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.
