The Crane NRI G-13.mft coin acceptor gets a UART serial interface by Davide Gironi.
The NRI G-13.mft by Crane (https://www.cranepi.com/) is a versatile and high secure coin validator.
It can be programmed using the propretary WinEMP software and PC interface, or event it has some DIP Switch that can be used to program the device. Unluckily it does not come with a UART interface. But it features a “machine tester” I/O interface we can use to track the inserted coins.
The solution uses an ATmega8 microcontroller. The UART to USB adapter chip is the Silab CP2102, attached to a microUsb port.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
