Live Export

This operator incrementally exports its data to a file in real time while live viewing. Operand 1 specifies the variable that supplies the echogram data for export. Shortcut menu > Echogram displays Operand 1. The Live export operator regularly checks for new live viewing data and exports echogram data when new data is available. The operator is best used in a live viewing template's dataflow. Live export settings specify file location and other optional file parameters.

Live export may be used where Echoview is used remotely and data is sent to local network for assessment. Live export is designed to work while live viewing in Echoview and to work smoothly with COM live viewing support. Contact for further information.
