Okay, I know I've seen it somewhere before on the internet, quite possibly Dimension Engineering's website, but I can't find any trace of it now.
I have a sabertooth 2x25 motor driver which I plan to connect to a PC's serial or USB Port. To do so, dimension engineering suggested a MAX232 type chip, but can't you use a USB to TTL converter cable too? For instance, this one?:http://www.superdroidrobots.com/product_info/USB_TTL_Cables.pdf
For instance, if I wanted to use simplified serial mode, don't you just connect the green wire to S1 on the Sabertooth (and then the black wire to the 0V on the sabertooth, do I have that right?).
Thanks in advance!
