Digirig cable connection

I need to see the 3.5mm connection locations, I have tried several combinations without success
I have a IC 2730 mobile

The matching cable for your radio is this one:

The page also contains schematic for the cable. If you need to look up the cables for any additional radios then please use list in this page:

So the “serial” port is unused. And I have the RJ-45 cable I bought the kit

There is no store cable for that. See other discussions for information on connecting CI-V in this radio: Topics tagged icom-ic-2730

Thanks for your help
