I have one doing that very job with a 5501. I use the $GPRMC sentence and turned of the rest. ISTR that was the sentnece recommended by the ntp.org s/w. If you'd rather not mess around with getting power from pin 10, and aren't otherwise using your USB connector, it is a +5V source, with enough hampsters for the LVC, at least with no internal HDD. Cutting up a spare USB cable is probably the easiest way to get connected there. This also lets you use a standard 2x5 to DE-9 cable for COM2:. Of course if you're putting a 2x5 header on the LVC cable anyway, never mind. If you haven't purchased the GPS 18 LVC yet, I seem to recall you could get it with two different length cables. I have 5m and I think the other option was 3m. -Jed _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
