With a Digi XBee in API mode connected to a computer over USB, launch the Digi XCTU program. Add this Digi XBee to the Radio Module list using the plus icon in the upper left. Once that radio is in the list, click the Network mode icon in the upper right to display the mapping screen. The mapping screen will help the developer explore and understand their network. It shows which modules are connected, what their addresses are, how they are linked to each other and the strength of those connections. The network can be scanned continuously if desired. This will create a live, real-time map to help understand how the network changes over time. It is especially useful for tracking down and fixing intermittent trouble-spots. It’s simple to get started. Click on the Scan button to begin a continuous scan of the Zigbee network. It will start by discovering the locally connected module. After that, it will scan the network for the remaining modules, then query each, one at a time, to determine their neighbors and connection strengths. Whenever additional modules are discovered in this process, they are added to the map and the scan will be extended to include them.
