Hello, and thank you for your reply.
I'll try to describe it in detail.
I have a PXI with two cards pxi-6115 and pxi-2514.
Using pxi-6115 digital output I've generated a set of two impulses, and first one triggers pfi0 of pxi-6115 and through it aquisition of AI0.
I wanted the signal on pfi0 of pxi-6115 to trigger pxi-2514 at the same time to close the relay (channels ch0 and dut0) and the second impulse (which does nothing to AI0 aquisition) to open the relay (disconnect ch0 and dut0). As I've mentioned this digital signal is connected to pfi0 of pxi-6115.
I tried to route that signal to pxi-2514 ttl0, but with no luck.
I attach png files with my test solutions.
Best regards
