(e.g. the timing of the TMS stimulation) can be directly saved into the same data streaming.
(e.g. the timing of the TMS stimulation) can be directly saved into the same data streaming.
The scheme above shows the required connections to realise this type of synchronism in case:
1. The third-party device is working as master: red connection;
2. The Wave Plus system is working as master: blue connection

.
NOTE THAT if you want synchronize the Wave Plus system with third-party devices collecting the
EMG signals from the Wave Plus analogue port, you should also consider the 13 ms delay related to
the Wave Plus analogue output. In this case you should correct the recorded data in order to remove the
13 ms delay. NOTE THAT the 14 ms delay is constant and it can be easily removed by shifting the
temporal sequence in the following way:
