Reading RS232 input tutorial

[jmarotta]

Hello all,

Does anyone have good recommendations for an RS232 communication tutorial?  I'd like to write a VI that accepts readings from a scale with RS232 output, and is able to do various things with the data.

Thanks,

Joe

Hey Joe,
Here is a link to the NI Development Zone on Serial Instrument Control. There are also some well documented examples for serial communication in the LabView Example finder.

LabView Examples:

dear friend,i am working on a project where i have a gwinstek GDM-396 multimeter to be conneted to an RS 232 port.
watever voltage is recorded from the multimeter should be trasmitted on a waveform chart in labview. i have written a labview program but i am always getting a 0 output.i have already set the parameters(parity,baud rate...) of the multimeter in the labview also. i am quite new to labview. help me please to get that output voltage in labview.
please find attached my program.i am using labview 7.0.
thanks

You hijacked yet another thread and you did not post any code.

Did you look at the existing Instek drivers to see if they have anything in common with your model?

The programming gude can be found under the downloads section. http://www.gwinstek.com/en/product/productdetail.aspx?pid=39&mid=80&id=204

Unless there's a driver for that specific model, I'm going to guess it's probably not going to work. You are just reading back the values of the 7 segment displays.
