I apologize for the unhelpful title, but I'm not sure how to explain this. I have a list of "hex-like" values that are payloads captured from tcp packets between third party software and a lab device. The software sends commands to the device over TCP and those are the packets I have captured. Wireshark exports the data into "hex like" strings such as "59454d0d50" or "5851562c320d01" and I have saved them into a list. When I read this list into LabVIEW using "Read from Text File", I get strings in that same format e.g. "59454d0d50". The problem is that this string is not what I want to use. It's not interpreted as "hex" it's interpreted as an ascii string. However, if I copy and paste this value into the str control with "display as hex" enabled, the str is "parsed" correctly and I get the true value I am looking for, which is some weird ascii value (see the images). Is there some way to get LabVIEW to parse this without needing to copy and paste into a string control?

Just another version as suggested by @GerdW

Hi F34, welcome to the LabVIEW board! See this as suggestion:

LabVIEW

Convert hex-like string to hex or ascii

Solved!
