Change Icon is selected and the Input Channel you are connecting is an Analogue then you will also be asked to specify the percentage change that needs to occur before the Analogue value will be sent For example a change of 10 will cause a transmission to occur every time the input value increases or decreases by 10 of full scale or more since the last transmission If the State Change Icon is selected and the Input Channel you are connecting is a Pulse then you will also be asked to specify the number of pulses that need to occur before the count will be sent For example a value of 5 will cause a transmission to occur every time the input value increases by 5 or more Note the count is cumulative so a total of 5 or more will cause a transmission Each time you complete an entry the Connect button must be pressed This transfers a summary of the connection made to the Connections area on the screen The connection process can be repeated for each Input Channel by repeating this process If you wish to remove delete any connections simply highlight the appropriate connection in the Connections Made area on screen and press the Remove button cilintithed Peraneck aide Manger 704 Node Coniston Setup Menibor Tami Hodues Avadable J Cad 1 ADH for bosd J Cad 2 IRDH Z12 2 Digia pie 3 1 8 a Puka gada FENT H Gad 3 ADH 20 a Depa puts 031 5 a Fuba inpats PST 6 Screenshot 12 C
