Functional Description

Acquires signal from B-Alert X-series devices: 1) X4 (EKG + 3 channels of EEG), 2) X10 (EKG + 9 channels of EEG), 3) X24 (20 channels of EEG + EKG + 3 Auxiliary channels).

Note: The variable delay during Bluetooth transmission is expected to be +/- 12msec, for best results use B-Alert devices in wired configuration.
