Figure 3-2.  Logical Address Selection
VXIbus Slot 0/Non-Slot 0
The VXI-MXI-2 is configured at the factory to automatically detect if it is 
installed in Slot 0 of a VXIbus mainframe. With automatic Slot 0 detection, 
you can install the VXI-MXI-2 into any VXIbus slot.
You can manually configure the VXI-MXI-2 for either Slot 0 or 
Non-Slot 0 operation by defeating the automatic-detection circuitry. Use 
the three-position jumper W2 to select automatic Slot 0 detection, Slot 0, 
or Non-Slot 0 operation. Figure 3-3 shows these three settings.
Caution
Do not install a device configured for Slot 0 into another slot without first 
reconfiguring it to either Non-Slot 0 or automatic configuration. Neglecting to do this 
could damage the device, the VXIbus backplane, or both.
