How to set debounce filter time

[nantek]

Could anyone tell me how to set the debounce filter for the digital input Port 1/ Port 2 of the NI 6259 using LabWindows/CVI 8.1.1?  According to the specification sheet, the choices are 125ns, 6.425us, 2.56ms, and disable, but I couldn't find what function to call to select these options.

TIA

Hi nantek,

You will need to set the Digital Filter Enable to true.  You must also configure the Digital Filter Minimum Pulse Width attribute/property. This value represents the minimum value that is guaranteed to pass into the TIO. The minimum pulse width guaranteed to be blocked is one-half of the Digital Filter Minimum Pulse Width attribute/property.

This is discussed in the knowledge base article, Enabling the Digital Filters for Counter/Timer Devices in NI-DAQmx.
