How to use a Jenco brand pH/Temp meter with labview via a serial port

[ACotton_88]

I have a Jenco brand pH/Temperature meter that I would like to use with Labview software.  I have never done any Labview programming before and am having trouble getting any communication between Labview and the device.  I know which serial port the device is using and I have the .dll file with all the functions used by the pH/Temp meter. Essentially what I am wanting is for the pH/Temp meter to send data to Labview and then have Labview interpret this data and send an output signal to run a pump and a heating element.  If anyone has any suggestions on examples/tutorials that would be especially helpful or any pre-written code that would suit my needs, it would be much appreciated.

The first steps have nothing to do with LabVIEW. If the vendor provides an application, use that to verify you are using the correct type of serial cable and the correct com port settings. A terminal emulator (i.e. Hyperterminal) might also be used if the vendor provides information on communicating manually to the instrument.

If you use a vendor provided DLL, it is unlikely that you will find any specific example for your instrument - just some generic examples on the Call Library Function Node. If you want to attempt to use LabVIEW serial functions, there are many examples of that. If you have problems with those, please provide the model number and manual.
