PXI-2514 triggering with TTL signal

Hello,

 

I'm looking for help regarding opening and closing of the individual relay on PXI-2514 card through use of TTL signal.

I'll appreciate any help.

 

And, as this is my first post - hello everyone, I'm glad to be here 🙂

Hi M_Corto,

 

Where is the source of the trigger?

Please describe in more details what you are trying to achieve.



Essentially, you can find more details about triggering and behavior of this device at this link:

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.
