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:
