CMeX10S-12S is an M-Bus Master which, by providing additional drive strength, extends the number of meters an Elvaco CMe Series Gateway is able to use. The product is equipped with a unique IR Pass Through feature which enables up to four CMe/CMeX Series devices to communicate via IR, by stacking them side-by side. The product also supports integration with existing M-Bus systems through RS232.
Product information "CMeX12S M-Bus Master for 128 meters"
The CMeX12S model is a reliable M-Bus master that extends the number of meters that can be used by a compatible M-Bus gateway. This device is therefore a fundamental component of a modern M-Bus technology-based measuring system infrastructure. The reliable operation of this M-Bus Master for 128 meters rests on a unique IR pass-through feature that allows data to be transmitted to the M-Bus gateway without the need to install any additional cables
