Overview

The LNK-IRS93 Series is an industrial-grade serial-to-fiber converter supporting RS232,

RS485, and RS422 protocols. It extends serial communication up to 2 km on multimode

fiber or 80 km on single-mode fiber, ensuring reliable, interference-free data transmission in

harsh industrial environments. Ideal for process control, stage lighting (DMX512), and traffic

systems, it provides plug-and-play operation with hot-swappable support and built-in

surge/ESD protection.

Features

Versatile Serial Support: RS232, RS485, RS422, fully transparent

Long-Distance Fiber Transmission: Up to 80 km on SMF, 2–5 km on MMF

High-Speed & Adaptive: Up to 2 Mbps, auto baud-rate, no configuration needed

Stage Lighting Ready: Supports high-speed DMX512 communication

Rugged Design: DIN-Rail & wall-mount, -40°C to +75°C operation

Reliable Protection: 15kV ESD, 1500W/sec surge protection

Diagnostics: LED indicators for easy monitoring
