GPS to PC or MAC

This will outline the basics for connecting most GPS receivers to a PC or MAC serial connector for data transfer. Since the GPS needs to both send and receive from your PC or MAC, the data connection will consist in three wires:

  • Transmit Data (TxD)
  • Receive Data (RxD)
  • Signal Ground (SG) - (is common for both power and data grounding)

For GPS connector pinouts refer to documentation on Pinouts->Connector section of this site.
