GSM Guard GT1000PRO2 is an upgraded controller for professional installations where stable operation, flexible I/O and mobile communication are crucial.
Version 2 is equipped with faster dual-core CPU, supports OTA-opdatering and is ready for LiveLINK via OTA.
The unit uses CAT-M1 as standard connection and have NB-IoT as backup, which ensures stable and reliable communication – even in installations where network conditions can vary.
GT1000PRO2 has multipurpose inputs, which can be used for ON/OFF, 4–20 mA, Pulse counter up to 40 MHz summit DS18B20 temperature measurement. This makes the device well-suited for monitoring, alarm management, and remote control – especially in the water and wastewater sector, where it is often used with float switches.
In the event of an alarm, a message can be sent via Calls, SMS, or email, while the built-in buzzer can provide a local audible alarm.
LiveLINK is our upcoming communication protocol for professional and industrial solutions where stable operation, reliable communication and future-proof integration are crucial.
Selected products are already prepared for LiveLINK in terms of hardware and software. This means that the units can be configured for the new protocol via OTA update once LiveLINK is fully developed and released.
LiveLINK is designed to form the basis for more uniform and reliable communication across products, installations, and application areas. The goal is to ensure faster reaction times, better monitoring, and more flexible control in future solutions.
When the protocol is ready, compatible devices can be migrated to LiveLINK without the need for physical replacement of the device.
For further information, compatibility, and technical clarification, we recommend, that you contact our support or your nearest dealer.
Our OTA solution (Over-The-Air) Ensure that devices are continuously maintained Up-to-date, stable and operational through controlled software updates.
Firmware and software updates are centralised and deployed directly to devices without the need for physical access. This ensures that devices automatically receive Critical updates, improvements and new features, while maintaining operations.
OTA is developed with a focus on Stability, continuity and professional operation and reduces the need for manual maintenance. The solution contributes to consistent software versioning and high reliability across installations.
OTA is available in several of our latest products.
For further information and technical clarification, we recommend contacting our support or your nearest dealer.
LegacyLINK is our thoroughly tested communication protocol, which has been a central part of the GSMCloud platform since 2020. The protocol has been developed with a focus on Stabilne dryfowanie, simple communication and long lifespan in professional installations.
With LegacyLINK, the device sends a data packet to GSMCloud and subsequently receives a reply back. This form of communication provides a Robust and predictable data exchange, where the unit works stably in the field, while Intelligence, configuration, and management are handled centrally in the cloud.
The communication interval can typically be adapted from every 10 seconds up to 1440 minutes, depending on the needs of the individual solution. This makes LegacyLINK suitable for both monitoring, status reporting, and control tasks, where Driftssikkerhed, flexibility and High complexity are important requirements.
LegacyLINK is an important part of the foundation behind GSMCloud and is still used in many products and installations, where tried and tested technology, stable communication and Long-term operation are central elements. The protocol is particularly well-suited for solutions where a simple and well-tested communication model creates high stability and easy integration.
NB-IoT is an efficient communication technology for professional IoT controls, where Low power consumption, Stable connection and reliable data transfer is crucial.
The technology is based on a Narrowband LTE standard, developed for IoT devices that need to send small amounts of data securely and efficiently over the mobile network. This makes NB-IoT particularly suitable for solutions where the device needs to operate stably in the field for a long time.
With NB-IoT, our IoT controllers get a Robust mobile connection, which is suitable for monitoring, measurement data, alarm management and control tasks – also on installations without a traditional internet connection.
