Export Marker Event on PXI Trigger Line

[jstarustka]

I am trying to create and export a marker event using the RFSG or the PXI-5610 and 5441 combo onto the PXI trigger line.  After reading the Advanced sequencing file on the web site it said that this is possible.  I also used the shipping example Marker Events.vi as a basis for my own vi.

Basically using my VI and exporting it onto the PXI Trigger Line I get nothing but when I use the PFI line it exports fine.  I really need to use the PXI Trigger Line due to not having the 9 pin circular DIN cable needed to connect my PFI0 output to the PXI-5142 OSP Digitizer Card I am using.  Attached are screenshots of my TX and RX vi and show how I am generating the marker event and trying to export it.  Any help that will let me know why this is not working would be greatly appreciated.

Thanks

Hi jstarustka,

Both your Tx and Rx seems fine and even more, when you have it working on a PFI line and not a RSTI (or PXI_Trig) line it might be due to other problems. Have you reserved the trigger lines if you have a multisegment chassis (more than 8 slots)? You have a great knowledge base here:

Routing PXI Trigger Lines Across the Buses of Multisegment PXI Chassis

This should work unless there might be a problem with the RTSI line you are using, make sure you try a couple of them. Finally, just to confirm, I would use two shipped examples to make sure this is not the code:

For the acquisition side use the shipped example called "niScope EX Configured Acquisition.vi"
For the generation side use the shipped example called "niFgen_Arb_Waveform_Marker_Example.vi"

Hope this helps,
