Hy guys !
I have recently started a nixie clock project and now im trying around with the drivers. I have got some original K155ID1 Drivers (used) and I now have problems with them. According to the truth table (http://tubehobby.com/datasheets/k155id1.pdf) to get Pin 0 on, a b c and d should be Low. So I connect all the 4 pins to Ground and tested it out. Pin 0 is on, but all the other Pins are also, so my IN-14 lights up all 10 numbers, instead of only one. I have also tried it with Pins 2 or 3. The result stays the same, all the ouput pins of the K155ID1 go to high, making all the numbers in my nixie light. I have tried now several drivers and serveral nixies, but no difference. Anyone can help me ?
Note: Im using 180v for the nixies and a 10k resistor on the anode. The K155ID1 is connected to 5V (from arduino).
