DB25 breakout board

Hi All,

I've set up an LTspice simulation. I've played around with a paralell capacitor. I also tried to alter the load resistor (1k) to improve the turn off time of the opto, but I could not get much improvment.

LTspice is free and available from www.linear.com


Cheers!

Hello !

Is there a way to use this board for input ? The pins 2-9 are my concern.

Thank you
Giorgos

Pretty sure the answer is no. (I don't have one.) But their are other inexpensive boards that can.

I think this documentation is for that board. P13 to P15 are inputs.

This document is buried on the forum here somewhere.

Its the best info I found but you can't alter the outputs to inputs.

Can you please point me in a direction for these inexpensive bob's ?
One or two link are appreciated!

Thank you !
