CMeX10S-13S 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.
The CMeX13S model by Elvaco is an M-Bus master that increases the maximum number of meters from compatible M-Bus gateways to 256. As a fundamental component of the M-Bus meter remote reading infrastructure, the CMeX13S uses a unique IR pass-through feature that allows data to be transmitted to the M-Bus gateway without the need to install additional cables.
