Preserve serial infrastructure where replacement is costly or disruptive. The Black Box IC1474A-F converts RS-232 to RS-422 in a bidirectional DB9-to-DB9 design, helping legacy controllers, peripherals, and control systems communicate over longer runs with stronger signal characteristics than standard RS-232 links. With support for speeds up to 115.2 kbps and distances up to 4,000 feet, this converter is built for environments where serial communication must remain stable across extended cable paths. It is also TAA compliant, making it suitable for procurement environments with sourcing requirements that go beyond basic functionality. The value is in precision. Instead of overbuilding the network or replacing equipment that still performs, this converter adapts the interface at the edge. That keeps projects focused, reduces downtime during retrofits, and protects the investment already made in installed serial hardware.
