Your VXI-MIO Series module does not support dynamic configuration
of its logical address.
Ensure that no other statically configurable VXIbus modules have the
same logical address as the VXI-MIO Series module. If they do, change
the logical address setting of either the VXI-MIO Series module or the
other module so that every module in the system has a different
associated logical address.
To change the logical address of the VXI-MIO Series modules, modify
the setting of the 8-bit DIP switch labeled LOGICAL ADDRESS
SWITCH (U3 for the VXI-MIO-64E-1 and U73 for the
VXI-MIO-64XE-10). The down position of the DIP switch corresponds
to a logic value of 0 and the up position corresponds to a logic value
of 1.
See Figures 2-1 and 2-2 for the VXI-MIO Series parts locator diagrams.
