	The BCI source module that receives the data from the acquisition is the server so it must be in listening mode before the acquisition unit starts to save data (data is sent only during recording).

	A packet of data is structured in 2 sections the first is the header and the second is information data. The first packet sent from the client is the header of an EEG Micromed trace and is read for condition checking. If a note is added in SystemPLUS it is sent as a note packet to the source module. If a digital trigger is sent the trigger code is sent to the source module in two ways: the complete code and a bitmasked code.
