Get your software updated to 4.11 and if that doesnt work send it in. You may have cold solder joints. If this has always happened since it was installed, check to see that youre going directly to a power feed or the battery. Sharing power on the same line as the dsm can cause this too.

It sounds like a software issue. If the depth still shows numbers and not dashes, that indicate that the DSM and trandsucer is working. Be sure that you have the most recent software for the E120 and for the DSM. You can find info about the current software and how to load it on Raymarine's website. It is important to perform a factory reset once the new software is loaded. If that doesnt solve your trouble, you will need to consult Raymarine's tech support dept.

In Speedometer 6y5-83570-s6 there are two black wires which is ground and which goes to fuel tank?


My Raymarine E80 depth display kept freezing up (display then says "DSM connection lost"). Of course, this seems to happen more often when entering a tight shallow anchorage in Alaska's inside passage. Raymarine tech support recommended that I update the display software and then update the DSM300 sounder software. I did this to no avail. Then Raymarine told me to install a dashboard mounted toggle switch inline with the positive power input of the DSM300 module so I could do hard re-sets (turning off the system power or powering down the displays does not reset the sounder module). This I did. Now when entering a tight anchorage, the display still freezes, but at least I can do a hard re-set with the new toggle switch and have the unit back up in about 40 seconds (a life time in a tight channel with the current running, etc.). Now, Raymarine says that if I send in the DSM module to them, they will replace it with their new circuit boards that solve this chronic problem that they have known about for a long time (hello, this is a significant safety issue - why no recall?).
Don't mess with this - send your DSM300 in to Raymarine!

I have a Raymarine C80 shart plotter / sounder with a DSM 300. I can't get the "status" light to come on and therefore I can't do a DSM reset. The fuse on the power input to the DSM was blown so I changed...


I would think it's prity much certain that the DSM 300 is duff. I returned mine back to Raymarine for test and repair £200 + VAT They came back unable to repair as they have no parts for the DSM 300 . They undertake to be able to repair units for up to 10 years and I think that's why they offered me a DSM 30 that will work with my analog display in my case a C70 MFDU and the existing transducer. OR an upgrade to a CP370 digital sonar unit, this will work on your existing tranducer but you will have to upgrade your display to a digital unit, I went for the upgrade and purchased an "a"series 9" MFDU with a chart, fantastic performance. This has left me with a spare analog MFDU that will hopefully keep my radar running a little longer before I have to go down that road and upgrade.
Hope this helps
PS there was no extra to pay so a CP370 for £240 was a good deal

I want to see the schematic diagram of humminbird fish finder transducer, my fishfinder won't operate. if i plug another unit of transducer, the my fishfinder operates normally.


Hi Greg and Ernesto:
Re-stating the obvious, your transducer is not working but you know that the sounder is.
I would start by checking to see if your transducer works on a different sounder. That's just a double check to confirm that it really is not working.
Then I'd try to isolate the problem:
- Plug (couold be corroded or damaged)
- wire (could be broken)
- Transducer (could be defective)
Since these are sealed units, I'd be checking with the supplier to try to find a replacement. Hopefully they are not too expensive, and time spent fishing is better than trying to maybe save a few dollars, especially if you're taking out charters.
Best of luck.

Raymarine "DSM connection lost"


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.

Sounder picture on e 80 freezes 20 min. after power on.


your feeling is correct on this it is still probably software! but also be aware that the power in connections are very susceptible to vibration and strains and once cracked inside they get a mind of their own. If this is a come and go problem that won't resolve, reflow the solder joints inside the DSM.

Raymarine E120, after 4h on display went dark in


blubaju, probably cold-cathode-fluorescent-lamp backlight failure! if unit dosen't have electro-luminescent style backlighting. All LCD panels require WHITE light to see what is on the screen!!! Is same common problem that computer (pc) lcd monitors suffer from!!! I suspect that if your unit has CCFL's, that the SMPS power supply or CCFlamp INVERTER circuit has a problem common to ALL LCD monitors. I should think that any BIG TIME tv/monitor repair shop could examine the printed circuit boards and effect a repair for you! Just mention that you think it suffers from the BLACK SCREEN of DEATH syndrome!!! Also mention that to RAYMARINE!!! when you call them and **** them out!! 12fixlouie .5hr nrth/wst of Windy City Rate this on fixya if this msg helpful??

Fish finder


You have either the DSM250 or DSM300 digital depth sounder module installed. The C80 is not seeing it.

There is an LED status light on the DSM. For starters, it should be lit either red, yellow or green to confirm it is actually powered on. We are hoping for a green light.

Double-check the cable between DSM and C80 for tightness. Also double-check the DSM's power cable for tightness.

The DSM's are sensitive to voltage level onboard. Make sure the DSM's connections to the circuit breaker panel or battery are tight and clean. Double check with a multimeter the there is 12V DC available to the DSM.

Let me know what you find.
