Instrument drivers are software applications that control scientific instruments, allowing configuration and remote control. Manufacturers and independent companies make drivers, and researchers can create their own. Drivers provide a familiar environment for operators to configure, command, and log data. Interchangeable virtual instrument drivers (IVI) are highly configurable and useful for developing new instruments. Automation is possible with drivers, but calibration is important. Replacement drivers are available from manufacturers’ websites or directly from the manufacturer. Many instrument classes can be controlled through drivers, and manufacturers can provide recommendations and advice.
An instrument driver is a software application that can control a scientific instrument. These drivers enable configuration and remote control of instruments, including instruments still in development and testing that may not yet have reliable control systems. Instrument manufacturers make drivers that they package with their products, and independent companies also make drivers for a variety of applications. Researchers can create their own if they are familiar with programming languages and have very specific needs.
The instrument driver creates a familiar and easily controlled environment for the operator. He or she can configure the instrument and adjust settings, command it to perform specific operations, and log data via the driver. The level of control and complexity available can depend on the driver and operator skills. Drivers can handle input in many programming languages, and many are highly configurable.
Some use a protocol known as an interchangeable virtual instrument driver (IVI). These drivers have tremendous ability to control and change. Researchers and developers use this type of instrument driver in developing new instruments and refining controls. Even scientists working on the bench on specific projects can use this type of instrument driver if they want more flexibility and control with a project.
Instrument drivers can allow operators to engage in very detailed and complex tasks. One benefit of drivers is the ability to automate. The operator can set up tools to perform particular functions at specific times or in response to triggering events. Automation can increase reliability and repeatability, as long as the tools are calibrated correctly and do what they are supposed to do in response to the driver. Errors in the function can lead to false or incomplete results.
Replacement drivers for many scientific instruments are available on manufacturers’ websites. It’s also possible to order them directly from the manufacturer if they’re not online, which might be the case with older drivers or manufacturers that don’t have a significant web presence. In the installation process, the instrument driver may perform a series of settings and test operations. It is important that the user pay attention to the messages on the screen and follow the instructions carefully for safety and correct calibration.
A number of instrument classes can be controlled through the use of an instrument driver. If a researcher is not sure whether a laboratory piece of equipment can be controlled remotely, he can contact the manufacturer for information. The manufacturer can provide specific recommendations and advice and may have a compatible driver available.
