3. Overview
4. Model and Version Identification
The NIX labs filament clock range includes the FL4 model at time of printing. The device’s product and version
information can be found when using the web app by selecting the gear icon in the upper right and selecting
Diagnostics from the menu. The circuit board is marked with the product’s model (eg: FL4) and major hardware
revision (eg: Rev A) near the USB socket.
5. Powering Up
Check the box for the following items and remove them from their packaging:
•FL4 filament clock
•Australian power adaptor (or Multi-Region adaptor for international orders)
•Quick-start guide
For international orders supplied with the multi-region power adaptor, remove the AU plug from the power
adaptor, and replace with the correct one for your region (US, EU or UK).
Plug the power adaptor’s USB-C end into the socket on the back of your clock either way around. Connect the
power adaptor to the wall outlet and turn on - your clock will show 88:88 for a few seconds after which it is ready

5.1 Other Power Sources
Your NIX labs device is powered by a standard USB-C connector, just like many mobile phones, cameras and other
computer accessories. This means it can be powered from a number of sources such as computers, power banks
and common USB chargers. The supplied voltage is important in ensuring maximum display brightness and should
be as close to 4.9V to 5.1V as possible –using low quality USB cables and chargers is not recommended. The power
supply included features a robust construction, high output capability and all the required regulatory safety
approvals. For this reason, only operation with the supplied adaptor is recommended and warranted.
If using a power adaptor other than the NIX labs recommended unit, ensure it has a 5.0-5.1V output rated for at
least 1A. Ensure any substitute power adaptor carries the compliance markings for your country, for example, the
Australian RCM ( ) and/or safety approvals such as the UL mark ( ). Do not use generic adaptors from eBay or
similar, as poor quality units can be a fire and shock hazard, and could damage you or your clock.
When powering from a computer, connect directly to the computer’s USB port – avoid unpowered hubs or
extension cables. You can use any good-quality charge & data USB-C to regular USB-A or USB-C to USB-C cable to
connect your clock to your computer or phone/tablet.
The display brightness will adjust automatically according to the power output of the adaptor (or PC) used. If the
display seems dim, despite being set to full brightness, or in the case of a flickering/flashing display, ensure the
supplied adaptor is used. It is also possible to read the voltage using the web app’s diagnostics screen – the
acceptable range is 4.7V to 5.3V.
6. Reading the Display
The back-side of the display has RGB back-lighting, which can be set to show a different colour based on the current
“screen” (Time, Date or Temperature). The FL4 displays hours and minutes in a “digital” seven segment format,
with one colon in between. Do not press on the LED filaments as they are not flexible and could be cracked from
mishandling. The following section describes how to read the display in each of the Time, Date and Temperature
modes.
6.1.1 Time Display
The FL4 shows time in an HH:MM format, which can be in 12 or 24-hour with or without a leading zero for hours
less than 10. In this time screen, the colon separator can be set as solid on, solid off, fast flashing (0.5Hz) or slow
flashing (1Hz). In the example below, the time is 12:47.

NIX4 and NIX6 User’s Guide
Filament Clock User’s Guide
5
6.1.2 Date Display
The FL4 can show the date in a DD.MM or MM.DD format. In this date screen, the lower colon separator is lit to
distinguish between the day and month. In the example below, the format has been set to DD.MM and so it is the
23rd of September (23/09).
6.1.3 Temperature Display
The FL4 shows temperature in a XX.X format in either °C or °F, with a displayed range of 0.0°C to 65.5°C (or
equivalent in °F). In this temperature screen, the display is left-aligned and the lower colon separator is shown as a
decimal point. In the example below, the temperature is 25.6°C.

7. Using the Built-In Buttons
Many parameters can be set using the three built-in buttons, so connection to the Web App for configuration is not
required. When on the home screen, briefly pressing the ▲button displays the date, and then temperature for a
few seconds. If the date is not set (which can be done using the Web App) then only the temperature will be shown.
Also on the home screen, briefly pressing the ▼ button cycles through the LED backlighting colour options. Using
the Web App allows individual setting of the time, date and temperature screen backlighting colours –if they are
set individually, then pressing the button only changes the time screen. If the colours are not set individually, or
LEDs-Off is selected, then the button setting applies to all screens. The built-in backlighting colours are as follows:
Red
Green
Blue
Cyan
Magenta
Yellow
White
Custom
Cycling
Off
7.1 Setting the Time
Press the SET button briefly and the display will be changed to only show the hour digits. Press the ▲ and ▼
buttons to set the hour and SET to advance to the minutes to do the same. After adjusting the minutes, pressing
SET again will save the new time and return to the normal time screen. When the new time is saved, the seconds
are set to zero. If the setting menu is entered into but the hour and minute values were not changed, then there
will be no change to the time (including seconds). If in the time setting mode and no button has been pressed for
30 seconds, the display will revert back to the normal time screen without saving.
7.2 Using the Counter/Timer
When your clock is showing the time, hold ▲for 3 seconds to start an up-counter. To start a countdown timer,
hold the ▼button on the time screen, and the display will change to showing just the timer hours. Press the ▲
and ▼buttons to set the hours, then press SET to advance to the minutes, and then SET again to start the timer.
The maximum counter/timer value is 99 hours and 59 minutes. If the up-counter reaches 99:59, it will be cancelled
automatically.
When a timer is running, the ▲ and ▼ buttons are disabled, briefly pressing SET will pause/resume, and holding
SET for 3 seconds will cancel the timer. Every minute the current time will be shown for about 3 seconds. If you set
a counter/timer, the display will stay on even if an on-off timer is set (USB sleep is not affected). A timer/counter
will continue running through sleep, however unplugging your clock will cancel it.

