DataSocket for live data transfer
DataSocket is a program interface designed for live data exchange between
different applications on one system or even on separated computers connected by
a TCP/IP network. The Wavefront Sensor GUI application is able to send its
measurement results to a computer or database receiving the data for further usage.
Both, measured Wavefront and Zernike parameters including the complete data
arrays as well as the appropriate setup data are available via DataSocket transfer.
NOTE
The Data Socket implementation on the Wavefront Sensor is not designed to
control measurement parameters of the Wavefront Sensor! Only sending
measurement data to a DataSocket receiver is implemented.
See this website http://www.ni.com/datasocket/ for details and applications of
DataSocket.
The following configurations are feasible:
a) PC A runs the Wavefront Sensor application which sends the measurement data
to the local DataSocket server running on the same machine. An application on
the same PC A retrieves the data.
b) PC A runs the Wavefront Sensor application which sends the measurement data
to the local DataSocket server on the same machine. An application on another
PC B retrieves the data. PCs A and B are connected via a network.
c) PC A runs the Wavefront Sensor application which sends the measurement data
to the distinct DataSocket server running on PC B. An application PC B retrieves
the data.
d) PC A runs the Wavefront Sensor application which sends the measurement data
to a DataSocket server running on PC B. An application on a third PC C
retrieves the data. All PCs A, B and C are connected via a TCP/IP network.
The following explanations are related to the National Instruments DataSocket
server. It comes with the LabWindows/CVI and LabView packages or is available
from the National Instruments download website

Starting the DataSocket server
When the National Instruments DataSocket server is installed on a local machine it
can be started from the Start prompt of the PC:
