Dimmer Rack Setup

Hello again guys. I have another question about setup. I have a Strand C21 Dimmer Rack system. I'm not sure how I should word this. There are two Racks with 48 dual modules giving me 96 per rack equaling 192 total. How would I fill out the dimmer information on LW6 to correspond with this system? The information available online isn't exactly clear to me so I thought I would stop here and ask.

Thanks everyone!

Jason
