What are the differences between RS-232C serial and USB versions of the AutoScope2?
The limiting factor in evaluating your vehicle is the vehicle buss. So using one serial connection (USB or RS232) over the other will not be faster. It depends on you PC which connection you want to use. The advantages of RS232 is it can have cable lengths up to 100ft; whereas, USB can’t without powered repeaters. To get around this limitation Anzen Electronics is designing a wireless version.