7.3 Parameters Settings Menu
Hold the SET button for 3 seconds and the displaywill enter the parameters settings menu, which allows adjustment
of the brightness, backlighting colour, 12/24hr time and other settings. The leftmost digit showsthe setting number,
and the rightmost digits show the current value –use the ▲and ▼ buttons to adjust. Press the SET button briefly
to advance to the next setting, and at the end of the settings list it will save all changes and return back to the
normal time screen. If no button has been pressed for 30 seconds, the display will revert back to the normal time
screen, saving any settings that were changed. The ordering and description of these options are shown below.

8. Online Configuration Application (Web App)
A key feature of your NIX labs clocks is ease of use, and as such, it is not necessary to connect your device to the PC
for operation, and many options can be set, if desired, using the three built-in buttons. The web-based configuration
application (“web app”) uses the WebUSB feature on Chromium-based browsers, such as Google Chrome,
Microsoft Edge or Opera, on Windows, Mac, Linux and Android, and does not require any additional software or
drivers to be installed. Linux users may need to add a udev rule with idVendor=04d8 and idProduct=eead.
To access the web app, simply connect the clock to your Windows PC or Android device, open Chrome, and visit
app.nixie.com.au, then click “Connect” and select your device from the popup list.
Below is a comparison of all the options that can be set using the buttons or web app.

8.1 Using the Web App
You can use any good-quality charge & data USB cable to connect your clock to your computer or phone/tablet.
The interface uses drivers already built into modern operating systems (Windows, Mac, Linux and Android) and the
WebUSB feature of Chromium version 61 and newer –no additional software is required.
When your clock is connected, use Google Chrome, Microsoft Edge or Opera Browser to visit app.nixie.com.au and
click on the Connect button at the top right of the page. A dialog will appear listing all of the compatible NIX labs
devices found - choose your device and click connect. Upon connection, all of the device’s settings are loaded from
the clock to the Web App. The Web App is arranged with tiles to group similar features, and the settings in each tile
can be saved to your clock by mousing over the tile and clicking the send button that appears at the top right. If
you adjust a setting using the device’s buttons whilst you are connected to the Web App, the page must be
refreshed in order to update the controls on the settings tiles.
Note: Because most computers have a slightly lower USB voltage than the supplied power adaptor, the higher-level
display brightness options may be dimmer compared to normal.
An overview of the Web App showing major buttons and features is included in the screen capture on the next
page.

9. Maximising the Light Sensor Accuracy
Your filament clock has backlighting LEDs that can be set to a colour of your choice and can give a great ambience
effect when the colour projects onto a wall behind the clock. If the backlighting LEDs are set to a high intensity,
and/or the surface behind your clock is fairly reflective, the LEDs may influence the light sensor which could limit
the effectiveness of the auto-brightness feature or may even prevent your clock from dimming during the night.
If this occurs, try moving your clock further away from the rear surface or reducing the LED intensity. You could also
change to time-based night dimming or re-setting the night-time light threshold.
10.Maximising Temperature Accuracy
NIX labs products feature sophisticated digital compensation to maximise clock accuracy over a wide operating
temperature range. For best compensation performance, the temperature sensor is located inside the case.
Although this gives the best clock accuracy, the temperature readout feature uses a correction algorithm so that
the temperature displayed to you is as close as possible to the ambient air temperature, rather than the
temperature inside the case (which is usually about 2-3°C warmer). This correction gives best accuracy when your
clock is located in free space, with relatively still air and after a 1-hour stabilisation time after turn-on or changing
display brightness.
11. Settings and Time Backup
All settings are saved permanently to memory, which has a storage time typically greater than 10 years. During a
power outage, the time and date continues to run off a supercapacitor, which has a run-time between 5 to 7 days.
Keeping your clock plugged into power and avoiding prolonged exposure to high temperatures will maximise the
supercapacitor’s life.

13. Firmware Upgrade
Your NIX labs clock can be upgraded to the latest firmware version in less than one minute using the online Web
App. Click the gear icon and select Firmware Update from the menu. From here you can see the changes and new
features in the latest version, and start the upgrade if desired. The display will turn off during the upgrade and a
single LED will be lit to show the status –this is referred to as Bootloader Mode (refer to below table). The time/date
and all of your settings are preserved during the update, which usually takes 30 seconds.
LED Colour
Meaning
Red
Device is in bootloader mode, but no PC is connected
Yellow
Device is in bootloader mode and connected to the PC
Purple
Firmware download in progress
Green
Upgrade completed (see note below)
Note: during a successful firmware upgrade, the green LED will flash only very briefly. If the green LED stays lit, but
the display does not light, then the firmware upgrade was corrupted. In this case, follow the steps below to
manually enter the bootloader and try the firmware upgrade again.
If the firmware has become corrupt or behaviour is erratic, you can manually enter the bootloader and still connect
to the Web App to do a firmware upgrade. To do this, unplug the clock then hold down all three buttons whilst
plugging back in. A single LED should now be shown according to the table above. To exit the bootloader mode,
simply disconnect then reconnect the USB cable.

14. Cleaning and Maintenance
If your device become dusty, unplug it and wipe with a clean, lightly dampened cloth. Do not use solvents on the
case as they may cause damage. If insects or dust gets into your clock, unplug it and use a can of compressed air /
air duster (available at computer stores) to blow out the material via the gaps around the base. Never insert objects
into the gap in the enclosure as this could damage components or cause a short-circuit. Take care when handling
since the LED filaments are not flexible and may break if bent or pressed on.
There are no single-use fuses on the circuit board, nor any batteries. There are not any hazardous voltages present
within the product. Apart from general cleaning, no maintenance or periodic servicing is required.
