Description

Designed For Remote Applications

The dataTaker DT80M intelligent universal input data logger is a fully featured low-powered logging platform with an integrated cellular modem, making it perfect for remote applications. The rugged design and wide operating temperature range of the DT80M provides reliable operation in virtually any environment.

The DT80M’s perfect balance of performance with ultra low power also allows you to use a smaller solar panel without compromising on functionality.

Communications

Mobile network outages can occur at any time and can last for minutes or days, however dataTaker has gone to great lengths to ensure the reliability of data transmissions. The DT80M can recognize incomplete downloads and will try again until the entire data file is transmitted, ensuring no lost data. If the network drops your logger, the modem automatically reconnects before the next scheduled transmission.

If the mobile network has marginal coverage, the DT80M can scan for alternative networks and select the strongest signal.

Automatic Data Delivery

Forget traveling long distances to get your data. Utilize the DT80M’s automatic data delivery features to schedule your data to be automatically emailed to your inbox every day, week, month or other time interval. More sophisticated systems can make use of the automatic data delivery features to send logged data to an FTP server. Alarm conditions can also  trigger data delivery in addition to sending alarm messages to multiple email addresses or mobile phones.

Easy To Configure

The DT80M is configured directly in your web browser using dataTaker’s dEX graphical interface. dEX takes you through the configuration of your logger, showing you wiring diagrams and allowing you to decide – in as much or as little detail – how you want to the system to work, suiting both novice or advanced users. Using the internal modem you can even  re-configure your system remotely over the internet if required.

Software

dEX Software

dEX is an intuitive graphical interface that allows you to configure your data logger, view real-time data in mimics,
trend charts or tables and retrieve your historical data for
analysis.

dEX comes pre-installed on every logger in the DT80 range. The software loads in your web browser so there is no need to install cumbersome applications on your computer. Being browser-based, dEX will work on all major operating systems including Windows, Mac and Linux.

Configuration Editor

dataTaker dEX Configuration EditorThe configuration editor allows you to view, edit and save logger configurations in an easy-to-use Windows Explorer style user interface. The configuration tree view allows definition of measurement schedules and measurements.

Wiring diagrams show available wiring configurations for each sensor type. Configuration can be stored and retrieved on either the logger or a local computer.

Mimics and Charts

dataTaker dEX Mimics and ChartsMimics are organized into panels which can be modified to highlight custom alarm conditions or data grouping. Mimics include dials, bar graphs, thermometers, etc. Real-time chart recorder mimic allows you to view trends and historical data over a custom time/date range. Up to 16 mimics can be displayed on up to 5 mimic pages.
