New Project Config

Just getting started with a new project. Already designed using lots of cardboard (courtesy the Walmart I work at - the electronics department especially for their TV boxes). Haven't even ordered the EPIC card yet and I already have a question. Is there any maximum to how many EMDA cards can be daisy chained together? After figuring out all the switches and buttons I'll need, seems to be around 127 altogether (B737-800 full mock-up).Hoping to have somebody at least try to poke holes in my plan.Light Heirarchy of BoardsEPIC USB -> Expansion module -> 32pt Output -> EMDA v2 (Light Side) #1 -> #2 -> #3 -> #4 -> EMDA Pro-34 #1 -> #2 -> #3 -> #4Switch Heirarchy of BoardsEPIC USB Bus Connection -> EMDA v2 (Switch Side) #1 -> #2 -> #3 -> #4That should take care of all the switches and lamps. Another consideration is the rotary encoder card for my 20 rotaries. I think that has to plug into the EPIC Bus, but not sure on that.Another issue I'm trying to figure out is the module/row positions of each card. General config would be:EPIC USBRotary Module EPIC BusEMDA #1 EPIC BusEMDA #2 EPIC BusEMDA #3 EPIC BusEMDA #4 EPIC BusEPIC USBExpansion ModuleEMDA #1 Expansion BusEMDA #2 Expansion BusEMDA #3 Expansion BusEMDA #4 Expansion BusEMDA Pro-34 #1 Expansion BusEMDA Pro-34 #2 Expansion BusEMDA Pro-34 #3 Expansion BusEMDA Pro-34 #4 Expansion BusTotal cards:EPIC USBExpansion ModuleRotary Module4x EMDA v24x EMDA Pro-34Again, thanks for reading this far.
