Now that we have the tubes mounted, we can mount the separators. We do this after the tubes
are mounted because now we can judge the height that the separators should be.
Notes:
•
You can install either LEDs or neons as the colon indicators. There is a minor change to
the components depending on which you choose.
•
For LEDs
: You need to connect P1 “VIN” to “COM” and choose 1k values for R38 and
R39. You need to take care of the polarity of the LEDs, following what is marked on the
board.
•
For neons
: You need to connect “170V” to “COM” and choose 120k values for R38 and
R39. The polarity of the neons does not matter.
•
Be careful to adequately insulate the LED leads using some heat shrink or excess plastic
sleeving.
