Abstract

A meter device having supporting communications. The meter device may monitor a plurality of determinants. The determinants may be stored and displayed at the meter device. The meter device may support various communication protocols, such as dual communication protocols for simultaneous transmission via RS-485 and the Ethernet. The meter device may have a housing with a pair or more of communication ports. The device may have a data bus connector. The device may have a communication bus that can connect directly to a Java application control engine. Also, the device may have a din rail housing.

Claims
