Parking Brake example in FS2Phidgets4

I'm hoping tht someone would be kind enough to post a brief example of a Parking Brake function within FS2Phidgets. I can't seem to get this simple action to show up in FSX. I have confirmed that FS2Phidgets and the Phidget 8/8/8 card is communicating correctly with FSX, due to the fact that I can see an Analog Input Throttle_Lever_1 movement function correctly. It's this simple switch function (Digital Input) that I can't get straight (I'm a newbie to all this).

I can see the physical switch movement show up as an On/OFF, but I think I have the parameters set incorrectly for the "Configure" and the "Manage FS Variables" areas. I would greatly appreciate some clarification on this. Thanks.
