You have the option to select any one of eight trigger 

codes to insert into the recording. These will be inserted 

in the same way as a normal trigger sent from our 

Wireless StimTracker. However, we recommend only 

using the trigger for precision event marking, and to use 

these software triggers for general annotation.

 Allows you to choose which port to receive 

triggers.

•  Start TCP Receiver

 Starts the receiving service.
