External UART Modem - 4G Modem

AKCP External UART Modem – 4G Modem (Voice Call Support)

The AKCP External UART Modem is the optimal solution for professional environmental monitoring at remote sites or as a reliable backup connection. The SPXN and SP2+ base units feature a dedicated port for connecting this external 4G modem, which has been specifically developed for customers needing cellular communication as a primary or secondary connection.

Professional Monitoring Solution for Critical Applications

This advanced data modem is specifically designed for use at remote locations, where AKCP base units are deployed for continuous monitoring of critical environmental factors. The external UART modem enables seamless communication over the mobile data network, even when no conventional LAN connection is available.

The solution provides complete flexibility in sensor monitoring and ensures that your critical systems remain fully monitored and protected even in the most remote areas. With integrated SMS notifications and email alerts, you are immediately informed about critical events, regardless of where your monitoring devices are located.

Advanced Communication Features

The external 4G modem supports state-of-the-art communication protocols and offers SMS, email, and MMS notifications with real-time sensor data. The innovative text-to-speech function enables automatic voice calls with confirmation support, allowing critical alarms to be delivered by phone.

Particularly noteworthy is the VPN connectivity, which enables secure remote access to the monitoring devices’ web interface. The integrated OpenVPN client functionality establishes high-speed connections to the AKCPro Server as well as to other third-party OpenVPN networks, ensuring maximum flexibility and security.

External Antenna for Optimal Signal Strength

The modem is supplied with a powerful external antenna specifically designed to boost signal strength in areas with weak network coverage. This 3-meter antenna with magnetic mount and SMA connector can be optimally positioned to ensure the best possible connection quality.

The antenna’s robust construction is designed for operation in extreme temperature ranges from -40°C to +85°C, providing reliable performance even under the harshest environmental conditions.

GPS Tracking and Geolocation

A particular strength of the system is the optional GPS antenna, which can be used for mobile asset tracking and automatic geolocation of static sites. This feature enables precise mapping in AKCPro Server and greatly simplifies the management of distributed monitoring infrastructures.

Compatibility and Easy Integration

The external UART modem is fully compatible with the following AKCP devices:

• SP1+ Professional – Compact entry-level solution
• SP2+ Professional – Advanced monitoring platform
• SP2+ Professional LCD – With integrated display
• SPX+ – High-performance monitoring system
• SPXN – Latest generation of monitoring technology

Integration is achieved via the already built-in support in the web interface, with user-friendly dropdown menus for quick and easy configuration. This allows even non-technical users to get started without any problems.

Heartbeat Function and Data Distribution

The innovative heartbeat function is integrated directly into the base unit and enables the timed distribution of SMS, email, and HTTP data to remote web servers via the GSM network. This function ensures regular status updates and guarantees that the monitoring systems are functioning properly.

Regional Availability and Network Support

The modem is available in two regional versions:

• EU Version: Optimized for European network operators such as Deutsche Telekom and Vodafone, with corresponding frequency bands for maximum compatibility.
• US Version: Specifically configured for North American network operators such as AT&T and Rogers, with the appropriate frequency specifications.

Technical Advantages and Reliability

The external 4G modem offers significant advantages over internal solutions: It can be positioned separately to achieve optimal signal strength, is easier to maintain, and can be replaced as needed without affecting the main monitoring unit. The UART interface ensures stable and reliable data transmission.

The robust design and extended temperature ranges make the modem ideal for industrial applications, data centers, telecommunications facilities, and other critical infrastructures where continuous environmental monitoring is essential.
