I have a PCI-6221, and when I try to enable the digital filter on it, I get an error message indicating that digital filtering is not supported. According to the spec sheet for the 6221, it does support digital filtering on the DIO lines. How can I get digital filtering to work with this board.
Here is the code that I used to try to enable filtering:
/// <summary>
/// Initializes a new instance of the LaserFootswitchMonitor class.
/// </summary>
/// <param name="digitalInLineToMonitor">The digital input line on which the footswitch is monitored.</param>
/// <param name="monitorInterval">The interval, in milliseconds, to monitor the footswitch.</param>
public LaserFootswitchMonitor(string digitalInLineToMonitor)
