Implement watch dog for USB-6251

[ediorz]

Hi,

I am pretty new to NI DAQmx and USB 6251 so I might be asking a question that has a obvious answer here....(also if I should post this question somewhere else please let me know)

I am trying to implement a watch dog timer that will trigger a digital output (static or waveform) to a signal light

From the spec for USB 6251, I can see that it does not have a built in watch dog timer that I can use..

Therefore, is it possible to implement my own watch dog timer (hardware timer not software)using the hardware spec for this device??

I am programming using C# .NET 4.0 which i can see the methods for watch dog but cannot use due to hardware spec..

Maybe my best thing to do is buy a model that supports watchdog??

Thanks in advance,

Edward

I should add more information for this...

So what I am trying to do is as follows:

1) have a watch dog timer that is configured to turn on a warning light when expired

2) have the software side to keep up resetting the time so it will not expire

3) when software crashes or anything events that stops the setup, the watch dog will trigger ths warning light (i.e. set the signal for digital out)

so is the above doable for USB 6251???

Thanks,
