Power up the NixChron and the 6 digits will display the firmware rev. The Globalsat does not need configuration assuming you have one of the later NixiChron firmware revs. I believe the 05’ revision and higher accommodates non-1PPS GPS pucks like the GlobalSat and later Haicoms. I know for certain the 11-02-10 not only includes the 1PPS change, but also was the first to address the DST issue which was a pain. If you do have the earlier rev. I believe there are still GPS pucks available with a 1PPS out. I would ask the group for a little help there?
