Digital Signal lasting specific chosen time

[violetaaraque]

I'm trying to generate a digital signal with my USB-6008 to talk to another instrument. I'm not able to do any hardware timing using the DAQmx Timing VI, so how do I send a signal with specific timing?

You cannot do hardware timing with your cheap (and old) USB6008 - read the specs carefully!

When you want to specify timing in the low ms range (5-10 ms) you could use a loop with a wait function…

Otherwise look for better DAQ devices with hardware-timed DIO pins!

Which instrument? Which protocol?

What is the other instrument?  What is the protocol of the signal you are trying to send to it?  Anything modern instrument using TTL level signals will be using RS-422, SPI, or I2C.  There are dedicated hardware to handle these protocols that will make your life A LOT easier.
