hexcode on serial

[Mikael]

I have a problem with serial communication. I want to put hexcode directly onto the comport (RS232C), but VISA just converts my input to ASCII code. So instead of writing 0Ah (10 decimal) it writes the ASCII equivalent to 0 and A = 30 41. Is there a way to force it to send the original hexcode of 0A directly onto the comport?

Right click on your string control (or string constant on the block diagram).
Change from 'Normal' display to 'Hex' display.
Now when you type in 0A, it will be one byte (0Ah).

Use the CR and LF constants in the string function palette to send line terminators.
If you have other control characters, you may also use the Byte Array to String function.

Thank you, the hexcode entered directly into the string control worked fine. But when I have hex strings concatenated into one string and then into the string control it converts it to ascii hexcode. I need it to keep the hexvalues. Please see attached program code (LV 7.1.1).

I am grateful for som pointers on how to solve this situation.

You are formatting your numbers to hex format. Instead, you need to typecast your numbers to a string.

Try this (LabVIEW 7.1)
