Height Method: External Height [PickMaster 5]

Has anyone used the External Height Method in a Patmax Model? I have a system where an Item is coming down the conveyor, but the height can vary from production run to run. I want to write the height to the PickMaster PC and then have the camera compensate for the differing height.

Additionally, when I select this method, the Model Height data entry field gets grayed out. At what height do I teach my model at?

Attached is the draft of the documentation to this function.
