Designed specifically for industrial use, the PRO4 DCU MBUS offers reliable, secure high-speed wireless connectivity and remote access. It enables the integration of various industrial applications such as smart metering, industrial automation, substation management or the integration of Distributed Energy Resources (DER).

It comes with all the interfaces, protocols and management functions desirable in the world of industrial automation and smart grids. It is the preferred choice for mission-critical cellular communications of many large energy companies and IoT system integrators.

Cellular routers are highly effective for the implementation of reliable and extremely secure communications networks for remote substation SCADA, distribution automation, and metering applications. The routers collect data via Ethernet, RS485, Digital Inputs or Mbus and send it to a central server through the encrypted LTE cellular networks. For maximum security, OpenVPN, IPSec VPN services and firewall are also available. For higher levels of reliability, our cellular routers may be equipped with two SIM cards.

The PRO4 has a modular design, meaning that there are options for expansions. By default, it has 2 SIM card slots, 4 Ethernet ports, RS485 interface (terminal block), a microSD card slot, and a uUSB port for configuration and OTG functions. The open-source, Linux-based operating system OpenWrt® (optionally Debian) allows users to develop and run their own applications on the platform. It comes in an IP51 housing, supports DIN-rail, and the ports can be protected under sealable terminal cover.

Supports the most important industrial and network protocols like TCP/IP, Modbus TCP, Modbus RTU, Modbus Gateway, Mbus, MQTT, LwM2M etc. We also offer customization (protocols, interfaces, modules etc.) for large projects.

The M2M PRO4 MBUS has full remote access, monitoring and maintenance features.

Thanks to our Automatic Modbus Data Acquirer System (application developed for Modbus data collection) this router can also be used as a data concentrator.


Device Manager

On-demand OTA firmware and software upgrades may be remotely and securely uploaded to the cellular router from any point within the user’s network. The Windows-based Device Manager software allows faster deployment and guarantees the secure and proper functioning of the routers. State-of-the-art management functionalities including rapid device onboarding with bulk provisioning, easy administration, in-depth visibility of device status and, its performance metrics and security issues, logical groupings of devices into hierarchical structures for mass software and firmware updates.
