Data Display and Analysis from Java

The NetAcquire Java interface offers an easy and efficient cross-platform approach to distributed data acquisition, display, and control. Both standalone Java applications and browser-enabled Java applets can connect to NetAcquire hardware to obtain real-world interfaces to analog, digital, and serial data.

The NetAcquire Java Toolkit includes support for JavaBeans, which allows interactive screen development without programming. JavaBeans are pre-engineered Java components that can be graphically configured. The NetAcquire Java Toolkit includes JavaBeans components are included for graphing, text and lamp displays, tables, disk logging, scaling, real-time network communication, and data distribution. These components allow the creation of real-time data display screens and virtual instrument front-panels in only minutes.

The Java class files for completed applets can be uploaded to the NetAcquire server's integrated Web server, making the applet immediately available across the enterprise.

Also included are sample programs that illustrate advanced real-time displays, including continuous data charting.
