Current best practice for controlling chase bliss pedals?

It seems like there have been updates to firmware over the years so thought id check before i ruin something

Im currently running MC8 into morningstar midibox.

It looks like i need to change the jumper inside the midi box to ring only. Do i also need to physically remove the tip from the TRS cable? Or is that the old way of doing things?

I also saw you can use the trs splitter to just plug into the ring?

Any help or insight would be appreciated. I dont want to ruin the generation loss mkii befoew i get to try it with midi lol
