MUXM multiplexer is a concentrator for temperature probes TM and humidity probes TU. At each MUXM you can be connected up to max. 32 probes TM + TU. In case of TM 32 probes each having max. 50 measuring points you get a total of 1600 controllable points. The electrical connection between probes and MUXM was made by shielded cable, while connection between MUXM and AGRITHERM-50 control unit was made by bipolar shielded cable for communication data. MUXM configuration was made via removable module VL701 and operations are displayed by O-LED display. The serial network can connect up to 63 MUXM.
