7 Hybrid tracking
Please select an appropriate channel for each dongle now. The selected dongle will
change its channel accordingly and likewise all assigned sensors. Do not set both don-
gles to the same channel or on occupied frequencies from other devices in range.
Z
The default channels for all dongles and sensors are 35 and 55 (out of
80). In case these frequencies are already occupied by other devices
in range (e.g. WLAN), connection problems may occur. ART recom-
mends to scan for available channels and to select free channels ac-
cordingly. A minimum distance of 10 channels is mandatory between
dongles, and recommended from otherwise unavailable channels for
optimum connectivity.
7.1.2 Connecting the wireless inertial sensors
This needs to be done initially - in case the sensors are already connected please skip
this step.
All ART pre-calibrated targets are delivered with their corresponding optical target geome-
tries stored inside the inertial sensor. Thus when adding the recognized inertial sensors,
all corresponding target geometries are automatically added to the tab ’standard bodies’
in the menu Body Administration (Shortcut:F8) and the sub-dialogue Hybrid Bodies of the
menu Inertial Sensor Settings respectively.
Z
Please ensure that all sensors have been charged or alternatively at-
tach the sensors to the supplied charging hub prior to the following
steps.
Turning on/off wireless inertial sensors Turn on all sensors by pressing their corre-
sponding buttons. The status LED will turn green.
All inertial sensors are turned to stand-by mode after a pre-defined idle time, which cor-
responds to the selected wake-up mode.
via: radio (idle time: 1 min.), i.e. the sensors are switched on as soon as they are
addressed by the controller.
via: tapping (idle time: 3 min., older sensors only), i.e. the sensors are switched on by
tapping on the sensors with your fingertip or tapping the sensors on a hard surface
(e.g. table).
via: USB/button (idle time: 10 min.), i.e. the sensors are switched on by pressing the
button on the sensor for 3-4 seconds or by connecting them to the supplied charging
hub.
Z
For optimal battery life, ART recommends to switch all sensors to
wake-up mode "USB/button" when not in use for a longer period of
time.
