PXI 6555 Singal Routing

[Bai_AT_80]

Hi

I want to generate a singal via PXI 6555, and make this singal as the external trigger source of another card in a same PXI chassis. So I want to route this singal through PXI trigger line. I can route singal from PFI0 to PXITrig0 using function "niHSDIO_ExportSignal", but my generated singal is on channel DIO0, how can I do the route? Thanks.

Hi Bai,

After refering to the spec of 6555, I think you can use DIO <0..23>, PFI 1, PFI 2, PFI 4, and PFI 5 for generation.

As described in the document below, DIO cannot be routed internally to pxi_trigger line.

Destinations →	Front Panel				Backplane			Internal
Sources ↓	CLK OUT	PFI 0	PFI <1..3>, PFI <24..31>	DDC CLK OUT/PFI 4	PXI_TRIG <0..7>	PXI_TRIG <7>	PXIe_DSTARC	Start Trigger (Gen)	Pause Trigger (Gen)	Script Trigger (Gen)	Stop Trigger (Gen)	Start Trigger (Acq)	Advance Trigger (Acq)	Ref Trigger (Acq)	Pause Trigger (Acq)
Front Panel
CLK IN	√	—	—	√	—	—	—	—	—	—	—	—	—	—	—
PFI 0	—	—	√	—	√	—	√	√	√	√	√	√	√	√	√
PFI <1..5>, PFI <24..31>	—	√	√	—	√	—	√	√	√	√	√	√	√	√	√

So I think you should use PFI 1, PFI 2, PFI 4, and PFI 5 for your purpose and route them to pxi trigger line.

How can I generate singal use PFI1, is there a demo?
