present on the bus.
A typical scenario involves more than one USB equipped SCADAPack controller connected
via a USB hub to the host PC.
If multiple controllers exist on the bus, the controller ID drop down box will display a list of all
identifiable devices. The user connects to the controller in question by selecting its Controller
ID from the list. The Controller ID takes on the format „A123456‟ and can be found printed
on the controller casing or the circuit board.
