[CA] [CA11] TRANSDUCER FOR MFD E7D

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum jose guilherme borja martins,

Q1. I installed an Airmar b164 1kw transducer Part Number: A80173. Does not work. MFD Raymarine cannot identify the connected transducer. What can I do to solve?
A1. During manufacturing, a tag identifying the transducer make, model, and product ID is affixed to the plug end of Raymarine or Airmar fishfinder transducer's cable. The product name (ex. B164, B319 B260, B744V, P66, P79, etc.) identifies a family of transducers rather than a single transducer, each of which is designed for a specific manufacturer and fishfinder or instrument product offered by that manufacturer. If supplied with a photo of the transducer's identification tag it may aid in determining whether your version of the B164 is compatible with an e7D MFD.

Q2. I have another transducer, P79, connected to a DSM 300 and this one connected to the MFD, working normally. Can I connect this B164 (A80173) to DSM 300 through any adapter cable? What would that cable be?
A2. See the response to Q1. If this is truly the A80173 version of the B164, then it should be able to be plugged directly into the MFD's Transducer socket. However, as the ax7/cx7/e7D/ex7/eSx7 MFDs only output 600W transmissions, the MFD's internal fishfinder circuitry will only support driving the B164 at 600W rather than 1kW.
