Preface
This manual provides instructions for performing firmware updates as
well as a brief firmware version summary for the MOD-SIX Nixie Clock
System.
Intended Audience
This manual is intended for all MOD-SIX Nixie Clock System owners.
Important Cautions
Hazardous voltages are present at some locations on the circuit boards
when the clock is operating. Avoid touching any components other than
the updating dongle while power is applied.
Never install or remove the updating dongle or the RF-Link mezzanine
board while power is applied.
Like all electronic devices, the clock system components can be damaged
by static electricity. When updating the firmware, always touch the
aluminum base plate first to discharge any static.
The tubes are extremely fragile and expensive. Take care to avoid
damaging them when removing and reinstalling the acrylic cover and
when updating the clock firmware.
