To power the lamps:
Pin 12 needs to powered with a CLOCK signal for the High Voltage transformer. Don't know the exact frequency (can someone measure, please?). Works for me with 20KHz.
Sequence to power the Deuterium: Set high voltage to about 25% (4V), LED NO/F lights up. Then turn "D2 Fil" up until NO/F light goes off, ignition flash, D/OK should light green. Then turn D2 Fil down to zero again.
