W800RF32 and DS10A

I wish to use several DS10A units with a W800RF32. If the DS10A units generate their own codes [not set by code wheels] then I assume the W800RF32 simply receives and passes these code on to the computer and at this point software must interpret the code[s]. Does a extensive if- then table of every code combination have to be set up in the software to archive automation based on the code[s] received? Secondly, if you change the DS10A batteries does the unit generates another random code for itself? TIA.... Mug
