Icom M601 to Raymarine e7 via NMEA-0183

[Cardo]

I've tried (and failed) a few times now to get our Icom VHF to talk to our Raymarine e7 plotter. It should be fairly straightforward but try as I might I can't get any data from the VHF to the plotter.
The VHF receives GPS position via its NMEA input from a standalone GPS, so at least that aspect is working. If I connect this same GPS to the plotter, the plotter also picks up the signal, so I know the plotter's NMEA input is working.
However, when I connect the VHF's NMEA output to the plotter's NMEA input, nada, zilch, silence. The reason for this is I'm trying to get the VHF to pass position data to the plotter as a result of DSC position requests or distress calls.
The VHF's NMEA connections are via two phono connectors, one red for input and one white for output. As stated, the red one seems to be working fine.

I've checked diagnostics on the plotter when carrying out position requests on the VHF and it doesn't show any data coming in on the NMEA input. No erroneous messages, illegal messages, nothing at all.

The VHF only has one menu item for NMEA output, where I can select between "List stations", "All stations" or "Off". I have tried both List stations and All stations with no luck.

I have also remade the wiring connections a few times just to make sure, I'm fairly certain it's not my connections.

I'm sadly out of ideas!

Any thoughts?

If it's anything like my c series wide, you have to enable receipt of dsc/dse sentences on the plotter too: it's off by default. It'll be in the system settings somewhere: check the manual. I believe the "list stations" setting on the VHF will only send sentences generated by receipt of DSC messages from mmsis you've entered into your directory, so "all stations" is possibly what you want there (but I could be wrong about that).
