CMeX13S is an M-Bus Master which, by providing additional drive strength, extends the number of meters a 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. CMeX13S also supports integration with existing M-Bus systems through RS232. Cable is not included.

The electronics of the CMeX13S M-Bus Master for 256 meters are housed in a durable, robust polyamide casing to ensure fault-free operation. The M-Bus Master is mounted on a standard 35 mm DIN rail. This makes the device easy to install with minimal effort.

The user interface of the CMeX13S M-Bus Master for 256 meters consists of four coloured LED lights that provide a simple, direct visualisation of the current status of the device. The green LED shows that the M-Bus Master is powered on, while the red LED indicates that there is an error message preventing the device from functioning properly. The two yellow LEDs light up to indicate that M-Bus data is currently being transmitted from or to the M-Bus Master.
