In this page we describe how you can interact with NIC (Neuroelectrics Instrument Controller, the software for control with NE devices) using other software.

Sending Markers to NIC from other software or hardware
NIC provides a server that other software can connect to in order to receive markers. Those received markers are synchronized with the EEG streaming for further analysis.
This NIC server is running in the TCP/IP port 1234. Up to five clients can simultaneously send markers to NIC by making a TCP/IP connection to this port.
Once a client is connected it needs to send the following string in order to send a marker:
<TRIGGER>XXXX</TRIGGER>
Where XXXX can represent any integer number different from zero (from -2147483647 to +2147483647). This marker will be co-registered in the output files generated by NIC to the corresponding EEG sample. For instance, in the output tabulated text file, there is a column just after the timestamp that is filled with zeros. When a marker is received its corresponding number is set to that column.
