it would be recommended that the RealVision or DownVision transducer be interfaced to one MFD and that the Airmar manufactured transducer be interfaced to the second MFD.
