Serial to USB cable?
I have a serial cable for my Garmin Etrex, one side a serial plug the other goes to my GPSR. I am about to get rid of my desktop and only use my laptops but I don't have a serial port on either. Knowing this the serial cable is useless unless I spend another $40 - $50 on a "Serial to USB Converter". So, I cut it to see what and how many wires are inside of it and found only three. I was thinking of making my own cable but I don't understand the difference between the two ports. I saw the GPS 'ible
here and it's no help unless you don't have the serial cable already...
Here are my questions:
1. As long as I connect the proper data in, data out and ground to the USB cable shouldn't it work?
2. Are serial ports and USB ports that much different?
I read a lot on the pfrancs
website and i noticed a few of the connectors looked like they may have had USB cables hooked to them. I've searched and searched but came up with squat! If you have a really good understanding about USB and serial ports can you please help me or direct me to someone who can? Thanks in advance!
