Hi My Triducer has stopped sending a depth reading, the water temp and boat speed are still registering so it appears to not be a cable / connection issue. I have tried to remove the cable so that I can find out where the Simnet connection is but I can't get the cable out of the conduit that it goes in to under the fore cabin. It appears to go under the saloon seat as there is another grey conduit with 1 cable in that matches the conduit and cable from the triducer under the fore cabin but the cable feels stuck and won't move either way to check if it is the correct cable. Has any one replaced the triducer and if so where was the cable routed and the Simnet cable connected in to the Simnet system? Thanks Ken ------------- Ken 430e # 161 UK |

My triducer also just stopped sending depth data. There was about 1.5 meter cable coiled up and then a connector that looked like NMEA2000. Not the normal simnet plugs. My h370e is from 2008. -------------  Sea-U is a 370e #532 located SW Norway

| I have the same issue. Speed and tempature still available but lost depth. Some moments i receive a depth reading when starting the instrument but after some minutes the depth reading fails again? Anyone with a solution? |

After fiddling about with the cables, plugs and resetting the IS20 unit, I now get the depth for a few minutes when I 1st switch on but then it just decreases and goes to the no reading symbol. JG Tech have told me that the triducer comes with a 'comes with a micro c connector and I can supply an adaptor cable but am sure you are using one already if you check' so that sounds like I should also have a cable with a connector on coming from the triducer but I can't locate the connector and I think this is why I can't pull the cable through the conduit. The connector is stopping it! But I can't find the other end of the conduit, I will probably have to start removing the floor and seating to get below the floor. JG Tech also have IS20 Graphic Multi function instruments in so I may get one of those as well if it turns out that is faulty as well. Hanse could have made things easier by making the connectors available through an inspection hatch instead of hiding them. Ken ------------- Ken 430e # 161 UK |

If somebody of you have a spare thru hull fitting for the triducer, I would happily receive a PM! BR Thomas ------------- Hanse 312 MJ 2004 - Hanse 370e MJ 2007 |

If my new one comes complete with thru hull and it fits my existing through hull I will let you know and post it off to you. ------------- Ken 430e # 161 UK |

Same here, I lost Watertemp, but still have speed and depth. Can't find the connector on my 345 ------------- Frank |

In my H350 (2010) the first connector is located under the front cabin bed, near the waterpump. From there the transducer cable is routed first behind the port locker of the front cabin, then through the compartment under the port seats of the main cabin. I found the cable in the space between the box that contains the batteries and the front of that compartment. I had to take out the loudspeakers in that front before finding ( with the help of a light and a mirror) the cable and a second connector. Maybe this can help you finding the transducer cable/connector in your boat? Claude ------------- JUTTER, Hanse 350#0256, 2010, deep keel, Zeeland |

I don't think that the missing reading is caused by any cable problem. I had the same problem on my 2008 Hanse 350 last year: no reading for depth while temperature and speed were properly displayed. My technician diagnosed a defective transducer. The triducer had to be replaced, which is quite simple. Since then the problem didn't reoccur. Boris

| Boris could you change the transducer with the boat in the water? |

Yes, that is quite easy. You just need a piece of cloth and the plug to replace the transducer. Turn the nut holding the transducer in place. Pull the transducer out and replace it by the plug. The thru-hull has sort of a simple valve, so just a little amount of water comes in (maybe 200 ml max, thus the cloth). Besides: a reason for failure of the transducer might also be vegetation or mussels on the hull (wasn't that in my case). That's why my technician recommended pulling the transducer whenever the boat is left unmoved in the harbor for a longer time. Good luck! Boris ------------- SY Ginosaji Hanse 350 #230 |

Changing the transducer should be the same as cleaning the log, once you have fitted the blank plug in the hole you can replace the transducer and then refit the new transducer in the hole. Just the 1/2 lt of water to mop up. ------------- Ken 430e # 161 UK |

It is the same, as at least for the 350 Hanse uses a three-in-one solution for temp, speed and depth. ------------- SY Ginosaji Hanse 350 #230 |

I am trying to order new. Need to specify what plug. What type is the plug on the triducer. It looks like NMEA2000. See picture. The other plugs on my boat looks like simnet plugs.  ------------- Sea-U is a 370e #532 located SW Norway

Sea-U: Could this be a misunderstanding? I meant the plastic plug replacing the triducer when taken out of the thru-hull. Boris ------------- SY Ginosaji Hanse 350 #230 |

You will find the DST transducer has a short cable with Micro C / NMEA 2000 plug. This connects to the existing NMEA backbone. You should find the connection in the floor space where the transducer is located. The backbone cable probably runs to a multi simnet connector near the chart table, but you don't need to replace that. ------------- H458 #159 Primal Mediterranean cruising |

Presuming that the same transducer and lead are fitted to all models can anyone tell me how long the transducer lead is from the transducer to the plug. This may help me locate the plug connector on my 430 as it is not under the floor by the transducer fitting as the cable disappears under the saloon floor in a conduit? Thanks Ken ------------- Ken 430e # 161 UK |

Mine is about 1 metre but is coiled so the backbone connection is only about 30mm from the transducer and very visible. The backbone then runs aft into a stringer and from there appears to be inaccessible until it emerges near the main switchboard. ------------- H458 #159 Primal Mediterranean cruising |

Hi New triducer fitted and new IS20 graphic display fitted and all is now working. The cable routing was difficult to locate but eventually I traced it to behind the forward cabin hanging wardrobe. You remove the back and there you will find the Simnet cable connection unit. The connector on the cable from the triducer NME2000 to Simnet was jammed in to the conduit below the forecabin floor to behind the saloon seating where the shrouds are connected. It took a bit of pulling and shoving but eventually we freed the cable and replaced with new. Ken ------------- Ken 430e # 161 UK |

Hi, I have a similar problem on my 370e of 2006: I have a IS12 Combi instrument fed by two "analogue" cables - one for the depth transducer and one for the speed/temp transducer. As I have bee unable to find a suitable replacement i bougt a triducer with NMEA 2000 connection and plan to replace the Combi instrument with a Data instrument. My problem is to get the new cable to the area of batteries/navstation where I have some spare backbone/Simnet connections. There is a light grey conduit under the fore cabin floor, but I can't find out where it ends. The present cables goes all the way to the steering pedestal but behind the SB aft cabin you can only see a couple of black conduits. Does anybody know where the light grey conduit ends? ------------- BÄSK, Hanse 370e #82 from 2006, Yanmar 3JH4E/SD50, 3-blade Flexofold, RMC(Lewmar) 185 Bowthruster, Vulcan 9, Simrad+B&G instruments |

Thanks Ken, I actually found the cables and the Simnet connector behind the wardrobe, but I had to remove the whole wardrobe to be able to lay the cable hose. It was a lot of screws to remove but when that was done it was very visible and easy to fix. If you do this - don't forget to also remove the hinges as these screws goes a little bit out on the other side. At the same time I made a 230V connection to a outlet. As told in this forum Hanse left these 230V cables unconnected if the outlet option was not chosen. In the picture you can see the Simnet connector (high up) and the light grey 230V cable to the right as it was before my additions.  ------------- BÄSK, Hanse 370e #82 from 2006, Yanmar 3JH4E/SD50, 3-blade Flexofold, RMC(Lewmar) 185 Bowthruster, Vulcan 9, Simrad+B&G instruments |
