Remote Access Appliance Autosensing Communication Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional remote access appliances require separate interfaces for Ethernet and serial connections, necessitating multiple ports and manual configuration, which is inefficient and inflexible.
Innovation Solution
The implementation of an autosensing subsystem within a remote access appliance that automatically detects and configures communication protocols, allowing a single RJ-45 port to handle both Ethernet and serial connections by identifying the connected device and its pinout configuration, thereby eliminating the need for multiple ports and manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate interfaces are used for Ethernet and serial connections, then communication reliability is improved, but device complexity and number of ports increase
Solution Approach 1:
The patent implements a universal communication port that can function as either an Ethernet interface or a serial interface based on automatic detection. The single RJ-45 port is designed to accommodate both connection types through pinout detection and protocol identification, eliminating the need for separate dedicated ports while maintaining communication reliability for both interface types
2Measurement precision
If manual configuration is required for interface selection, then communication precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-configuration through automatic protocol detection and identification. When a device connects to the communication port, the system automatically detects the pinout configuration, identifies whether it is an Ethernet or serial protocol, and configures the appropriate interface without requiring manual user input, thereby maintaining precision while dramatically improving ease of operation
3Adaptability or versatility
If a single port handles both Ethernet and serial protocols, then adaptability is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system performs preliminary detection of the connected device's pinout configuration and protocol type immediately upon connection establishment. By proactively identifying whether the connected device uses Ethernet or serial protocol and detecting the specific pinout arrangement before full communication begins, the system simplifies subsequent protocol handling and reduces the overall detection complexity
Data Source
AI summary
A remote access appliance (“appliance”) is disclosed which includes an autosensing subsystem that automatically senses when an Ethernet device or a serial device has been connected to it. The appliance then automatically configures one or more internal components to operate with the sensed/connected Ethernet device or serial device. When a serial device connection is detected, the appliance is further able to automatically detect which one of two different, predetermined pinout configurations is being used by the serial device, and to automatically configure one or more internal components to accommodate the detected pinout configuration.
