23.7 Synchronization Examples
23.7.1 Start and stop recording of third party devices using single pulse
Third party device starting and stopping recording of Xsens system, on Line 1 of the Sync In port.
Click “Add”
Select Sync Type Start
Recording
Select Sync Line: In 1
Pulse Polarity: Rising Edge
10
Skip First = 0
Skip Factor = 1 (so that
every other pulse will start a
recording in MVN Studio)
Trigger Once: Unchecked
11
Click “Add”
Select Sync Type Stop
Recording
Select Sync Line: In 1
Pulse Polarity: Rising Edge
Skip First = 1 (first trigger
starts recording, so it should
not also send a signal to stop
- or this causes confusion for
Awinda Station)
Skip Factor = 1 (so that
every other pulse will stop a
recording in MVN Studio)
Trigger Once: Unchecked
The above example indicates how to allow a signal of 3.3V enter the Sync In 1 port, of the Awinda
Station. The first upward going pulse (and subsequent odd numbered pulses), received on the Awinda
Station, will start recording (Polarity = rising edge). The second upward going pulse (and subsequent
even numbered pulses), received on the Awinda Station, will stop recording.
23.7.2 Start and Stop Recording Third Party Devices with Infinite Pulse Width
It is of course also possible, to configure that for example the upward rising edge causes the start of
recording and the negative direction edge causes stop recording, this may be useful in the event that a
third party devices needs to be active high to record data.
To do this, the following settings should be input:
10
Note that this setting depends on the signal from third party system.
11
To ensure that a series of recordings can be made.
