I am trying to trigger my cDAQ-9178 on the chassis PFI0 line. My digital input, unfortunately, is not 0-3.3V, but rather the low state is at 1.6V and the high state is near 5V. Using this trigger source, the cDAQ does not register the trigger at all. I'm assuming I need a pull down resistor to bring intermediate level to low. I'm wondering if there is a way to this programmatically on the board itself, rather than using an external resistor. I know some devices have this option, but I'm not sure how I would do this on this device.
