To create a binding between a switch and a controller, the controller is first put in an Allow Bind mode.
This is followed by issuing a Bind request on the switch (within the timeout period). This will create a
binding from the switch to the controller.
A switch can be bound to more than one controller by repeating the above process.
To reassign the bindings for a switch, the Bind request is issued with a delete parameter. This will remove
all bindings for that switch. It can now be bound to other controllers by following above procedure.
