Antenna The tail of the Antenna should be pointed downward and unobstructed to ensure the communication distance. · PC Ground Station · 2.4G Bluetooth Datalink Assistant Software · Assistant Software of Flight control system USB port Connect to a PC via a USB cable to use the PC Ground Station or configure the 2.4G Bluetooth Datalink in the Assistant Software. CAN-Bus port Connect the BTU module when using the iPAD Ground Station DC power port Connect DC power, you can choose one of the USB power supply or DC power supply to provide power for the Ground end. The Ground end Distance between the two ends should be more than 1.5m Communication& power supply port Extra power supply port · 3S-6S Battery · 9.9V~25.2V DC power - + · iPAD Ground Station · Assistant of Flight control system + - 90 o To Flight control system To any CAN-Bus port on ACE ONE, WKM , NAZA-M， NAZA-M V2 The Air end Antenna The tail of the Antenna should be pointed upwards and unobstructed to ensure the communication distance. 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 route. (2) When 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 links will not interfere with each other. (3) If the Air end is changed to connect to a new Main controller, you should power cycle the Ground end. (4) Make sure the LED indicator of BTU module is green after power on, for specific usage details please refer to the BTU Manual. (5) For usage of the PC Ground Station please refer to the latest Ground Station User Manual. Important : (1) If there are obstacles between the ground and air ends then the radio signal of the 2.4G Bluetooth Datalink will be weak; please make sure the antennas are always visibly unobstructed during the flight. Human body, trees, buildings or hills will disconnect the link between the Air end and the Ground end. (2) Make sure the antenna of the Air end is pointing down, and the antenna of the Ground end is pointing upwards; it’s better to put the Ground end at a high place to get further transmission distance. (3) When using the ACE ONE Flight control system with the 2.4G Bluetooth Datalink, the Ground Station will connect to the Main controller 15s after power on. ©2013 DJI Innovations.
