Alloy SCR460ST-3 Serial to Fibre Media Converter

The Alloy SCR460ST-3 is a versatile dual-purpose serial-to-fibre media converter designed for robust industrial and commercial communication applications. It provides a RS-232/RS-422/RS-485 triple-mode DB-9 serial interface and an ST-terminated singlemode fibre port capable of transmitting data up to 20 kilometres.

Ideal for extending serial data and control signals over long distances, the SCR460ST-3 supports automatic baud rate detection (up to 460.8Kbaud) and direction control, enabling seamless plug-and-play operation in varied serial protocols. Its compact, rugged all-metal enclosure provides high immunity to electromagnetic and electrostatic interference (EMI/EMS), ensuring reliability in challenging environments.

The converter may be used as a standalone device powered by the included external plugpack or installed as a hot-swappable module within Alloy's DCR12 Series 12-slot rackmount chassis for convenient system integration and maintenance.

Key benefits include:

• Triple mode RS-232/422/485 serial interface with auto-detection


• ST singlemode fibre connection supporting distances up to 20 km


• Auto baud rate and direction control for flexible serial communication


• Robust metal casing with high EMI/EMS immunity


• Comprehensive LED indicators for real-time status monitoring


• Dual installation modes: standalone or compatible rackmount module
