how do I use display a measurement from a load cell (attached to my serial port) in a front panel

[SPY07]

I have a load cell attached to 2 serial ports on my WIN200 PC. I am using LABView7. I am a newbie and I just want to be able to display the measurement data in a graph on my front panel

First you'll have to convert the string received from each serial port read into numbers. Use a Scan From String function on each serial port data to do this. To plot in real-time, the simplest thing to use is a chart. Bundle together the two numbers output from the Scan From string and wire the bundle to the chart.

Hello -

I have attached a program which performs what Dennis discussed. You will need to modify it for your specific instance. VISA Configure Serial Port needs to be set for your specific ports and you may need to change the byte count of VISA Read.

Being new to LabVIEW, you may want to take a LabVIEW training course.

Good luck with your project and have a great day!
