The checksum is a simple calculation that you can do with the help of Google:
Try this Web App: http://www.hhhh.org/wiml/proj/nmeaxor.html
BTW, I don't think appending the checksum is necessary. Try it without if you want, especially if your doing the setup manually.
i've just recently started prototyping with this gps unit, so thanks to everyone who has posted information.
just so others know, the default for my unit was 57600bps, 5hz output. I was able to lower the baud rate to 4800 only after I reduced the output to 1hz.
Does anyone know what the best setting for DGPS_Mode should be, or at least what it depends on? If RTCM, how does RTCM baud rate fit in? (or are they unrelated)
Also, I am a bit unsure of what "API_Set_Flash_User_Option" does. Is it used to set the default settings, so a reset to default using "$PMTK104*37" would reset to the settings I set with "API_Set_Flash_User_Option"
No public wish lists :(
