The multiplexer MUX is a concentrator of the signals coming from the temperature probes. At each MUX can be connected up to 8 probes, each having 12 measuring points, for a total of 96 controllable points. The electrical connection between the probe and the MUX is made with a FTP (24AWG) cable, while the connection between the Mux and the control unit Agritherm is realized with FTP (22AWG) cable suitable for digital data communication in RS485 serial network. The configuration of the MUX and the connected probes self-acquisition is done via the 3 buttons on board and operations are shown on the internal display. In serial network can connect up to 63 MUX.The communication protocol of the MUX is compatible with earlier detection, control and display temperature systems previously supplied by SGM LEKTRA.
