A Novel Single-wire Communication Method using Analog Wave for A Universal Connector

Abstract

Various devices such as computer and peripheral device contribute to our lives. Because there is a wide variety of device, the types of device connector standard are increasing. A converter for converting the electrical signal of the pin in a connector is required for communication with different connector standard. However, there is a problem that the number of converters for interconnection continues to increase when the connector standard continues to increase. This paper proposes a communication method for the universal connector that can automatically communicate between different connector standard without the converter. The universal connector negotiates at the beginning of the connection using the electrical signal of the pin in the connector. The negotiation using the electrical signal of the pin requires a single-wire communication. Machine with single-wire communication requires to understand connection partner's performance because available machines with the universal connector do not strictly limit the partner. In this paper, we propose a novel single-wire communication method that each machine understands performance of connection partner for the universal connector. The performance of the proposed method was evaluated by simulation.
