Missing Text

[IanR]

Hi All

I am using Labview 8.5 to read RS232 data from a unit under test as it boots up. The labview vi reads all the data I'm expecting as follows:

"****

CPB FPGA Functional Image Programmed Okay!
MCS BOOTLOADER Version 1.3.0 (RevB HW)

"

However when I call this vi from TestStand 4.0 and try to put the text into a local variable only the first half of the text is appearing. Everything from 'Firmware version...' is deleted.

I'm not sure if this is a control character problem, a font mismatch between Labview and TestStand or whatever.

Please could someone advice a way forward with this.

Best Regards

Ian

Sorted.... Just used the labview 'string to byte' function, filtered out all numbers less than 32 (control stuff in ascii table) then used labview 'byte to string' function. Now I have one long string and no control characters. Easy - Peasy!

Whenever you pass a string from LabVIEW into TestStand, you have the choice of interpreting it as a "binary string".  You'll find this option in the Module pane.  You will need to use this if you have important data (such as encoded information) that contains null characters (binary value 0x00; i.e. end of a string).
