B&B Electronics BB2617 RS-232 to RS-485/RS-422 Serial Converter

The B&B Electronics BB2617 is an industrial-grade RS-232 to RS-485/RS-422 serial interface converter designed for reliable data communication in demanding environments. This compact converter bridges the gap between RS-232 serial ports and RS-485 or RS-422 multi-drop networks, allowing legacy RS-232 equipment to communicate over longer distances and in electrically noisy industrial settings.

Key Features:

• Converts RS-232 signals to RS-485 (2-wire) or RS-422 (4-wire) communication standards
• Supports data rates up to 115.2 kbps
• Automatic transmit/receive direction control (no handshaking required)
• Extended communication distances up to 4,000 feet (1,200 meters) on RS-485/RS-422
• Industrial-grade design suitable for harsh environments
• DB9 connectors for easy integration with standard serial ports
• Wide operating temperature range for industrial applications
• Plug-and-play installation — no software or drivers required
• LED indicator for power/activity status

The BB2617 is ideal for connecting PLCs, sensors, meters, and other RS-232 devices to RS-485 or RS-422 networks commonly used in industrial automation, building control systems, and data acquisition applications. Its transparent operation makes it compatible with virtually any RS-232 device without the need for configuration or special software.
