GR33AP  Graphic Recorder/Printer

• Digital input version of the GR33A Graphic Recorder

• Ideal for installations in a confined space, requiring only 368 mm (14.5 inches) of depth

The model GR33AP Graphic Recorder/Printer is an innovative, fully programmable instrument for scientific, industrial and commercial applications.  This model is designed to operate under host computer control, while retaining the front panel controls to the recorder features and functions.

When under computer control, the user has complete access to all of the GR33AP's Chart Recorder, Alphanumeric, and Raster Graphics capabilities.  Using or moving from one mode to another is simply a matter of implementing the command set provided.  All of the built-in features of the GR33A are retained with the exception of the analog and other optional inputs.

In the Chart Recorder mode, traces are produced from digital data received from a computer via the serial or parallel ports (both standard).  The host computer can define up to 32 traces, which are printed simultaneously with one of the 22 selectable grids, eliminating any drift between waveforms and grid.  Messages can be simultaneously printed with the traces.  The Alphanumeric mode allows text to be printed as a line printer with various formats being software selectable.  The Raster Graphics mode allows the user to access the 1240 individual printing elements to produce images.

Remote Control

The recorder may be totally controlled remotely from the host computer, and in addition, the host can disable the operator control panel.

Low Maintenance

This extremely reliable and very low maintenance recorder is based on the proven thermal array printing technology which produces a precise graphic record on the large format 321 mm (12.625 inch) wide chart.  The only moving parts are the chart stepping motor, the drive roller, and the paper supply and the internal take-up spool.

PC Compatible Software

The optional PC33 Interface and Control Software is available for those working in the PC environment.  One of the many features of the software is a library of routines for control functions, as well as routines for producing traces on the recorder from digital data.

DISP33 Virtual Chart Recorder Display is an optional program that graphically displays data from the GR33AP Recorder in real-time.  The program uses an IBM-compatible computer to create a display that resembles the output of the chart recorder - vertical traces on a chart.  Traces are drawn in different colours, with matching labels.  Several charts, each with its own gain and zero point, can be displayed on one screen.  Up to four screens can be defined in a single configuration.
