The hardware support can enable both a “strong signal driving” mode as well as a “weak signal driving” mode. In the weak mode, a biasing, or attenuating, or voltage-dividing resistor can be temporarily inserted between a transmitter, or voltage source, and the transmission line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Collision detection in EIA-485 bus systems","description":"A communication module is disclosed for Intelligent Electronic Devices (IEDs) which can implement the EIA-485 standard, including an intelligent hardware support that can allow a known software-based ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9678919","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
