External triggering of V120 Duo and monitoring for trigger using NatNetSDK
Posted: Fri Nov 09, 2018 6:09 am
Hi All,
I am trying to synchronise eyetracking data recording and mocap data recording. In order to do this, I want to send a TTL trigger from the eyetracking software on one PC to the I/O box of the V120 duo. Ideally, I'd like for matlab to start recording the mocap data (on a different PC to the eyetracking software) when this trigger is sent. We have tweaked the matlab sample in the SDK to allow us monitor and save the coordinate data for a rigid body but aren't quite sure what to get it to listen out for in terms of the trigger.
My questions are:
1) Is it possible to externally trigger the v120 duo via the BNC connection on the I/O box?
2) Is there a way to monitor for this trigger using the SDK?
Any help would be greatly appreciated as we are very new to all things motion tracking.
Thanks a lot,
Tegan
