How to use the ascii code in my VI

[飘零]

I have a hardware which could't communicate with ascii code , so as I recive the data from the hardware , the data is just a hexadecimal number , but LabVIEW will automatically transform it to a character , now I want to use the original data , how can I solve the problem?

Thanks a lot!

Hi, I supposed that you are using VISA Read/ Write functions for communication between your PC and HW.

VISA Read/ Write takes in command/ outputing result in string format. In default condition, String control/ indicator is showing ASCII data. In order to obtain it correspoding hexadecimal values, you may...

a. Simply right-click the String control/ indicator, and select "Hex Display" property.

b. Use "String to Byte Array" to convert the received String to Numerical data.
