Figure 5.13 illustrates addressing 4 modules, each with the same I/O group
number, but in the four different racks of a single I/O chassis.

Important: When addressing a block transfer module, it must be
addressed by the lowest group number that it occupies and at slot 0. For
example: a 1-slot block transfer module in rack 1, groups 2 and 3 (slot 2)
would be addressed (by rack-group-slot) at location 120. Be aware that
this module is occupying group 2, slots 0 and 1, and group 3, slots 0 and 1.
