# 1.3 Connections and us e (1) Please assemble the antenna of the Ground end first. (2) For connections and use pl ease refer to the diagram below.

Notes : (1) You can configure the Flight control system using the Assistant software on a PC or iOS mobile Device wirelessly over the link of the 2.4G Bluetooth Datalink, however you cannot upgrade the firmware of the Flight control system using this communication r oute. (2) W hen connecting a BTU module or a LED Bluetooth unit to the Flight control system to configure in the Assistant on mobile devices, as well as connecting a BTU module to the Ground end to use the iPad Ground station , the two Bluetooth communication li nks will not interfere with each other. (3) I f the Air end is changed to connect to a new Main controller, you should power cycle the Ground end. (4) M ake sure the LED indicator of BTU module is green after power on

, for specific usage details please refer to the BTU Manual. (5) For u sage of the PC Ground Station please refer to the latest Ground Station User Manual. I mportant : (1) If there are obstacle s between the ground and air end s then the radio signal of the 2.4G Bluetooth Datalink will be weak; please make sure t he antenna s are always visibl y unobstructed during the flight. Human body, trees, buildings or hills will disconnect the link between the A ir end and the G round end. (2) Make sure the antenna of the A ir end is pointing down, and the antenna of the G round end i s pointing upwards ; it ’ s better to put the G round end at a high place to get further transmission distance. (3) W hen using the ACE ONE Flight control system with the 2.4G Bluetooth Datalink, the Ground Station will connect to the Main controller 15s after powe r on.© 201 3
