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, it can define a range of Nodes you want to work with.
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
