serial communications jibberish??

[IERengg]

I am trying to read from a device that out puts core body temperature and heart rate.  When I use hyperterminal the data displays as it should but when I try to read with lvterm.vi it looks like jibberish.

This is what it should look like.

I am not sure what is going on any help is appreciated.

Thanks,

IERengg

Have you verified the serial port settings? The type of errors you are seeing is common when the port settings differ, i.e. one side is set to 9600 and the other is 4800.

I have verified the serial port settings and unless there is an error in how the lvterm.vi inputs the settings, they should be correct.

4800 baud

8 bit

no parity

1 stop bit

no flow control

Thanks for the suggestion, if there are any other ideas keep them coming.

Have you tried communication through Hyperterminal?
If so, do you get the same jibberish or the correct results?

Edit: Nevermind, I just saw your screenshot was from Hyperterminal. Let me keep thinking then...

I appologize the first suggestion was the correct answer.  I did not hit the change settings button when running the vi.  After I did all is well, thank you for the fast responses and my ignorance.

No problem. As I mentioned the type of garbage you were seeing isalmost always the result of a mismatch in port settings. Glad thisresolved your problem.
