CMeX11S M-Bus Master for 64 meters

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 CMeX11S adds a maximum of 64 additional meters to the number of meters supported by a CMe Series Gateway. With its unique IR pass through feature, the CMeX11S supports communication between four CMe/CMeX Series devices stacked side by side. Its advanced design, high compatibility and integration capability make the CMeX11S the ideal choice for remote meter reading in a wide range of applications and environments.
