synchronize digital output AND digital input NI-USB 6343

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!!
