GL-Connection Software Ver.2.20 - integrated with the GL series

Software for high performance and easy operation
Allows connections of Graphtec's midiLOGGER series

The GL-Connection software included with GL7000, GL2000 and GL980 can control devices. It is an integrated application software for the GL series, the GL900, GL840, GL820, GL240 and GL220 can also be connected and controlled.

Various measurement screens

The measurement signal can be displayed in various types of screens adapted to applications.

Multi-window function, measured signal can be displayed in various forms

Multi-window function

The GL-Connection software supports up to 2000 channels and up to 20 units of the GL series. It splits up to 4 windows and each window can display different format for easy monitoring signal in large channels.

When the unit of GL series is connected to the PC via Ethernet or USB, the GL-Connection software can manage a various information such as the data in capturing, data in the free running - displaying data without saving - and data in saved file. The GL-Connection software can also display the data saved on the PC.

Tab function

The tab function allows you to manage the screen so that it can be intuitive and easy monitoring. Screen displayed in multi-window can split using the tab and selected items can be displayed. Items to be displayed can be set in detail, such as the GL body level, individual input module level, the specified channel, and other settings.

When controlling GL7000 from PC, it is impossible to operate on the main unit to prevent conflict of setting conditions.
It allows to operate the main unit even when GL7000 is under controlling from PC.

Integrated application software for the GL series

GL-Connection software is an integrated application software for GL series including GL7000, GL2000, GL980, GL900, GL840, GL820, GL240, and GL220. When the software is used with the GL7000, it can be controlled and displayed the data including the FFT measurement. When other GL series is used, the software has mainly the waveform viewing function and have also the function to control basic items. Data captured by other GL series is compatible with the GL-Connection and APS software.

Connection of multiple units and the integrating function of the saved data

GL-connection software will be able to manage multiple units in a mixed condition of the GL series. Data integration function allows you to understand the overall situation immediately by creating single file at the same time axis from multiple data file saved by each unit.

* Full synchronization can be made when the sync cable is used in the GL7000.

Work flow of data integration

 

(*1)
The integrated file cannot be created when it exceeds 100 units or 100 channels (analog channel + logic channel).
(*2)
Data will be integrated with using fastest sampling speed when the sampling speed in each file is different.
(*3)
The data format in integrated data file is the GL7000 format even if GL series is included to capture the data.

Sampling Limits

High speed sampling is limited by the number of recording channels, connected modules, and the recording destination, etc. Even within the following limits, transmission may be incomplete due to transmission delays with multiple module connections, especially with LAN connections. If this occurs, please reduce the sampling rate. For more details on the GL device limits, please refer to the main module user’s manual on CD-ROM.

Check-sum function It is a function to check data file consistency. The check-sum code is recorded into the file when data file is created by the GL unit. When the content of the file is changed by someone, the check-sum generated from the file does not match with the recorded check-sum, which indicates that the file has been tampered with.
* This software and the firmware on the GL unit need to be a version that supporting the check-sum function.
File operation Converts binary data to the CSV data (specific period, all data in one file, multiple files), Creates a new file with compression or by consolidating multiple files.
