Using RS 232C and DAQ 6009 to communicate and record data

don't worry about the rest of the project

Do NOT blame anyone here for your inability to do this relatively simple task. In your original post, I asked you to attach the manual. You did not. You then asked questions that can only be answered by someone who has a manual. If you don't have a manual, admit it and recognize that your task is impossible. If you do have the manual, read it and do some basic research. Then you can ask some specific questions when you write some code or try the serial examples that come with LabVIEW.

i didn't mean for it to sound like i wanted someone to do my project for me. i was just trying to see if i could get some guidance

Then provide more information. My impression is that you did not pay attention to anything I said and you haven't any done anything on your own.

i apologize i tried attaching the manual before but it's too large even as a zipped file. https://www.google.com/search?q=potentiostat+model+273&rlz=2C1RNKA_enUS0538US0538&oq=potentiostat+mo...  the first link is another version of the manual

I have been working hard on this project to the best of my abilities. I've looked at the example codes on labVIEW, tried fabricating my own code with both the DAQ and the serial connection, read the manual multiple times and only then did I decide to ask for help when none of that seemed to worked. I thought getting a second opinion on it would be helpful

So, according to appendix D, you need a null modem cable between the pc and instrument. As I mentioned in your other thread, this is critical information. Your plain 9-25 pin adapter will not work by itself. You have to make sure that tx on the instrument connects to rx on the pc and rx on the instrument connects to tx on the pc. Confirm the correct wiring and then attempt to communicate with a program such as hyperterminal before you write any code.

ok, i will try that. thank you.

So I established communication with it using teraterm and I tried running one of the example VIs on LabVIEW, the one for a basic serial read write and got the error 1073807246 that occurred at Property Node in VISA Configure Serial Port. It says that the resource is valid but VISA cannot currently access it. The device is old and researching other people who have used this device said that signal transfer takes longer for this device. The manual says that the potentiostat will send an asterik if the command is successful and a question mark if it is unsuccessful. I'd like to know if there's a way to program these commands into LabVIEW so that the program knows when to send the next command. I'd also like to know if I would need any external VI's to communicate with the potentiostat that are not provided with LabVIEW

I'd like to clarify that I am a college undergrad working on a research project for the summer. i'm a mechanical engineer so i don't have much knowledge of computers and device communication and i was given this project with minimal guidance from my mentor, who is the head of this research.
