CMeX10S 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. CMeX10S also supports integration with existing M-Bus systems through RS232.
Product information "CMeX10S M-Bus Master for 32 meters"
The CMeX10S is an M-Bus Master in the CMe Series, which can, as an extender, read 32 additional meters for a gateway. It can reach meters with an M-Bus cable length of up to 5,000 metres and reliably forward the collected data.
This model enables the efficient management of meter data in different applications and environments. The unique IR pass through feature supports communication with up to four CMe/CMeX Series devices. The CMeX10S provides a scalable solution for remote meter reading and provides maximum efficiency in meter management.
