NMEA Convert RMC to ZDA?
My GPS puts out RMC -- but I have a device that needs ZDA to get the time/date
-- RMC contains time/date -- is there any way (ie: any device) that can convert between the two? -josh |

There shouldn't be any problem as long as it's wired correctly. RMC is the recommended minimum data stream for NEMA data and ZDA is just time and date. The expectation is that the units will ignore most of the RMC data stream and only pick off what it is capable of handling - which in this case would be time and date only (ZDA). I think that's how it works. Unless you have some sort of proprietary equipment that uses a hinky system. Here's a link that may help you out. http://www.gpsinformation.org/dale/nmea.htm#intro |

I think that's how it works. Unless you have some sort of proprietary
equipment that uses a hinky system. Doesn't appear to be the case -- For example: Furuno device (navtex) accepts zda but doesn't even look at RMC... Here's a link that may help you out. http://www.gpsinformation.org/dale/nmea.htm#intro Just puled up a host-search engine thing.... |

Hmmmmm - Well, nothing for it then - I must consult the High Holy Book of NEMA Data Sentences... TO THE WAVE CAVE!!! Ok, the ZDA sentence: $GPZDA,hhmmss.ss,dd,mm,yyyy,xx,yy*CC hhmmss = HrMinSec(UTC) dd,mm,yyy = Day,Month,Year xx = local zone hours -13..13 yy = local zone minutes 0..59 *CC = checksum The RMC sentence: No need to go further - I see what the problem is. Hmmmm.... Are you by any chance taking the data and displaying it on a PDA or analog device? Here's a link that may help you out. http://www.gpsinformation.org/dale/nmea.htm#intro Just puled up a host-search engine thing.... Um...huh? |

Well, I'll be honest with you - the only thing I know about Furuno Naxtex is their receiver - I've never worked with Furuno data streams. I do know that on the Raymarine C system which I had on my Contenders, ZDA can be selected for date/time input (I just looked it up in the manual). I will readily admit that I'm not the brightest guy in the world, but I don't know what you are trying to do so I'd only be guessing - I'm completely in the dark. Sorry. http://www.gpsinformation.org/dale/nmea.htm#intro Just puled up a host-search engine thing.... Um...huh? http://jassing.com/temp/nmea.jpg Works fine for me - I just cleared my history, cookies and retried it - it's there. |
