Connect connector connector connect This will connect differential data output lines differential data input lines. Both clock pins load lines outputs from board. Therefore, connect clock load lines from serial port connector another serial port connector DEMDSP102/202. this test, only lines described connected together. With these connections made power applied, analog signals applied input connectors will reconstructed respective output connectors.
