Serial port data collection

[hotha_rkz]

I am getting a signal from a scan. I do not know how to use this signal to collect the data from a scan. I can save only one reading. What I need to do to collect the whole scan and save in one file.

Your post is not sufficiently specific to allow us to provide you with much help.

The Subject refers to a serial port which you do not mention in the text. Is "a signal from a scan" what you get on the serial port?  

A serial port transfers bytes, many times as ASCII characters. Chances are that your instrument does not generate the data that way. What is the format of the data received from the serial port? 

How is "the whole scan" related to "a signal from a scan" and to the data you want?

Please post the VI you have developed so far. Include some data such as "a signal from a scan". Tell us what the data corresponding to that signal should be. Also tell us what needs to be included in "the whole scan".

Scan from what?  An Instrument?  What instrument?  What does your code look like?

I am measuring the wave length using a wave meter. I am using labview to read the data and collect the wave length region. the program can read one wave length and save it. I want to konw how I can use this program to collect the whole wave length readings at once after buffering
