Is it possible to convert Hexadecimal to ASCII characters?

Asked By turner.susan 130 points N/A Posted on - 05/28/2011

Hello there,

As a new user of llabview website, I want to explore everything that goes with this one. I was trying to communicate with HH506R omega thermometer using serial port communication. Then, I decided to use the parameters (such as Parity, baud rate, sto bits) because it's written in  the manual. And luckily, I could write the data from the write string when it responded. But  unfortunately, while returning the data, a framing error showed up. Also, I am not getting the read string in terms of ASCII characters.

It's just a random character which I don't know how to convert into ASCII format. I am using the Basic serial write and read VI from NI. Is there any way to convert the hexadecimal into ASCII characters?

Hello Susan Turner!

• It is not a hard or critical task to convert the code (Hexadecimal to ASCII). You can run the C code on your computer using any software like turbo C . The conversion code is available in the internet. You can easily get it and convert your codes exactly the way you want.
• Of course, you will get some other conversion codes. There are manual ways to do this, and you will just have to get a table called Hexadecimal to ASCII code. Then, your problem will be resolved.

There is one important thing that you should keep in mind before you try to read your hexadecimal code. If you get random characters, it's a scrap signal, it will never work. Don't worry about what is printed out, you just have to verify your serial port configuration again.

• Your connections are very important here. Hexadecimal numbers are between 0 and F: 00 0A 15 23. This is an example of hexadecimal code. Strange random characters are spurious signals. You must also verify the “flow control” on your serial port.
• It must be turned off quite often.

Good Luck.
