shaneb24 WROTE:yes that is what i want. in steps I'm trying to go from ps2 controller then PSC28A then K8023S then K8023S then relays.
so the interfacing between the PSC28A then K8023S is where I'm have trouble.
So you'll be using this K8023 in pair and connect the control section to PSC28A?
In K8023 datasheet page 17, the schematic diagram for control section shows that all Input 1 to 10 is pulled-up. So they are
active-low. In PSC28A datasheet page 8, it says that "There are 22 digital output terminals on PSC28A which can be activated by buttons and joystick direction. All these digital outputs are
active low open collector output. User may connect it with output device like LED, buzzer, relay, motor or many more."
So I think you can connect PSC28A outputs to K8023 control section inputs with 220 ohm resistors in series.
