VXI-MXI-2/B Configuration and Installation
VXIbus Slot 0/Non-Slot 0
MXI-2 Configuration Reference Manual
You can change the logical address of the VXI-MXI-2/B by changing
the setting of the 8-bit DIP switch at location designator U20 (refer to
Figure 6-1). The ON position of the DIP switch corresponds to a logic
value of 0, and the OFF position corresponds to a logic value of 1. Verify
that the VXI-MXI-2/B does not have the same logical address as any other
statically configured VXIbus device in your system. Remember that logical
addresses hex 0 and FF are not allowed for the VXI-MXI-2/B. Also, when
setting logical addresses, keep in mind the grouping requirements set by the
system hierarchy. Refer to VXI-6, VXIbus Mainframe Extender
Specification, for more information on setting logical addresses on a
multichassis hierarchy.
Figure 6-2 shows switch settings for logical addresses hex 1 and C0.
a. Switch Set to Logical Address 1 (Default)
b. Switch Set to Logical Address Hex C0
Figure 6-2. Logical Address Selection
The VXI-MXI-2/B is configured at the factory to automatically detect if it
is installed in Slot 0 of a VXIbus chassis. With automatic Slot 0 detection,
you can install the VXI-MXI-2/B into any VXIbus slot.
You can manually configure the VXI-MXI-2/B for either Slot 0 or
Non-Slot 0 operation by defeating the automatic-detection circuitry. Use
the three-position jumper W3 to select automatic Slot 0 detection, Slot 0,
or Non-Slot 0 operation. Figure 6-3 shows these three settings.
