Conclusion
A conclusion is the place where you got tired of thinking. - Harold Fricklestein
When you power up the GPS modified clock, with the GPS plugged into it, it will at
first appear and function as it did without the GPS. Set the time to within 15 minutes,
and let the clock run. When the GPS acquires the satellite signal, the time displayed
will correct itself, and stay locked onto the GPS PPS output from then on.
Additionally, every morning, at 2:45am local time, the clock will recheck that it has the
correct time according to the GPS unit.
If you connected the jumper wire to one of the nixie decimal places, it will light up to
indicate that the GPS has synchronization and is sending PPS signals If the GPS does
not acquire synchronization within five minutes, you may need to move the GPS
antenna to a location closer to a window, or away from obstructions.
I hope you enjoy your GPS upgrade. If you have trouble with the unit, please contact
me, Peter Jensen, at jensen@peterjjensen.com.
