Cannot use pins 2 - 9 as inputs, only outputs.

You should take via extra cable the 5 Volts NOT 12 Volt from PC power supply.

And use resistors, ca 5K between ground and signal.

My inputs react fast, your delay might be eplainable as you have nit realy clear signals....
An output of the printercard will not give a nuce source of supply.

I soldered a wire from the card to an additional connector, with i fixed on the card.

Good info, thanks. I'll look at getting it some cleaner power. I'm just happy now that I've got SOMETHING to work on. The frustration was overwhelming. lol.

Thanks again.

Hello Folks,

after hours of searching for exactly the same problem i stranded here...
My parallelport just ignores IN/OUT from Hal and any BIOS setting.
In Bios I have: ECP, EPP, Dual, OUT-Only.

Doesnt matter, what kombination i try; the port is allways in "OUT" mode.

Is it possible, that a port cannot be switched and the Bios stuff is a placebo=


Greetings Emanresu

I've never actually used a BOB but I understand some of them have fixed pins for Inputs and Outputs that can't be changed..

Hello rodw.

I dont use a BOB. Im talking about the parport itselfe.

I think its the same but its been 30 years since I made my own BOB and controlled it by writing to the parallel port. (non CNC application)
