Whatever value is entered in the From Node # box will be the particular module Node data shown in the remainder of the main screen.
The value entered in the To Node # box does not have to be the actual “last” Node of the network. If you enter a value higher than what exists; an error message will display after you click the Refresh button. For the example shown; if there were only 4 Nodes installed and you entered 6, you would receive 2 error messages in succession after clicking the Refresh button
Clicking the + and buttons will increment / decrement the Node value in the From Node # box and display the module data for the new Node selected. Please note that if you increment past the value of the last physical Node installed, you will receive an error message
