Digital One Line Link (DOLLx8) is a technology architecture that consists of data communication protocol, synchronous serial data bus and a communication system for embedded systems and electronics. DOLLx8 use ASCII characters in its data protocol, differential signaling in the bus system, where the communication consists of an active long-distance technology based on system logic where handling of the communication is done automatically by the microcontroller and its internal embedded Real-time operating system (RTOS) and software.
