Digi XCTU connects with a designer’s entire Digi XBee® network over the air. A single XBee connected via USB provides secure access to configure, manage, map, update, and test networked radios wirelessly. Using Digi XCTU over the air is effortless. Simply click the network icon for the local radio and it will scan for all the Digi XBees on the network, adding them to the Digi XCTU interface in a list or graphical map. Hundreds of Digi XBee modules are now at a developer’s fingertips. Even when they’re behind a locked door or way at the top of a utility pole, secure control is within their hands.
