Acquisition from serial

[Skyfiller]

Hi,

I need to create a Vi in Lab that let me to acquire and write data that come from a serial port connect to an analizator of gas, that give information for example of concentration of O2, CO2, CO, NOx.....

The analizator has an own software, but I need to bipass it, and join them to others data ,that i'm now acquiring, in a single data file in Labview

I need also to choose which data acquire, because the data communicated are much more that i need.

I thank you for help, and I wait some answer.

You await an answer to what? I don't see any question.

There are some serial expample programs that come with LabVIEW. Start with them and if you run into any problems, post back with details. You would need to include the make/model of the instrument and if you get any errors, the error code that is being returned.

What kind of software came with the analyzer?  Is it a C DLL file?  Is it a Labview library (LLB).  Is it a bunch of Labview VIs?

What do you mean by you need to bypass it?  If it comes with driver software, why do you want to bypass it?  You would have to write your own and it is already written for you.

You could also check IDNET to see if there might already be a driver for your instrument, or one for a similar model.
