In the expansion slots, users install the modules, and make
sure of correct installation. Notice that address mapping is order
by slot id of installed module (from left to right), and the
expansion slot that without module will be skipped.

labeled LSB is represented the low nibble of the address, and
the switch labeled MSB is represented the high nibble of the
address. For advance setting, please refer to PROFI-8455
User’s Manual.
