US 2026/0095346 A1 · A SERIAL ASYNCHRONOUS COMMUNICATIONS NETWORK, A NETWORK INTERFACE MODULE AND METHODS FOR TRANSMITTING AND RECEIVING MESSAGES OVER THE NETWORK

Abstract

A serial asynchronous communications network to allow a number of electronic devices, controllers and/or monitors to be communicably connected to one another. Embodiments of the invention provide for an easily expandable network to be realized and allow for an efficient method for transmitting and receiving messages over the network. Embodiments of the invention may be deployed in a network having a communications bus which may be realised as a single wire, track or cable. Other embodiments are suitable for a communications bus realised as a pair of wires operating in differential mode. The pair of wires may have a twisted pair configuration according to some embodiments. Embodiments of the invention also include provision for bus arbitration, thus avoiding collisions on the bus when a plurality of actors attempt to communicate over the bus simultaneously.

Dependent claims

A method for transmitting a digital message from at least one electronic device to at least one further electronic device over a serial asynchronous communications network comprising a communications bus to which the electronic device and the further electronic devices may be communicably connected, the message comprising at least a message payload comprising m data bits, the method comprising:

encoding at least a first n contiguous data bits of them data bits of the message payload, said n contiguous data bits representing one from 2n different n-bit code values depending on a combination of binary states of said n contiguous data bits;
and
driving a signal having a waveform onto the communications bus according to said encoding of then contiguous data bits, the waveform thus comprising at least a first pulse having a pulse width selected from one from 2n different pre-determined pulse widths depending on the value of then-bit code represented by said n contiguous data bits.
