Raymarine "DSM connection lost"

Hello,

I have a Raymarine E120 with a DSM 300 connected to an Airmar B258 thru-hull transducer. The system worked fine for the first 2-3 years in boat, but in the last year or so I have been experiencing the following problems;

Sometimes lose depth reading, screen freezes and "DSM connection lost" is displayed on screen along with an audible alarm. (This occurs at all speeds & depths).
Sometimes unplugging & replugging cables @ the DSM restores connection but not always.
Occasionally the screen will freeze without any alarm or messages displayed.

I don’t think voltage or current to the unit is an issue & I have replaced the cable between the DSM & the SeaTalk hs Network Switch & installed the most recent software.

Thanks,
Murray

Murray,

Has the DSM and the E120 software been upgraded to the latest software: 4.12 for the DSM and 5.52 for the E120?

Try this first. You can download the software off Raymarine.com and burn each to a separate compact flash card.

I have seen many problems like you are experiencing solved with this simple change.

If this doesn't solve the problem, the DSM will have to go back to Raymarine for repair.

Will the speedo work on an Airmar ST850 with only the green wire connected

You'll need three wires connected.
The green is the signal from the ducer, the red provides power to the ducer and the bare wire is common ground. See the link I've provided for more info.
Hope this helps.

WHAT TRANSDUCE GOES WITH THE DS600X COLOR ..WHERE CAN I BUY ?

Hi
Airmar makes almost all of the transducers for Raymarine. From the Airmar FAQ section, your unit is listed. See the link below. Pretty much any marine chandler or Raymarine dealer should be able to order it for you.

My marine speed transducer needs to be replaced. I have a Beneteua 351 which is 16 years old. I have cleaned the transducer several times and then reinstalled. It will work for a couple of minutes and then...

Yes. You need to make sure you get the same transducer though. With you system being that old, you may have a transducer that is old where there is not a direct replacement. You need to make sure you get the correct transducer. You may need to get a "flapper" kit to update your housing to the new style.

Contact Raymarine or your nearest Raymarine dealer. Raymarine normally has those things on their website although it's a bit cryptic to find sometimes.

Raymarine ds500x brand new works good but will give false bottom readings occasionally corrects itself fairly quickly 30 seconds to two minutes wondering why it does this and how to correct it

If the transducer is not correctly mounted this may happen due to air, etc. If the unit never gives a depth reading that looks like dashes
( - - ) then there is likely nothing wrong with it aside from the transducer placement.

I was looking to see if I could find a replacement for the display and was able to confirm that the transducer is a single beam 120khz unit so I doubt that you've find a replacement for it ..as is .

The Airmar C-49 is the proper number for the connection line but like me I think your going to have to think about a whole new unit and or system . Been there already.

Best of luck.

Depth sounder

the transducer has to be in the water or attached to the inside of the hull if fiberglass with no air between the hull and the transducer. It doesn't transmit thru air.
