You would tie the decimal point to a positive supply (like the other segments) thru a larger resistor. I would start with a resistor value 10x higher than the series resistor on the segments. To prevent wearout, use the lowest current that gives acceptable illumination.
I didn't see anything in the IV-22 datasheet specific to the decimal-point current, but based on surface-area it should be proportionately lower than the segment current. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
