B&B Electronics BB-5144 RS-232 to RS-422/485 Serial Converter

The B&B Electronics BB-5144 is an industrial-grade serial interface converter designed to bridge RS-232 and RS-422/RS-485 serial communication standards. Built for reliable performance in demanding environments, this converter enables seamless connectivity between RS-232 devices and longer-distance RS-422/RS-485 networks commonly used in industrial automation, data acquisition, and process control applications.

Key Features:

• Converts RS-232 signals to RS-485 or RS-422 serial communication
• Supports extended cable distances made possible by RS-422/RS-485 differential signaling
• Industrial-grade construction for reliable operation in harsh environments
• Compact, standalone form factor for easy integration
• No external power required — powered via the RS-232 port (model dependent)
• Supports half-duplex (RS-485) and full-duplex (RS-422) communication modes

The BB-5144 is an ideal solution for extending legacy RS-232 equipment onto RS-485 multi-drop networks or RS-422 point-to-point links. B&B Electronics products are widely trusted in industrial settings for their durability and signal integrity.
