Counter change to high when quitting LabVIEW

Hi,
I am using the GPCTR0_OUT output on my PCI-6052E board as a watchdog output. I need this output to be low while my application is running and high otherwise. However I have found that the output switches back to low as soon as I quit LabVIEW. How can I avoid this behavior?
Thanks!

You can apply pull-up resistors to the counter outputs to force their default state to be low or high (depending on your requirements). Take a look at the following KnowledgeBase article (Default State of Counter Output Lines on E Series Data Acquisition Devices). At the bottom, there is a link to another KB that describes how you can change the default power-up state of the DIO lines, and this also applies to the counters.
