Hi Chrissara.
The software doesnt' come with the cable. The cable I had ran from serial (laptop) to RS-232 (meade). If you don't have a serial port on your laptop then I guess you'll need a usb/serial converter cable.
If you want to take the easy way out as I did, give the Bintel boys a ring. Yes you'll probably pay more for what is fairly standard equipment, but if you are like me and tend towards technology neanderthalism then they are a god send. (I must admit though I'm getting better
I'm at about homo erectus level atm)
