 Now wire the Create Channel.VI's task out pin to the Read.VI’s task in pin, and the Create Channel.VI’s error out pin to the Read.VI’s error in pin.  It should look like this: Now wire the Create Channel.VI's task out pin to the Read.VI’s task in pin, and the Create Channel.VI’s error out pin to the Read.VI’s error in pin.  It should look like this:

 Next, we will add a simple way to display the value read from the USB-1608G.  Hover your mouse over the Read.VI, move the mouse so it is over the data pin.  Use the Context Help to help you locate it if needed.  When the cursor is over the data pin, it will change from an arrow to the wiring tool.  When this happens, right click and select Create >> Indicator.  Your Block diagram will look like this: Next, we will add a simple way to display the value read from the USB-1608G.  Hover your mouse over the Read.VI, move the mouse so it is over the data pin.  Use the Context Help to help you locate it if needed.  When the cursor is over the data pin, it will change from an arrow to the wiring tool.  When this happens, right click and select Create >> Indicator.  Your Block diagram will look like this:

 The next step is to tell the Create Channel.VI what physical channel of the USB-1608G to measure. Hover your mouse’s cursor over the Create Channel.VI, then move it over the Physical Channel pin, when the cursor changes to the wiring tool, right click on the pin, and select Create >> Control.  Your Block Diagram should look like this: The next step is to tell the Create Channel.VI what physical channel of the USB-1608G to measure.
