Executive to RS232/TTL/USB interface

(active product - on demand)

This is an universal module that can be used as a bridge between TTL (3V3), USB or RS232 device or computer/PC/Raspberry Pi, etc.) and an Executive (Protocol A) enabled vending machine.

It offers a very simple serial protocol that can be easily implemented in any programming language, without the need of learning Executive protocol and managing some low level restrictions that are needed to connect to the vending machine.

Also, we are offering a Python 3 demo application that can be used at a wrapper or as a sample to speed up your development.

The manual is available for download here and the Python 3 demo application (requires PySerial 3.0.1) is available for download here.
