  • Page 3 1. INTRODUCTION About the clock Nixie clock type ‘Halo’ is a compact design with all components and tubes mounted on a single PCB. The efficient use of board space is achieved by using a multiplex design to drive the display tubes. Two high-voltage binary-to-decimal decoder ICs (K155ID1) are required, driving the six tubes in groups of three.
  • Page 4 SAFETY DANGER: The clock pcb includes a switched-mode voltage booster circuit. This generates nominally 170 Volts DC, but is capable of generating up to 300 Volts before adjustment. Assembly may only be undertaken by individuals who are suitably qualified and experienced in electronics assembly, and are familiar with safe procedures for working with high voltages.

  • Page 5: Tools And Equipment Required

    2. TOOLS AND EQUIPMENT REQUIRED Tools required to assemble the PCB. The following tools will be required to assemble the PCB: Soldering iron with a small tip (1-2 mm) Wire cutters (TIP: A small pair of nail clippers works very well for this function) Wire strippers (TIP: A small pair of scissors is quite suitable) Multimeter for voltage tests and for identifying the resistors.

  • Page 10 ASSEMBLY OF THE PCB NOTE THAT THESE INSTRUCTIONS ARE SHARED BETWEEN SEVERAL VERY SIMILAR CLOCK TYPES. YOUR PCB MAY NOT LOOK EXACTLY LIKE THE ONE PICTURED. 1mm Sockets For Nixie Tubes (ZM1020 / Z560M / GN-4 PCB) There are 66 individual sockets that need to be placed. Note that there are 2 holes per tube with NO SOCKET.
  • Page 11 1mm Sockets For Nixie Tubes (IN-4 PCB) There are 66 individual sockets that need to be placed. Note that there are 3 holes per tube with NO SOCKET. Place each socket loosely as shown below: Be sure to insert the sockets FROM the tube side of the PCB – the side with the tube markings.
  • Page 12 Low Voltage Power components: J1, FUSE D1, D2 - 1N5819 IC1 - 7805 C1, C2 - 100nF Start by installing D1 and D2. Align the white band on the components with the band marked on the PCB. Proceed to mount the other components of this step. IC1 can be bent over to lower the profile of the board, but do not let it actually touch the PCB.
  • Page 13 Testing Stage 1 Power Components. Identify the test GND, 5V and 170V test points as shown below. Plug in the power supply, and then test using a DC voltmeter: Touch the black probe on the GND test point and the red probe on the 5V test point. The voltage should measure between 4.9 and 5.1 Volts.

The capacitors in your kit may be blue, brown, or possibly another colour. Look at the part markings, not the colour. 4.11 Tube Test At this stage, it is desirable and possible to test that the tube drivers and micro-controller are functioning correctly.

  • Page 18 4.13 AM, PM Colon Neon Lamps The 2 neons' leads need to be bent as shown below. Use small lengths of the clear insulation supplied on the leads to prevent shorts. Note that the neons are mounted nearer to the bottom edge of the PCB, which is the edge where the switches and power socket are.
  • Page 19 4.14 Microcontroller Tube Selection The Microcontroller IC3 needs to be setup for your PCB type as the tube connections differ for the 2 types of PCB (ZM1020 / Z560M or IN-4). The controller is by default set to the ZM1020/ Z560M configuration. If you are using this PCB then omit this following step.

  • Page 21 Now identify the cathode mark on the LEDs. This is usually a green marking at one end of the LED, though it may be under the LED lens and harder to see, It may also be an arrow or a line pointing in one direction on the underside of the LED: With a fine soldering iron tip, melt a small amount of solder onto the three cathode pads of the PCB at a single tube location:...

All settings are stored to non- volatile memory. You can set a brightness of 0 to 9 for each hour of the day. Entering LED menu Press and hold the ‘ALARM’...
  • Page 28 8. USING A RADIO FREQUENCY TIME RECEIVER OR GPS RECEIVER The clock can automatically synchronise time from DCF (Europe) and MSF (UK) long wave time transmitters. The clock can also receive time from a GPS receiver that transmits information using NMEA-0183 protocol, using the $GPRMC sentence. Configuring for RFT or GPS Synchronisation.
  • Page 29 Connecting a Radio Time receiver The clock has been designed for, and tested with our Radio Frequency Time (RFT) Receiver Modules. (available separately from PV Electronics). DCF Module: For receiving time signals from transmitter at Frankfurt, Germany. Reception is possible within a 2000Km radius of Frankfurt.
  • Page 30 Setting Up for First Reception. 1. Ensure the correct setting has been applied to Config 12: 1 = DCF 3 = MSF 2. For the first tests, ensure Config 25 is set to value 1, to make the HV converter switch off for synchronisation. This stops any noise created by the HV converter.
  • Page 31 Connecting a GPS receiver The clock accepts input directly from our GPS Sync Time Receiver Module: Please see the separate data sheet for the GPS receiver to find out the baud rate of your module, as different baud rates are used depending upon the version number.
  • Page 32 Function of the GPS / RFT indicator LED (D4):  No Radio Synchronisation source installed (parameter (12) = 0) LED is permanently off  RFT or GPS Synchronisation enabled (parameter (12) = 1-4) The LED will be ON if the clock has synchronised in the last two hours; slowly flashing if the last synchronisation was between 2 hours and 24 hours ago;...
