The Hardware Driver Adaptor

The hardware driver adaptor (or just adaptor) is the interface between the data acquisition engine and the hardware driver. The adaptor allows you to:

Pass information from the hardware driver to the engine. In particular, the adaptor informs the engine of any hardware-specific properties. If hardware-specific properties exist, then the properties (and their default values) are incorporated into the engine.
