We have an old can machine which uses a NRI G13.6000 (flat cable ribbon serial) as a coin acceptor. Now I need to trick the machines relays board to think that a payment has been made.
The NRI has several output channels, but the one I need (channel 8) sends out a pulse to the board. I need to emulate that Pulse with the push of a button.
This is the description of the output channel of the NRI:
NPN 100ms 10mA active low w/ 47K pull-up to +5V
Is there anyone who knows how to pull this off?
