Hi guys

I need a breakoutboard for my second paralell port to make the buttons on my controlpanel connect to my computer.

Do I need a seperate BOB, or can I use the +5v on the other bob as long as i connect the grd´s, or is there a common ground in the pc that takes care of this?
Of course this would not be isolated in anyway, but can it be done?

I run a secondary paralellport driving 2 servos in step/dir, and a driver/bob for the stepper on the z axis.
This bob only have homing, limit/emergency input and 3 outputs.

Running my machine today wit just an old printercable stripped at the end and the wires connected directly, but as I understand I need a BOB to get my 5v from the specific paralell port , as i dont see any +5v on the paralell port pinout.

I guess the 5v on the other port/bob is transformed from the powersupply on the board, am I correct+

So need a tip of what BOB to get to make this good, easy fast and cheap....hmmmm possible?... dont know, but the fast part could be nice

Bring it on guys, what do you recomed for a BOB intended only for I/O

Live in Europe so if anyone have any suppliers ther it is also interesting

Best reg
