Hi, this is my first program in labview. I want to use a while loop to continuously input data to the DAQ , which displays it to an oscilloscope. The signal out should be controlled by a switch (0 when switch is open and 1 when switch is pressed). I placed a toggle switch in the while loop, and connected the output to the DAQ manager, but it is showing a connection error. Type of source is boolean. Type of sink is 64 bit real. So how should I convert data from the switch so that it gets fed into the DAQ output? Thanks.

Also while you configure the Digital output you should select single channel instead of multiple (unless you really have multiple channels) then you will be able to wire the switch directly to it.
