Hardware Configuration and Installation
Do not change the logical address of the VXI-MXI unless you are connecting multiple
VXI-MXIs to the MXIbus. In this case, refer to the VXI-MXI User Manual that came with
your additional VXI-MXIs for more information. You can change the logical address of the
VXI-MXI by changing the setting of the 8-bit DIP switch labeled LOGICAL ADDRESS SWITCH
on the front panel. The ON position on 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 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.
Figure 2-6 shows switch settings for logical address hex 1 and C0.
