The SiRF Binary Protocol contains characters that both cannot be printed by your console and cannot be generated by your keyboard. I would advise to download some terminal program to send hexadecimal characters to the GPS module. The terminal program used for the following instructions is CoolTerm, and can be found here.
To switch to NMEA protocol:
- Open CoolTerm
- Adjust the COM settings accordingly, and open the port
- Open the "Send String..." window found in the "Connection" menu.
- Select Hex mode
- Paste the hex string found below into the textbox
- Press "Send"
- The "Send String..." window can now be closed. The GPS module should now report messages in the NMEA protocol.
