RS232 Communication with Mastech MS2203

[kennycaldas]

Hi,

I'm trying to visualize the data from a Mastech MS2203  in LabVIEW using RS232 serial port.

I have the initial config settings (baud rate, parity etc...) that I could get using PORTMON, but I'm still no sure what to do next.

I couldn't find the serial protocol for this device, but I have their software that does exactly what I'm trying to do.

I have attached the software display and the PORTMON data that I got while I was running the program.

Does anyone have any ideas on what I could do next?

Thank you!

Need to get the serial protocol specification from the vendor of the Mastech MS2203 to know how to parse the hex data.

You will find your answer here: http://www.multimeterwarehouse.com/MS2203Protocol.pdf

That's not exactly readable.

Thank you Matthew!

With that file and a little help from Google Translate I could read the voltage in LabVIEW.

Glad I was able to help out.  Good luck!

Dear  patel1508,

I don't have the code for this multimeter anymore, sorry.

But I remeber I used the code provided in this post as a starting point for my application:

You'll have to change some parameters to work with the mastech device, but you'll be able to have a pretty good idea on how to do it

hope that helps.
