The RM performs the following steps:
1.
Scans logical addresses (0 to FF) and identifies all devices in
VMEbus Mainframe #1. Finds the VME-MXI-2 interfaces at
logical addresses 0 and 1.
2.
Enables the logical address window of the VME-MXI-2 found at
logical address 0 for the entire outward mapping range of 0 to FF.
Scans all logical addresses, skipping all previously encountered
devices, and finds the VME-MXI-2 in VMEbus Mainframe #3, the
VXI-MXI-2 in VXIbus Mainframe #2, MXIbus Device A, and
MXIbus Device B.
3.
Enables the logical address window of the VME-MXI-2 in
VMEbus Mainframe #3 for the entire inward mapping range
of 0 to FF. Scans all logical addresses, skipping all previously
encountered devices, and finds the VME-MXI-2 at logical
address 61.
4.
Enables the logical address window of the VME-MXI-2 found at
logical address 61 for the entire outward mapping range of 0 to FF.
Scans all logical addresses, skipping all previously encountered
