That is only for SeedCommand.  You would have thunk they would have made it for both right??

I would guess they already had the Insight on a planter controling the Rawson Drive and now moved the drive to the dry box.

I have this setup in my tractor and serial cabe control the rawson drive through the rawson processor to run my dry box.

Also if this guy has not got a processor, I think I have an extra one.  I will try and email him.
