12v input bypass....
Posted on 2011-09-13
im in a bit of a pickle...
i have 2 12v inputs going into a digital I/O that sends a signal to the computer via usb. the device is an advantec usb 4761.
the inputs to the computer work perfectly which which allow our access control system to allow people on and off of our site.
the issue im having is with the actual button on the screen. Since we moved away from using a volt free system the button no longer work and I need to make the application think its its receiving the necessary input from the usb I/O device.
I will post the code up in a moment when i am able to get back onto the machine.
any suggestions would be extremely gratefully recevied.
