Device Properties

Device properties are stored in the system and read by the driver when it loads, and then the device is programmed according to these loaded values. The properties are protected during read and write access times, and some of them are pre-defined by the configuration dialog box. Different device's functions are influenced by different properties. These properties are represented by an ID code for an application that calls Advantech API functions. An application can use a default value set by the configuration dialog box, or call Advantech API functions: DRV_DeviceGetProperty and DRV_DeviceSetProperty, to modify individual properties in running time.
