B&B Electronics BB5414 RS-232 to RS-485/RS-422 Serial Converter

The B&B Electronics BB5414 is an industrial-grade RS-232 to RS-485/RS-422 serial converter designed for reliable data communication in demanding environments. This compact interface converter bridges the gap between RS-232 serial ports and RS-485 or RS-422 multi-drop networks, making it an essential component for industrial automation, process control, and data acquisition systems.

Key Features:

• Converts RS-232 signals to RS-485 (2-wire) or RS-422 (4-wire) for extended network reach
• Supports multi-drop RS-485 networks for connecting multiple devices on a single bus
• Plug-and-play operation — no external power supply required; powered directly from the RS-232 port
• Rugged industrial design suitable for use in harsh environments
• Compact form factor for easy installation in tight spaces
• LED indicators for transmit and receive data activity monitoring
• DB9 connector interface for straightforward integration with standard serial ports

The BB5414 is manufactured by B&B Electronics Manufacturing Company (now Advantech B+B SmartWorx), a trusted leader in industrial connectivity solutions. This converter is ideal for integrators and engineers who need to extend RS-232 connections over longer distances or connect to RS-485/RS-422 device networks without replacing existing equipment.
