send text file via serial

[Tokyghy]

hi

i've trying to send a text file via rs-232 but no success

The file contains a code for a device im dealing with, when i send the text file with labview to the device, it went ok with no errors, but when i connect the device on hyperterminal and check if the code was loaded it was not.

can you please give some clues to deal with this?

thanks a lot

attached example text file and LV code

It looks like you are reading the entire file at once so the loop is pointless. You may in fact need to write a line at a time with each line terminated correctly or each command. In either case, you want to read the file once and create a string array that is indexed by s for loop.

Some devices are very picky with the End Of Line.  You might want to right-click on your FIle Read and deselect the "Convert EOL".

Or if you need to write 1 line at a time, right click on the Read Text File and select "Read Lines".  Set the number of line to read to -1 (read all) and then wire the resulting array into a FOR loop where you do the VISA Write.

Thanks for your replies

it seems the for loop thing worked

thanks for helping
