-Station supervisor software should generate data file outputs for an webserver which serves station status information. This telemetry information will be displayed in the web.  Web access is primary diagnostic interface. Terminal interface to measuring node is secondary backup interface.
+We will not have direct IP connectivity from Internet to stations. Station supervisor software should generate data file outputs and upload these data files to an web server which serves station status information. Telemetry information will be displayed in the web on separate central web server.  Web page served by central status server is primary diagnostic interface.

-Data-upload is another daemon, which manages storage space on measuring node.
+=== Node software ===
+Node hardware will run a data-processing utility ([[en:radio-observer]] for example), data uploading and distributing utility and station-supervisor daemon. Station-supervisor acts as watchman which checks proper functioning of whole measuring node. Data-upload is another daemon, which manages storage space on measuring node.
+Station-supervisor does not have a screen output. Screen output may be served by client program ssmon (Station Supervisor Monitor) which generates interactive status screen after connection to Station Supervisor server.
