I have a PXIe-1075 and a PXIe-1082, and need to access (via SMBus) the PXI Trigger routing controller (or PXI trigger bridges) to bus all PXI_TRIG signals across the complete backplane, and so across all segments. I don't have access to Labview on the used System Slot computer, and have to use Linux. I think the SMBus device can be accessed at address 0x5A (Clocking CPLD), but I'm not sure. Can you provide a register description of the PXI Trigger rounting controller or PXI trigger bridge? Or could you describe which codes should be written to which registers to have all PXI_TRIG lines bussed across all segments?

PXI

Thank you for the information.

I succeeded PXI Routing using NI VISA C API.

Please note that you can't install NI driver on RT kernel. I used generic kernel.
