Alternative Worksheets for Planning Your
VXIbus/MXIbus Logical Address Map
For most VXIbus/MXIbus systems, you may find the following
worksheet helpful when setting up a system using the High/Low format
for window configuration. The entire system can be described on one
worksheet. Remember that the High/Low format cannot be used with a
standard VXIbus Resource Manager.
The dotted lines can be used to add additional MXIbus links to Level 1
of the system, or to connect a Level 2 MXIbus link to one of the
devices on Level 1.
Figure 6-16 presents one of these worksheets filled out for the example
VXIbus/MXIbus system shown in Figure 6-5. Notice that the system
does not take up as much of the logical address space as the Base/Size
method of configuration because address requirements do not have to
occupy blocks in powers of two. With High/Low configuration, you
can configure each VXI-MXI-2 window for exactly the amount of
address space the mainframe needs.
Figure 6-17 is an alternative logical address map worksheet for you to
fill out for your VXIbus/MXIbus system.
