VXIbus Local Bus Configuration
VXIbus CLK10 Routing
When the VXI-MXI-2 is installed in Slot 0 of your mainframe, it supplies
the VXIbus CLK10 signal. The VXI-MXI-2 can use three different sources
to generate this signal: an onboard oscillator, the external CLK SMB
connector, and the MXIbus CLK10 signal. Use the three-position jumper
W3 to select these options, as shown in Figure 3-5.
Notice that Figure 3-5b and Figure 3-5c also show switches S3 and S7,
respectively. You must configure these switches as shown when using the
corresponding CLK10 source setting of W3.
