You have the possibility to communicate directly with the NeXus devices without the use of the BioTrace+ software. The GDI DLL gives real-time access to data coming directly from the NeXus-4, NeXus-10 or NeXus-32, via Bluetooth or USB. The DLL can be used for direct access within other applications. In comparison to option two, this option requires programming of data processing, filters, etc.

The DLL contains three functions:

  • Init: Initializes the DLL and connects with the NeXus; during initialization a callback function address should be passed. This callback function will be called by the DLL for every data sample that will be received from the recording device;
  • Start: Starts data acquisition at the requested sample rate;
  • Stop: Stops the data acquisition.

The DLL is located within a demo-project and is made available after signing a non disclosure agreement (NDA) and paying a fee per license key. The how-to use information is included in the source files after opening the project in visual studio and on request there is a short video available of the demo application and the basic usage of the DLL.
