    Hygain DCU-1 protocol from the programs that support controlling rotators. The ERC takes the task to move the rotator to the desired position or to stop the rotator while it is moving. Also changes of the direction are possible while the rotator is moving. The current position of the rotators is calculated from the measured rotor-feedback-voltage.
