Issue Details

I have a USB cDAQ chassis and I would like to implement a watchdog (for example I need a pin to keep the high state when the USB cable is unplugged), can I do it? 


The DAQmx driver has Watchdog functions but you can use those only with cDAQ 9185/89 or the 9188XT which are not USB but Ethernet versions, so it's not possible to do it with a USB cDAQ chassis.
