7. Signed Mode - Likewise, any signal over 1 bit could be either unsigned or signed. Signed signals have their highest bit as 1 for negative numbers and 0 for positive numbers. You can search for only unsigned signals, only signed, or try it both ways. There really isn't any rhyme or reason for when a signal would be signed or unsigned. It could easily be both ways so unless you're sure it's probably safest to allow the program to try it both ways and you can pick which looks best.
Once you've got it all set up click "Recalculate Candidate Signals." Be prepared to wait depending on what options you selected. Once it is done processing you'll get a list of candidates in the upper list labeled "Candidate Signals." Here you can see all of the signals it found. You get the ID, the starting bit (remember, bits start at 0 and go through 63), the length, and whether it was signed/unsigned and big/little endian. If you click on or otherwise select a signal in this list then a graphical view of it will appear in the graphing area beneath. You might try the arrow keys Up and Down to move through the list. You can even hold down the arrow key and let it rapidly scroll. As it scrolls through the signals you can look at the graph and stop when you see a signal that catches your eye. This is useful as you can have hundreds of candidates and it is tedious to view them explicitly one at a time.
This window is handy for quickly finding signals if you know what the shape should be. For instance, vehicle speed is pretty easy to recognize. You can't go from 0 to 100 in an instant so speed tends to have a lot of sweeping motions up and down. Thus, being able to quickly see the signals makes it easy to find things that look like they "could" be speed. It might be vehicle speed in km/h, it might be mph, it could be wheel RPM. But, being able to see the graphs at a glance helps to narrow down the possibilities.
