    Share GPS

    I’m trying to find a way to “split” a serial cable so that I can use a single GPS on two computers at the same time. The GPS I have is fully automatic meaning it needs no initialization in order to start sending NMEA sentences. Can I just split the Rx and the ground and run them to the two computers? I have seen some serial port debuggers that do just that.

    I don't see why not, just try it I would say. maybe first measure if you have a voltage difference between the two grounds. If there is, I would reconsider or run a thick cable between the computer chassis' before connecring the GPS

    just thinking....
    If at first you don't succeed.........
    destroy all evidence you tried

    for info on t6369c LCD or Presslab's powersupply check:

    I've had the Garmin 35 for about two years. I'm not sure why I didn't buy the Garmin 16, maybe it's relatively new? I haven't heard to much about it. I think I paid about $200 for the Garmin 35 back in the day.

    Funny you mention the splitting function.

    A friend of mine did just that sharing the Garmin GPS35 (actually the standalone guts with separate antenna...long story)

    Anyway, the GPS35 will put out two serials anyway, but the neat part is that since you don't need to talk to the Garmin...just receiver the data...you only have to split the data line.

    There may be some signal loss, but it is a one way transmission, like patching into cable tv.

    I would put the junction in a shielded box (metal) and use shielded cable runs from the splitter.

    the splitter is simply splicing all your items desiring gps feed together and hook to the data out.

    only use the one data line...not the clock or anything else.

    I don't remember if they had any problems...I'll ask.


    OK talked to them...it worked just fine.
