B&B Electronics 422LP25N RS232 to RS422 Converter

The B&B Electronics 422LP25N is a two-channel, port-powered RS-232 to RS-422 converter that enables reliable, long-distance serial communication by translating unbalanced RS-232 signals into balanced RS-422 signals. The device uses DB-25 connectors on both the RS-232 and RS-422 sides, allowing straightforward integration with PCs and RS-422 peripherals without requiring an external power supply. Designed for industrial and laboratory deployments, it supports RS-422 operation over distances up to about 4,000 feet (approximately 1.2 km) under suitable cable and load conditions. With two independent channels, it can handle parallel RS-232 data streams, making it suitable for multi-point or dual-device configurations in a single enclosure.
