Data Display and Analysis from Java

The NetAcquire Java interface offers an easy and efficient cross-platform approach to distributed data acquisition 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 without programming.  The NetAcquire Java Toolkit includes JavaBeans components 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. JavaBeans technology allows icon-based application design from environments like WebGain Visual Cafe™ (screen shot).

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

The NetAcquire Java interface is a package of Java classes that provide communications with one or more NetAcquire nodes. These classes handle all the low-level details of network input/output, flow control, and error handling. Complete distributed NetAcquire applications can be created with just a few lines of Java code. Also included are sample programs that illustrate advanced real-time displays, including continuous data charting.

The NetAcquire Java Toolkit is integrated with NetAcquire Publish/Subscribe and NetAcquire Decommutation, which allows for easy processing and display of telemetry data. These components allow the creation of real-time telemetry data display screens and virtual instrument front-panels in only minutes with little or no programming. Each telemetry measurement is assigned a name that can be referenced from display classes such as graph, text field, table, and indicator light.
