A data acquisition system comprising a Configuration Manager for intelligently managing access to DAQ configuration information. The data acquisition system comprises a computer system coupled to a data acquisition device, a data acquisition application (user application) executing on the computer system, and DAQ driver level software executing on the computer system. The memory of the computer system stores a hardware database which includes information on DAQ objects in the DAQ system, and the memory stores configuration files which comprise desired configurations of the DAQ system. The Configuration Manager of the present invention executes in the computer system to control access to the hardware database and configuration files stored in the computer system. The present invention also includes a method for providing access to information on data acquisition (DAQ) objects in the DAQ system. The Configuration Manager accesses the configuration information from the system memory if the configuration information comprises modified parameter values stored in the memory, and the Configuration Manager otherwise accesses the configuration information from the hardware database. The present invention also includes a method for providing access to additional or new information on data acquisition (DAQ) objects in a DAQ system. The user of the DAQ system can receive an updated hardware database, and an existing configuration file can automatically access the additional capabilities of the DAQ object from the installed updated hardware database.
