Hardware Needed:

PXI Chassis

PXI Embedded Controller

Software Needed:

LabVIEW 8.0 or newer

NI-VISA

To Begin: Place PXI SMB Trigger Router v2.lvlib in the /Program Files/National Instruments/LabVIEW 8.x/vi.lib folder of your directory. Next, open the SMB Trigger Router v2.lvproj.

Example 1 - SMB Test - AssertionTest.vi

This VI will programmatically probe the PXI Chassis Backplane Trigger lines and the PXI Controller SMB line to determine which are asserted.

Steps for Using:

1. Open SMB Test- AssertionTest.vi

2. Select the value of the Assert Output Control. This VI will set the logic level of the front panel SMB trigger available on PXI controllers.

3. Run the VI

4. Click on the Update Output control to determine which triggers are asserted. The SMB connector on the front panel of the controller and the backplane trigger lines will be programmatically probed.

Example 2 - SMB Test - Routing Test.vi

This VI will route the PXI Controller SMB trigger line to any of the PXI Chassis Backplane Trigger lines. You can also set the polarity of the signal and the direction.

Steps for Using:

1. Open SMB Test - Routing Test.vi

2. Select which trigger line you would like to drive by changing the Trigger control

3. Select the direction of the trigger line

4. Run the VI
