E1406-3 : Set the Clock Source
Set the clock to one of the following:
• Internal - to use the Command Module’s 10 MHz internal clock,
CLK10 (factory default), or
• External - to use the clock supplied at the SMB faceplate connector
on the Command Module.
The clock is distributed to every slot along the VXIbus backplane.
Disabling the slot 0 and (VME) System Controller functions removes the
internal clock or external clock from the VXIbus backplane. However, the
clock from either source is still present at the ’Clk Out’ SMB connector.
See Appendix A, "Terms and Definitions," for more information about the
Command Module CLK10.
