6.7.3.1 Sync In in MT Manager:
When Sync In is in use, after configuration, and when ready to record, users should click
Record, to prepare the system for the external trigger. The record icon changes from the
normal red dot to one with the pause symbol overlaid:
6.7.4 Sync Out
Sync Out is the command that enable the Xsens system to send a trigger pulse for
synchronisation purposes. A control signal is sent via the Awinda Station, from MT Manager
to the third party hardware. As with sync In, a combination of events are possible, based on
a number of parameters.
Event
Description
Start Recording
Upon clicking the record button in MT Manager, the Awinda Station
starts the recording and consequently sends a start recording trigger to
the third party system.
Stop Recording
Upon clicking the record button in MT Manager, the Awinda Station
stops recording and sends a stop recording trigger to the third party
system.
Go to Operational
This feature gives the maximum flexibility because it speeds up the
preparation of the instrumentation and the subject (if synchronising at
the time of the operational mode) or, once the preparation is done, to
synchronize and record data only when strictly necessary (if
synchronising every time you record)
Frame Transition
Measurement
A frame transition at the station can be used to give a signal to the
external system, indicating the end of the strap-down integration
interval over which data is calculated. Selecting this option, the frame
transition is sent from the moment that “Start Measuring” is selected.
Frame Transition
Recording
See Frame transition Measurement
Selecting this option, the frame transition is sent from the moment
that a recording is started. This is a very useful option to implement, to
ensure that during a recording, the clocks of the synchronised systems
are known, ensuring that any drift can be compensated for.
The default polarity of the output line is low. However, for input triggers that assume high
polarity, the polarity of the line must be set beforehand. This is possible, using 'Go to
operational' with a polarity positive pulse and infinite pulse-width.
A number of parameters can be set for each action:
