LPT2

Can the flood and mist outputs be triggered from LPT2?

I would think under the outputs tab I can use;   Output 1  port 2 pin 17

That look right?

 I have a cnc4pc c15 relay board that I want to use for my solenoids.

I want to eliminate using LTP1 which is a Gecko540

Yes no problem with that at all.

I checked parallel port 2 and I am getting 3.3vdc when I hit the flood.  Problem is the C15 is not triggering the solenoid.   I am not sure where I should be getting the ground from for the C15.  Should I be getting off the parallel port?  The wiring instructions say the grounds are common.  No clue what that means.

I did call CNC4PC and the possible problem could be the relay is optoisolated and it may not work with a parallel port.  Although it seems to say to me it should work with a parallel port.

The ground I would imagine would have to be from the same source as your signal, are you getting the signal direct from the port or is it via a BOB?

Directly from the parallel port.

Reading the docs it would seem to suggest it should work from a parallel port.

I was told I bought the wrong board.  I need the C36.

Their website seems to say the C15 only works with 5V parallel ports, while the C36 works with 3.3V and 5V ports.

But the docs mention 3.3v which would make you think its fine.

Thats what I thought.
