473 Dew Point Mirror/sweat system

[kmous]

My organisation bought  new sweat rate system and I would like to know and figure out how we can collect the data? We basically just need a way of recording the output that is shown on the screen display of the dew point sensor. I can make that in VB with no problem , but is it possible in LABVIEW ?

Thank you

I attached the manuel in case someone want to see the system's picture.

I would use VISA to communicate with the device using RS232 commands.  There is a wizard that makes it really easy to make sure your serial commands are formatted properly.  It makes it pretty easy to create a simple set of drivers.

Hi bruce

what is VISA ?  what do u mean ? a better solution than VB or Labview ?

Thank you

[RavensFan]

VISA is a part of LabVIEW.  It is on the Instrument I/O palette.

VISA is a high level interface for RS232, TCP/IP, and other communication.  It is installed as part of LabVIEW.

So , you guys recommend me to use Labview to do that ?

[kmous]

Yea I just installed it was not there , weird....so now how can i proceed if i want to use VISA ?

I just need to understand how that works  and i will read about it.

Look in the example finder for Basic Serial Write and Read and Advanced Serial Write and Read examples.

I am lookin at them but what i want to understand is what i really need to have to get started ?

I have my Laptop with LV 8.2 installed , my Hardware and my RS232 cable ? 

of course i have to connect my hardware to my pc using Rs232 serial.

should i install the driver first ? or VISA WIZARD will do it fro me bu selecting the .ini file ?

that's how i want you guys to help , just point me to the directions 🙂

thank you

There is no driver, there is no VISA wizard.  I don't know what .ini file you are talking about.

1.  If they have software, install that, connect your cable, and run it.  Just to make sure everything works.

2.  Read the manual.  Serial communication starts on page 20.

3.  Use Hyperterminal to connect to the device.  Try out a few basic commands in the manual and see if you get the appropriate response.

4.  Use one of the examples in LabVIEW and try the same thing.
