synchronize analog output input and triggered digital output

[garcijon]

Hi All,

Im trying to collect analog data, generate an outgoing clock + trigger using an NI USB 6289 multi function DAQ. 

The analog data needs to be sampled at 5kHz but needs to sync with an external device at 1kHz. I wrote the vi such that the analog output would create a square pulse of 1kHz.

I thought that if I synched the analog input/output then the analog clock I'm outputting would be synched to the external device. 

I tried to add a trigger for the external device to start which should be synched to my analog input/output but when I try to send a digital pulse I get no output and there is no error.

Hi garcijon,

What external device are you using? Additionally, you are not properly writing your digital data. You can find an example at Help»Find Examples...»Browse»Hardware Input and Output»Digital Output»Digital - Continuous Output.vi

Thanks,

I will review the example. The external device would be a DAQ on another pc which controls a motor and collects sensor data from it.
