2907Re: [tracker2] Serial Port
- Feb 7, 2008The Garmin GPSMAP 60c has both a serial connector and a USB connector on the back, you can plug the serial cable into the back of the Tracker2 and feed it NMEA 0183 data at 4800 baud for example. I had hoped that I could then plug the USB cable into the GPS and computer and then use the Garmin USB protocol with a mapping program such as USAPhotomaps, but as soon as the gps detects that you have plugged in the USB cable it shuts off the serial connector to your Tracker2.

Your hope that the USB and RS-232 port can be used
separately at the same time presume they are separate
ports. It is not uncommon to implement a USB port
using a USB converter IC, such as FTDI's FT232 or
Prolific's PL-2303HX. In such a case, it's almost
necessary to disable the unused port to avoid bus
contention issues. So, hardware limitations may
hinder what you propose, but I don't know if that's
the case with Garmin's hardware.
