advanced serial read write does not work

[sandramh]

I have a set of weighing scales that have an RS232 connection, sending a 'w' to

them over RS232 should result in the current weighed value being returned.

I have got this to work using Hyperterminal setting up the correct data values and

using XonXoff.

So I tried the 'Advanced Serial Write and Read.vi' example, but I cannot get it

to work. I set all the data the same as for hyperterminal, but nothing gets

read and the vi times out after 10000ms.

If anyone can help, I would be grateful,

regards,

Sandra

You may not be setting the correct termination character. The default setting is a LF (x0A). In Hperterminal, you send both a CR and LF. Make sure that the "End write with termination character" is set to True and try changing the termination character to x0D or both (xDA). By default, the read is terminated with the same ternimation character so you want ot make sure that it is the same. Check the instrument's manual.
