In the past couple of days, I have been having some problems with matching the COM (Communication Port) number on the Debug Terminal with the COM number on the Basic Plot Lite program. The Debug Terminal only gave me an option of COM 10, where Basic Plot Lite only gave me options of COM 1 to COM 4, therefore I could not get the program to plot my data that I have collected with a photoresister using a RC circuit.
So I upgraded the Basic Plot Lite program to see if the newer version gave me more COM options. Unfortunately, the new version only gave me option to COM 9.
After messing around with the settings in some hope that my options would be in a wider range, Mark (my brother) gave me this advice to simply change the USB port that I'm connecting the serial cable in. With exitement, after having to download all the programs on a different computer I finally managed to get COM 4, allowing me to now finally use the Basic Plot Lite program and visually see my data on a graph.

Good work Richard. Thats why its important to sometimes stop, take a step back and think about what you are doing. The reason why I thought of plugging it into a different USB port was beacuse when I saw the screen shot you sent me it became apparent that the COM number referred to to a port ID. What is a port? read about it here: http://en.wikipedia.org/wiki/Computer_port_(hardware) your USB cable plugs into a port and the data logger needs to know which port its reading from. It might have been the case that it could not read from certain ports, so by trying a different one - yuo found one that works! Can't wait to see the plots Rich.
