VXIpc-486 Model 500 Series
CLK10 Generation
W24 configures the receiving source for the CLK10 reference. For internal clock generation,
leave the jumper in the default position as shown in Figure 2-4a. When the source is from the
CLK10 SMB connector on the front panel of the VXIpc-486, set the jumper as shown in
Figure 2-4b. Notice that when configured for Non-Slot 0, CLK10 will always be received from
the backplane.

VXIbus CLK10
This jumper block configures the CLK10 transceivers. Figure 2-5(a) shows the default Slot 0
configuration in which the VXIpc-486 sources the CLK10 signal. If you want to configure the
VXIpc-486 as a Non-Slot 0 device, you should choose the setting in Figure 2-5(b). In this
configuration, the VXIpc-486 does not drive the CLK10 signal onto the bus.
Warning:
Do not set the W32, W33, W35, W36 jumper block to any setting other than those
shown in Figure 2-5. Any other settings could result in damage to the VXIpc-486
and any other devices installed on the backplane.
