Planning a VXIbus/MXIbus System Logical
Address Map
The VXIbus/MXIbus system integrator is the person who configures all
the VXIbus and MXIbus devices and connects the system together.
This chapter assumes that you are the system integrator.
Before you begin setting the logical addresses of the devices in your
VXIbus/MXIbus system, you must determine the tree configuration of
your system. The two basic configurations are the MXIbus multiframe
RM as an external PC with a MXIbus interface, as shown in Figure 6-1,
or the MXIbus multiframe RM in a VXIbus mainframe, as shown in
Figure 6-2. The location of the multiframe RM constitutes the root of
the system tree. MXIbus links connected to the root of the tree form
levels of the tree. Notice that only one MXIbus link can be connected
on the first level below a root PC multiframe RM, while multiple
MXIbus links can be connected on the first level below a root VXIbus
mainframe.
