Hello guys! I'm newbie here so please don't shoot at me. One month ago I bought GPS Evaluation Board - ET312 but I couldn't make it working with PC via USB cable. Sure that power switch is ON and port switch is on USB. As a software I'm using Mini GPS and GPSTrace under Windows XP. Maybe I need some drivers or special port configuration?
Thanks in advance for your help.

Have you grabbed and installed the latest (2.04.14) Virtual COM Port Driver from FTDI?

Thank you FartingMonkey92! Now with installed FTDI's driver I could see some data on terminal view of GPS Locator Utilities but fix is not available. Maybe it works only with external antenna? And what does mean switch "int/ext"?

The "int/ext" switch is for , i believe, switching the data lines between the two serial ports or
between the internal of external GPS modules... Not too sure!

If you are having problems getting a fix, it's probably to do with the building you're in...
Many buildings shield GPS signals quite well, so all i can suggest is take it outside and try again...
Oh and yes, you need an external antenna...
