Description

READY TO USE 

The CMi2120 is mounted inside the Landis+Gyr E350 meter and can handle up to 8 external connected M-Bus slaves. It requires no configuration in the field, which reduces both installation costs and the risk of handling errors. The CMi2120 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 CMi2120 can send meter values using FTP, HTTP and email. The email report feature prevents firewall and IT-structure implementation problems. 

 FLEXIBLE 
 

Exisiting and new L+G E350 meter models are all compatible with the CMi2120. Breaker functionality, interaction with meter display, M-Bus master, load watch and many more functions give the user a wide range of possibilities. 

 COST EFFECTIVE 
 

The CMi2120 provides one of the most cost-effective solutions for electricity and multi-energy 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 CMi2120 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.
