this is how it is wired..
There are 4 pins on the sensor. Hook the out pin to the printer port
pin,
hook the 5volt to a 5v source, the common pin to the printer port
pin 25 as
well as the 0vdc line of the 5volt supply your using, and for the
LED, you
hook a resistor between L and 0vdc. The value determines how
sensitive it
is. I used a 200Ohm and it seems to work fine..
I have the index-pulse ticked and the timing-pulse ticked in
the "input signals". and assigned both to pin 15.
What else do I need to do?
