Raymarine forum

Greetings,

I wanted to see if this plan is 'doable' and I'm thinking about this correctly. Because I live on North Vancouver Island with no Raymarine support, I have to be pretty precise in my troubleshooting before sending parts out. I have a problem with depth reading coming from the DST800. I have an ITC-5, i70, and an a95 MFD.

To figure out if the DST is bad or there's a problem with the ITC-5, I'm proposing these actions:

1. Disconnect the DST800 from the ITC-5
2. Wire it directly to the i70.
3. Test it.

If good depth, transducer is go, chase ITC-5 or other problem. Bad/sporadic reading, replace the 800.

Does this sound right? And, before I attack the boat, can the above be done?

Thanks,

Rick,

It is not possible to do as you have suggested. Analog transducers must be processed by the iTC-5, or a compatible instrument display (ex. i50 Tridata, etc.) The i70 MFID has not depth/temperature/speed transducer processing within it.

Bummer. So do I have any options besides taking out the triducer and the ITC-5 and sending them in?

Rick,

I would only recommend sending the iTC5 in to be tested. When returned from Raymarine (without fault found or repaired), should the problem persist, then the DST800's insert should be replaced.

Thanks. That's the new plan.

Rick

You're welcome.
