I assume the 9911 can learn the signals from the original remotes.

If the signals are simple enough and/or few enough that they all fit in the 9911's eeprom, then you don't need a setup code, and upgrade from OFA, a JP1 cable or anything else.

More likely they don't all fit. Then a JP1 cable is the best answer. With it you can read the learned signals and decode them and convert them into device upgrades that will fit.
