NI 6536 CTR Connection

[Kobi_K]

Hi all ,

I have one of the x-series devices NI-USB 6356 ,

it's working fine but I'm trying to understand it's CTR option , 

my question is what all the CTR 0 connection means ?

I want to create a simple pulse using the CTR and I have 6 connections :

CTR 0 SRC 81 (PFI 😎

CTR 0 GATE 83 (PFI 9)

CTR 0 AUX 85 (PFI 10)

CTR 0 OUT 89 (PFI 12)

CTR 0 A 81 (PFI 😎

CTR 0 Z 83 (PFI 9)

CTR 0 B 85 (PFI 10)

In the hardware level which one is my output ? And what all the SRC , AUX and so on means ?

Hello Kobi,

Thank you for bring this issue to the forums. If you go to the LabVIEW help, and search "Counter Parts in NI-DAQmx," you will find all the information you need.

Please refer to the attachment, Counter Terminals.docx, which will go over the help as well as more information.

For you application, generating a simple pulse, you would find that your pulse would be outputted on the CTR 0 OUT (PFI 12).

Hi Vimal ,

Thank you for the response , I have one more question :

Is it possible to create pulses by time list ?

To set times for the device lets say 0.01 , 0.05 , 0.06 ( sec )

and to get 3 pulses by this time after I've triggered my test.

The idea is to make some pulses with different time scale between each other and to make this time scale as parameter.

Hello Kobi,

Just a clarification, do you want to create a pulse at non-periodic intervals. Like a pulse at 0.01 s, then another at 0.05 s and another at 0.06 s? Also, do you want then to be able to change this on the Front Panel with a control? Or, is this progammatically determined?

Thank you,

It's exactly what you said 🙂

non-periodic intervals with the ability to change the times in my panel before I start my task ,

Thank you

Hello Kobi,

Hope you had a good long weekend. Now, I've found an example which should do everything you want.

You will have to edit this VI to add an output to your USB device.

Thank you,
