Qstarz 818XT Question

I have a Qstarz 818XT, attached the GPS to my pc. And openen the QStarzGPSView program.

now i see a lot of settings. Is there a smart guy here that can tell me whats those settings mean?
The only thing i know is the "Fix update rate" the rest is magic for me.

The NMEA output settings is changeble from 0 till 5

This is how QstarzGPSview look like:

    The letter combinations are different GPS sentences. RaceChrono is using combination of GGA+RMC or alternatively RMC+ZDA+VTG for positioning and laptiming. GSV+GSA is used for the satellite info (rather nonimportant compared to first ones). The number in the fields mean how many times they are updated per second.

    Thnx aol for your quick answer.

    my RMC was 0. so no updates. I clicked on default settings and this was the result: http://i.imgur.com/JOpzer7.png


    But after 1 test with my phone, what works perfect now.
    The settings are changed to: http://i.imgur.com/pA0Essv.png

    What's the best setup to use my gps dongle with racechrono? The max rate of the 818XT is 10Hz, so i want to use 10 hz to get the best correct laptimes.


    Edit: When i pull the battery, the settings will go to default.

    Also RaceChrono will modify the settings unless you set the "Do not modify MTK" on RaceChrono device settings. I think these settings are what RaceChrono resets them to http://i.imgur.com/pA0Essv.png . I think those settings mean RMC + VTG are 10 Hz and GSV + GGA + ZDA are 2 Hz, which is fine for RaceChrono (see my first message).
