I have the green and black wires tied together and going to a ground pin on the input pin header.

so I have the opb917bz specs
Forward Voltage = 1.3
Forward DC Current = 50mA
BOB put off 5.6V

the online resistor calculator say to use a  100000 ohm resistor for the power red+
did this with no results on a new switch

http://led.linear1.org/1led.wiz

I added in a 10k resistor from the 5v source to the input pin of the switch (blue wire). still nothing?

5v to the red wire reads 1.06v after the resistor going to the led now.

I wired up a new one with the 220 ohm resister and it did not work.
I thought some where I read that the input pin 5v supply is already limited to something small?
if I have 5v then what resister size do I want to use?
thanks

I have 043.066 for the version and was thinking about trying v3.042.033  if I can find a download for that. seems to be liked well for threading.

for the life of me i cant get the opb917bz switch working in mach.
i thought the one that worked forever died when upgrading my computer so i bought 4 more!

i have the c11g BOB and are trying to use the 5v on the input pins to run the red+ and white wires. i ran a 220 ohm on the red and once without. no difference. i cant find any ma output on the 5v pins.
the black and green are tied together and grounded on the grd of the input pins.
the blue goes right into pin 11.

the old computer worked fine with this setup for a long time but now i cant get any input on this.
if there is close to the right amount of power to the led should i be able to see it with my eyes?

so if the plug comes back and says  "configuration ok", what does that cross off the list as far as this not working?

vfd seems to be good.
plugin seems happy
what mach settings should I be playing with?
thanks
