Raymarine depth instrument

[charmedquark]

Hello,
I have 2 instruments reading depth. One raymarine i50 depth gauge at the lower helm and an i50 tridata on the flybridge.
The chart plotters also displays depth.

I don’t know if I pressed a button and it did something but I suspect I changed the master and slave config somehow because the lower helm one displays depth but flashes “LAST” and the upper one displays “- - -“
This started last weekend.
As I said the chartplotters seems to be displaying depth fine.
Any ideas what the issue might be and how to fix it?
Thanks

I should add that going into the MFD data sources setting shows that there are 2 devices on the network that are stopping device selection working. I wonder whether it’s possible the VHF (icom 550bb was off which might cause this) or whether something- probably expensive - has failed. Worked fine until Sunday morning so I suspect I might have caused the issue by fiddling

Does the system include an iTC5 ? If so, that would stop selecting the depth transducer, but unlikely to be the issue if depth is shown everywhere else. You may be correct, it's something you have done. Try swapping the 2 displays.
