Synopsis
The IOTech is a user expandable 16 analog channel and 24 digital channel digital acquisition device (DAQ) from Measurement Computing. The contributed source module acquires raw signals from the DAQ in real time for use in BCI2000 with 16 bit precision.
BCI2000 has also been tested with an additional 48 channel expansion module, enabling acquisition of 64 channels of data.

Compile the # module using CMake and your compiler. The resulting #.exe should be placed in the prog directory automatically.
Parameters
- SourceCh represents the total number of channels to be logged from the source module.
- SampleBlockSize should be set equal to the size of the sample block pulled from the device.
- NOTE: Only specific combinations of SampleBlockSize and SampleRate are valid! See #Valid Operating Modes
- SampleRate determines the rate at which the device samples data.
