synchronize digital output AND digital input NI-USB 6343

[nkhoa]

Hello

I'm using NI-USB 6343 to drive 1 TTL device. This device can also output a TTL signal to indicate whether the gate is opened/closed. 

I'm using Digital Bool 1 Line 1 Point. I was able to flip gate open/close in timely manner. But i Like to sync DI and DO properly.

I tried to throw in OnBoard clock but it was not successful. 

Is there any way to sync DI and DOI using onbaord/hardware clock?

Any insight will be great!

Thanks!!

Hi,

Synchronizing your DI and DO tasks should be possible with your device. You will need to time them off of a a clock that is usable by both. This information is available in the X Series User Manual

https://www.ni.com/docs/en-US/bundle/pcie-pxie-usb-63xx-features/resource/370784k.pdf
pg 6-9 and 6-13

You can also find some information and examples of syncing various tasks in the article below.

Best of luck,
