5i25 P2 Connector for logic level I/O was created by B.Reilly01
My 7i77 is located in one control cabinet, and the 5i25 in the control panel(with the PC). I'm planning out the control panel, and was wondering if I can breakout the P2 connector on the 5i25 for simple input/output buttons/lights for the control panel instead of running an umbilical into the 7i77 just to transmit it back along the DB25 cable. Am I correct in thinking that IO17-33 could be used as logic level I/O by just connecting a ribbon cable to the P2 connector and splitting it out? What can the outputs sink? If I want more buttons, can I just breakout a parallel port too?

Outputs can sink 24ma
If you have 5V referred loads (like LEDs) its best to use open drain mode
