Industrial 4 Channel RS232 RS485 RS422 Fiber Media Converter Dual Ring Redundant

Industrial 4 Channel RS232 RS485 RS422 Fiber Media Converter Dual Ring Redundant

Model: LNK-GYS200 series

 Product Description & Overview

The Industrial 1~4Ch RS232/RS422/RS485 Double-ring Fiber Media Converter represents an

advanced networking solution for industrial serial communication systems requiring high reliability

and flexible topology configurations. This robust media converter supports 1 to 4 channels of RS232,

RS422, and RS485 serial interfaces over fiber optic infrastructure, enabling versatile network

architectures including point-to-point connections, chain networks, star configurations, and redundant

ring topologies with self-healing capabilities. The dual-ring protection mechanism ensures continuous

operation by automatically detecting fiber breaks and rerouting data through alternative paths within

30 milliseconds, maintaining uninterrupted communication in mission-critical industrial applications.

Engineered specifically for demanding industrial environments, this converter effectively resolves the

traditional limitations of serial interface communication by extending transmission distances while

maintaining high-speed data rates up to 115.2kbps per channel. The implementation of fiber optic

technology completely eliminates electromagnetic interference, ground loop problems, and lightning-

induced damage that commonly plague copper-based serial networks. The device's advanced optical

isolation provides complete electrical separation between connected equipment, significantly enhancing

data communication reliability, security, and confidentiality across all transmission channels.

This sophisticated media converter finds ideal application in various industrial sectors including factory

automation, process control systems, and critical infrastructure monitoring where network reliability is

paramount. The flexible topology support allows for seamless integration into existing networks while

providing scalability for future expansion. With its robust construction and intelligent self-healing capabilities,

this solution offers industrial operators a reliable and secure communication platform that dramatically

improves network resilience while reducing maintenance costs associated with traditional serial

communication systems in electrically challenging environments, making it particularly suitable for

transportation management systems, energy distribution networks, and industrial IoT applications

requiring guaranteed data delivery.
