WIFI Introduction
The Omnixie can connect to routers via WIFI and access NTP time servers to get
accurate network time (NTP servers are located all over the world and choose the
fastest connected server based on your location). Additionally, a phone or computer
can use the same WIFI connection to set all features of the Omnixie.
⚫ For the first connection, about 10 seconds
after the Omnixie is powered on, the WIFI
status indicator will light up in red to
indicate that the Omnixie WIFI is not
connected to any network and is waiting for
configuration. At this point you can use any
of the following methods to connect and
configure the WIFI network.

13 / 52
⚫ The Omnixie needs to be set to use your home network and requires a “one time”
setup.
⚫ On first power-up, the clock creates a WiFi hotspot for the initial configuration.
⚫ On your phone or PC: Go to the WiFi settings and look for an SSID like:
NCHxxxxxx. This is your Omnixie clock.
⚫ Temporarily connect to the clock WiFi SSID and a configuration window should
open, or simply browse to http://192.168.4.1
⚫ Teach your Omnixie to connect and use your own WiFi network by selecting your
home SSID and providing the network password.
⚫ When completed, the Omnixie will reboot and automatically connect to your WiFi.
⚫ Your phone or PC will automatically reconnect back to your home network.
⚫ Omnixie configuration will now use your WiFi network. Use your phone or PC
browser to view your Omnixie for complete clock configuration information.
Detailed steps for Android, iOS and Windows PC follow.

Setup the Omnixie using the Omnixie Dashboard
◼ Nixie tubes have an unwanted side effect called ‘cathode poisoning’ (CP) which causes
metal molecules from the glowing cathodes (digits) and attach to non-glowing cathodes. This
will cause deterioration and finally failure of the tube. To avoid this effect, non/seldom glowing
cathodes need to be periodically switched on. Since cathode poisoning varies between
different types of tubes, there is an adjustable cathode poisoning prevention setting.
◼ The cathode poisoning prevention function default settings are to run every 10 minutes
for 5 seconds duration. The switch on of the non-glowing digits will be achieved by a fast
sequential scrolling through the digits (slot machine effect). This feature can be adjusted in
duration and frequency of scrolling.

35 / 52
Upgrade Firmware
The Omnixie firmware can be upgraded via browser.
Setup the Omnixie using the Omnixie Dashboard
◼ Do NOT access the Dashboard page during the upgrade process, do NOT
power off, the Omnixie will automatically restart after the upgrade is
completed.
◼ Wifi network parameters need to reconfigure after upgrading.
Upgrade steps:
1. Click the Choose File button to select the upgrade file, make sure the
file is the Bin file used for upgrade.
2. Clock the Upload button to start the upgrade and wait patiently for
complete.

Special Remarks
⚫ These Nixie Tubes were produced between 1960 to 1980, and there may be some
differences between tubes and manufacturing lots. This is normal, and will not
have any effect on the tube operation.
⚫ The Omnixie will become warm or little hot during operation due to the internal
DC-DC converter circuitry. This is normal operation and no cause for concern.
⚫ The bottom plate of the Omnixie is made from stainless steel and is heavy. Please
take care not to drag the unit by the Micro-USB cable to avoid damage to the
Micro-USB socket.
