[Emc-users] Interface with the parallel port

[Farzin K. <far...@gm...>]

Hello guys,
  I have a question regarding an output signal on the parallel port. I need
to know how I can interface an output signal on the parport with for
instance a signal on a drive for spindle.
For example I have a 0 and five volt signal on pin-2-out and I want to use
it to turn spindle clockwise on its drive (inverter). I do not want to mix
parport signals with the drive signals.
I think I need some kind of relay (probably an electronic one) to energize
it with the parport signal and use its contacts for the spindle drive to
turn it on and run it clockwise, etc.
Thanks
Farzin
