Dff1-UHD no bottom

[Fish_Hunt]

I added the Dff to my tzt3 sysytem and wired in the B265LH. I am not getting bottom nor anything else. Temp shows up.
The LED indicator flashes at approx 2sec.

Using the B265LH is a great pairing for that fish finder. I think you missed pulling back the cable shield and wrapping it around the wire to put under that metal hold down clamp. (or it isn't viewable)



This is VERY important.

That metal clamp is more than just a cable hold down; that is your transducer grounding.

I noticed that. Will change and report back. I did not install the system, just purchased the boat.

I pulled back 3 shields and wrapped them so that the clamp is in contact. Still nothing. The shields were foil like, not the mesh in the manual.
Here are some more screen shots of settings

And a few more.
How do I test the transducer?

Here are some thoughts after looking at your screenshots.


FishFinder must be in "transmit" to see any signals


You have an active instance conflict between two devices both putting out heading PGN data to the bus.
Recommend you change the PG700 to instance 1.


Recommend using your best item as primary source. Use SCX30 for date/time and also for POSITION, HEADING, MAG VAR


Software version on the DFF1-UHD looks perfect.

If you turn on the transmission of the transducer in the water and not working; then testing the transducer would be a good idea. This needs to be done with an Airmar TDT1000 transducer tester (normally done by your installing dealer) or send in the sounder to have it tested.

Thank you. I did not notice the conflict.
I had the transducer tested and it's good. Will try your other suggestions soon. At this time I bypassed the Dff for a fishing trip. It works fine on the tzt3.
