Software USB Powered Nixie Clocks
Firmware Version 1.3
Notes
1.
Master Blanking Mode has priority over the Night Mode. Use this mode to disable all displays on weekends
(e.g. the clock is in the office) or during weekdays (e.g. the clock is at home). Master Blanking shuts down HV
supply and LEDs to save power and tube life. Briefly pushing SET will turn on the display for the time span as
setup in option 28.
2.
Night time column LED mode is active when night mode is set to dim. During night time blanking both, Nixie
display and column LEDs are disabled.
3.
The clock is fully functional without DCF / WWVB / MSF or GPS synchronisation. Set the time manually.
4.
Enter you time zone offset depending on your location. Note that WWVB transmits UTC. This correction just
takes place when the next time frame is received; even on GPS.
5.
Set this to „1" to disable the auto DST correction on WWVB sync – e.g. Arizona does not observe DST. This
feature is only active in WWVB sync mode.
6.
Visual effect / cathode poisoning prevention. All digits on all tubes are cycled for 10 sec.
7.
DCF / WWVB / MSF sync takes place at the hour. If no valid frame is received in 6 minutes, the clock reverts
to normal operation. Pushing ADJ will cancel seeking.
8.
Date will be displayed each minute between seconds 50...55.
9.
Press SET during Night time / Master Blanking Mode will turn on the display.
10.
Set this parameter to "1" to restore original factory settings. After restoring, this value is set to "0"
automatically. Alternatively the defaults can be restored by keeping SET pushed during powering up the clock
(cold start) with fully discharged Super Capacitor.
Rapid DST Adjustment
Press DST briefly to toggle between DST and standard time. The yellow LED indicator shows whether DST mode is active
or not. If the time has been synchronized from DCF, WWVB or MSF source, the light (and DST mode) will be set or
cleared automatically. It can be manually overridden, however the clock will re-set the DST status again at the next sync.
Note, that GPS time data does not contain DST information, so that the DST status will need to be set manually in GPS
sync mode as well as in manual time set mode without RTF receiver.
Radio Frequency Time or GPS Receiver
The clock can automatically synchronise time from DCF (Europe), MSF (UK) and WWVB (US).
The clock can also receive time from a GPS receiver that transmits information using NMEA-0183 protocol with $GPRMC
sentence; e.g. the wired BR-355 or the wireless GPS connection.
1.
Set option 12 for: 1 = DCF, 2 = WWVB, 3 = MSF, 4 = GPS
• If using GPS, set the baud rate in option 13 (normally 4.8 kbps).
2.
Set option 14 and 15 for the hours and minutes your time zone on standard time (no DST) is offset from the
synchronization source. This are usually only a whole hours:
• Germany is 1 hour plus offset (non DST) from UTC time transmitted by the GPS.
• UK is 1 hour minus offset from the time transmitted by the German DCF signal.
• France has no offset from the time transmitted by the German DCF signal.
3.
Set option 16 to identify if your offset must be added or subtracted from the time source.
4.
If you're using WWVB source and you don't need require automatic DST adjustment, set option 17 to "1"
5.
Set option 23 to select between hourly seek and daily seek in DCF / WWVB / MSF modes. Daily seek is
recommended.
6.
If you have selected daily seek, use option 24 to set the time of the daily seek.
7.
Leave option 25 set to "1" to turn off the tubes during seek. This prevents interferences by the HV generator.
Set this option to "0" when using GPS source.
Function of the green SYNC indicator LED
No radio synchronisation source installed (option 12 = 0)
LED is permanently off
RTF or GPS synchronisation enabled (option 12 = 1...4):
The LED will be on if the clock has synchronized in the last two hours.
The LED will slowly flash if the last synchronization was between 2 and 24 hours before.
The LED will be off if the last synchronization is older than 24 hours.
Additional, if DCF / WWVB or MSF mode is selected, the LED will flash rapidly whilst the clock is actually
receiving and processing a valid time frame.
The function of this SYNC LED many be summarized in the table below
