Trigger Input Termination; Figure 3-18. Trigger Input Termination Option Settings - National Instruments VXI-MXI User Manual

Configuration and Installation
The VXI-MXI must be installed in Slot 0 if you want to route the INTX CLK10 signal to the
VXIbus CLK10 signal. The CLK10 Source Select jumpers on the VXI-MXI must be set to
configure the VXI-MXI to receive the CLK10 because the INTX daughter card will now be
sourcing the clock signal. You can configure the VXI-MXI to be installed in any slot when the
INTX CLK10 Routing switches are enabled to map the VXIbus CLK10 signal to the INTX
connector.
Warning: Configuring more than one VXIbus device to drive the CLK10 lines or
configuring both the VXI-MXI and the INTX daughter card to drive CLK10
can damage the VXIbus backplane, the CLK10 drivers on the VXIbus devices,
or both.

Trigger Input Termination

The Trigger Input SMB connector can be terminated to 50 ohms by changing the position of
slide switch S5. See Figure 3-18.
