The VXI-MXI-2 can also be configured to drive the external CLK SMB
signal from the VXIbus CLK10 signal. Switch S3 controls whether the
VXI-MXI-2 drives or receives the external CLK SMB signal. If you change
the S3 setting to drive CLK10 out the external CLK10 SMB connector, do
not set the W3 jumper to receive the SMB CLK10 signal; instead use the
settings shown in either Figure 3-5a or Figure 3-5c as appropriate.
When switch S3 is set so that the VXI-MXI-2 receives the SMB CLK10
signal, you have the option to add a 50 is unused—its setting does not
matter—when S3 is configured to drive the external CLK SMB signal.
