waveform graph problem

He is just spamming the board and not listening to what anyone has to say.

i'm sorry mate,its my helplessness that cause me to do that,i'm not getting the right solution.

yea i tried what you suggested,i did probe the string output, i got a '1' for only when i start running the program,then 

it returns and remains to zero. I'm confused,stressed....

on top of that i got to do a presentation on that next monday. its only part of my project,if this does not work,the whole project fails..:s

i'm sorry for that,i did not realise i was annoying the board. I tried everything that i was told ,but alas,it still would not work.

I'm keeping my fingers crossed expcting to get a reply from someone who has already worked on something similar like that to mine.

Sorry again mate

But in some of those threads, you have not responded to requests for more info and starting a new thread does not help anyone.

As noted in the manual that is linked to here, your baud rate is incorrect and niether is your flow control. It would not surprise me if your cable is incorrect as well. If you are using a null-modem cable, try a straight through one and vice versa. In your program, you are doing a write and that is clearly not necessary per the manual. Try the program from Instek that is also available from the above link. If that does not work, then it is senseless to try LabVIEW. When you do have communication established, you will then have quite a bit of work ahead of you. As also noted in the manual, what you get from the meter is data that represents the on/off state of each segment of the LCD display. Not a trivial task to interpret that information. If you have a meter with better communication protocol, I would advise you to use it instead.
