Parameters

SourceCh

The number of digitized and stored channels. This must match the setting in the VisionRecorder program, increased by 1 to account for an additional channel to hold marker information.

SampleBlockSize

The number of samples transmitted at a time. The VisionRecorder appears to send one block each 40ms, so SampleBlockSize should match SamplingRate x 40ms.

SamplingRate

The sampling rate as configured in the VisionRecorder program.

HostName

IP address or name of the host to connect to, typically localhost.

States

None.

getparams Tool

getparams is a command line utility that allows to obtain appropriate source module parameters from a host running BrainAmp's VisionRecorder.

On the target host, start the VisionRecorder program, check that RDA is enabled under Configuration->Preferences, and click the monitor (eye) button before running getparams with the host's IP address as the only parameter (when omitted, this defaults to localhost).

To direct the output into a file that can later be loaded into the operator module's configuration dialog, append a redirection to the command:

getparams localhost > myparamfile.prm
