Example 4
The flex I/O can also be configured as an input. In this example, two inputs are connected
to a matrix switcher. Using JavaScript, the status of the digital inputs can be checked and
the appropriate message displayed for the user.
Example 4
<br>var ioState1 = ""<br>var ioState2 = ""<br> if ((ioState1 == 1) && (ioState2 == 0)) {<br> document.write('Input #1 Selected')<br> }<br> else if ((ioState1 == 0) && (ioState2 == 1)) {<br> document.write('Input #2 Selected')<br> }<br> else {<br> document.write('No Input Selected')<br> }<br>
Select Input #1
Select Input #2

Using the SSI to assign the state of input 1 and input 2 allows the JavaScript code to
determine which switcher input is selected. This example also demonstrates using a URL
query string in conjunction with the pulse I/O command to allow the user to switch the
matrix switcher with a 250-millisecond closer.
