The MasterCella can be connected to the Boss range supervisory system through RS485 serial network. Wires are connected to 28 – 29 – 30. A small board needs to be installed on the main PCB to be able to communicate with the MasterCella. You can chose between either IROPZSEM10 or IROPZSEM30. IROPZSEM10 is only for supervisory communication. IROPZSEM30 can both be used for supervisory communication or repeater display.
