Greetings,

I am working on a system which I’ve lost the original file created by FIR Designer. I can, however, obtain the coefficients from the equipment by parsing the “preset” file it creates once saved to the PC. I would like to bring this back into FIR Designer for modification where I’ll be working tomorrow. I’m unsure how to interact with the information I can parse. Below is the relevant text:
