Raymarine - e127 and e97 sonar/fish finder transducer problems

[Ian_Edwards]

I've connected a P319 Airmar transducer to a Raymarine e127. However, the e127 isn't recognising that there is a transducer connected.

The P319 is listed in the Airmar cross reference table as being compatible with the the sonar version of the e127 and e97 and came with a plug which connects directly to the e127, no need for a patch cable.

Does anyone out there know if I have to enable (switch on) the e127's internal sonar system? And any ideas on how an e127 recognises that a transducer is connected?

The P319 is a dual frequency (50 and 200 kHz) 600 watt transducer with a built in thermistor ( or at least I think it is probably a thermistor) to measure temperature.

I've contacted Raymarine's help desk by email, but no reply as yet.

Re: Raymarine - e127 and e97 sonar/fish finder transducer problems UPDATE

This is the information I got from Raymarine, the text in italics are my comments.

With this info' I will be able to test if I get a short between pins 5 and 6, which should let the e127 know there's a transducer attached. I'll also be able to check that i get the correct resistance from the thermistor. and then take it from there.

There are three models of P319 sonar transducers…..

A80171 Suitable for a/c/e/es model 7 MFD’s – this is the one for your e127. From the AIrmar cross reference table this is a Airmar 31-323-8-01
E66013 Suitable for Axiom DV/RV and CP370
E66077 Suitable for Axiom DV/RV and CP370/470

I have an Airmar 31-323-8-02 - Raymarine Airmar P319 DT 6/9M Pin 600 Watt Thru Hull Transducer 10 Metre Cable. I'm assured that this is the correct transducer, The 02 at the end is just a revision number.


Transducer detection is typically made via the sense wires . As a cross check you can measure the resistance across the pins to assess if this is functioning.. See the attached image.

The “select sonar transducer” can be found in the menu ..

It should scan and advise what transducer it can see.

I've already done this and the e127 can't find the transducer.
