Patent ID: 8223892

Claim:
A multi-channel data acquisition system providing inter-channel communication, comprising: a plurality of data acquisition channels comprising: a first data acquisition channel configured to receive and process a first data input signal to produce a first processed data signal, the first data acquisition channel comprising a first data output; and a second data acquisition channel configured to receive and process a second data input signal to produce a second processed data signal, the second data acquisition channel comprising a second data output; and a data exchange layer coupling the first data acquisition channel and the second data acquisition channel, the data exchange layer configured to transmit the first processed data signal from the first data acquisition channel to the second data acquisition channel, and the data exchange layer configured to transmit the second processed data signal from the second data acquisition channel to the first data acquisition channel, wherein the first data output and the second data output are separate, and wherein the first data acquisition channel is configured to place a first output signal on the first data output and the second data acquisition channel is configured to place a second output signal on the second data output, the first output signal based on the first data input signal and the second data input signal, and the second output signal based on the first data input signal and the second data input signal.
