CMe3000 M-Bus Gateway for Fixed Network

CMe3000 is a cost-effective M-Bus Gateway for Fixed Network which acts as a communication tunnel for M-Bus meters and enables them to communicate with a receiving system. The product is equipped with an IR interface which enables it to communicate with other devices from Elvaco's CMe/CMeX Series as well as ABB electricity meters without using any cables. It is also compatible with all other meters using the M-Bus protocol. Through its integrated web interface, CMe3000 can be configured and updated remotely without having to visit its installation site.

The CMe3000 - M-Bus Gateway for fixed networks, is a smart, modern but still cost-effective level converter that acts as an interface between the M-Bus meters and the Ethernet TCP/IP communications infrastructure. The CMe3000 is a transparent gateway between wired M-Bus devices and the higher-level system using TCP/IP network.

The CMe3000 - M-Bus Gateway for fixed networks is a high-quality entry-level model in the field of M-Bus Gateways and provides all the essential functions required by a modern metering infrastructure. One key benefit of the M-Bus Gateway is its plug-and-play concept, which includes an intuitive, easy-to-use web interface. This online interface is used to monitor, maintain and configure the M-Bus Gateway remotely and therefore plays an important role in effective network monitoring and building automation systems. In addition, the CMe3000 can be updated remotely via the integrated web interface. Because of its compact size, the M-Bus Gateway takes up very little space and is easy to install.

Alongside its practical web interface, the CMe3000 - M-Bus Gateway for fixed networks also has a physical user interface that clearly indicates the current status of the M-Bus Gateway. An integrated LED lights up in different colours to show when the M-Bus Gateway is switched on or in Ethernet mode. A red LED alerts the user to the existence of a fault. The CMe3000 - M-Bus Gateway can be fully configured via its accompanying web application. The CMe3000 - M-Bus Gateway for fixed networks also has a push button for factory reset. This is particularly useful if repeated errors occur that cannot be resolved by simply reconfiguring the gateway. However, the M-Bus technology is highly reliable, which means that recurring errors are very rare.

Find out in more detail about the CMe3000 - M-Bus Gateway for fixed networks by contacting the competent and experienced team at Elvaco. If you are interested in the product, please send us an enquiry with the specifications of your metering project.
