Elvaco - CMi2130 - Integrated MCM for Itron ECHO II and CF 51/55, Gateway for Mobile Network
Elvaco – CMi2130 – Integrated MCM for Itron ECHO II

CMi2130 is mounted inside an Itron CF 51/55/ECHO II to act as a costeffective M-Bus Metering Gateway. The CMi2130 uses standard open protocol for fast and easy integration with any existing system. The MCM is configurable by SMS and can receive software updates over the air. Its flexible and versatile design makes it simply the most powerful GSM/GPRS solution for district heating on the market.

READY TO USE

Mounted inside the Itron ECHO II/CF meters the CMi2130 can handle up to 8 external connected M-Bus slaves. The CMi2130 requires no configuration in the field, which reduces both installation costs and the risk of handling errors. The CMi2130 unit delivers immediate installation status and starts logging meter data directly after power up.

STANDARD OPEN PROTOCOLS

The standard open protocol design enables fast integration into existing billing and reporting systems. Transparent M-Bus communication with GSM and TCP works with any software supporting the M-Bus standard. The CMi2130 can send meter values using FTP, HTTP and email. The email report feature prevents firewall and IT-structure implementation problems.

FLEXIBLE

The CMi2130 has a flexible design with many integration and communication possibilities, which allows a wide range of customer implementations. Special needs can be satisfied by adding new functionality to an existing installation using the remote update facility.

COST EFFECTIVE

The CMi2130 provides one of the most cost-effective solutions for district heating on the market. The integrated solution reduces the amount of equipment necessary in the field, which lowers both installation and initial setup costs. The quality and the number of options available serve to minimize the overall cost of the product over the course of its use.

FUTURE PROOF

The CMi2130 is built on standard SUN Java™ platform technology, a worldwide standard. Core platform and libraries are designed and tested by leading software companies. Updates and patches can easily be performed remotely, preventing unneccessary service calls or on site visits.
