JD 7000/7100 planter milo settings

I have a 7100, 12 row, 30" planter that is a plateless planter. I'm planning on planting 6-7lbs an acre at 15k-16k seeds per pound. I've never planted milo before so I'm going to have to buy the low rate feed cup or the regular rate feed cup. I don't have a manual, so could some one tell me what sprocket combinations I would use to run either the low rate or regular rate. TIA
