Serial RS-232 Comunication in LABVIEW

[Bonitão]

I would like to know how to use the VISA blocks in LABVIEW 7.1 to perform a serial comunication using RS-232. I have a pH sensor that sends the pH level using the RS232 interface, how do I read this sensor with LABVIEW ?

Search the LV example for rs-232. Many examples of serial communication ship with LV.

Hi

Do a search on "serial" in the NI Example Finder in LabVIEW. The Basic Serial Write and Read.VI should be a good starting point.

Let me know if you need more help

What kind of ph-sensor are you using(manufacter)? Search on their homepage for LabView serial drivers
for the ph-sensor you are using, or earch for it on this website. If there are no Labview drivers
for this sensor you would need a programming handbook with all information about programming the
serial interface and write a LabView driver yourselve... better search for it first!

Where do i find the programming handbook ?

[Tom_Gloor]

In any way you have to contact the manufacturer of your ph-sensor. Ask them for LabView drivers
and if they don't have any drivers ask for a serial programming handbook.
