iWorx has developed a proprietary Serial Interface technology called iWire. iWire devices enable unparalleled expansion of your laboratory recording equipment by simply plugging in an iWire compatible device. The iWire-B3G is furnished with the iWorx TA Recording Module. It allows the recording of up to three channels of ECG, EMG or EEG as well as GSR ( skin conductance ) from a single iWire input on the recording Module. A traditional data recorder would require 4 additional recording channels to accomplish this.
