Telemetry Device with 3G + 2G Cellular / Satellite communication and Programmable Logic


How does it work?

The GRD family of products helps control and supervise any kind of equipment from distance, be it a control system or process system facilitating the implementation of the remote telemetry systems.

The GRD family of products helps control and supervise any kind of equipment from distance, be it a control system or process system facilitating the implementation of the remote telemetry systems. Additionally it includes the possibility to load a text script to perform internal logics.

    Internal Logic Programming:

    What is a Script?
    A Script is a file with orders that once loaded on to the GRD1300, or GRD3305, is interpreted and executed.

    Operations performed by a Script: The Script describes what operations should be executed by the device, for example:

  • Math Operations
  • Binary Logic Operations
  • Date and Time Operations
  • Working with Timers
  • Read Analog variables
  • Records of Variables
  • Digital I/O Read/Write
  • Sending and receiving SMS
  • Interpretation of data from the serial port

  • Telemetry Web Server

    It is a powerful computer with Internet access, dedicated exclusively to hosting Cellular Telemetry Applications.

    How it works?
    With this new server, you can implement immediately, all applications of cellular telemetry using pre-designed web pages. Just connect sensors to the Exemys GRD Devices, and configure your application in minutes.
