B&B HEAVY INDUSTRIAL 232/422/485 TO MM FIBER ST CNVTR

Extend your serial communications to the edge of your facility and beyond with the B&B Heavy Industrial 232/422/485 to MM Fiber Serial Converter. This rugged pair of devices lets two asynchronous serial endpoints talk over a multi-mode fiber link, delivering reliable half- or full-duplex communication at data rates suitable for industrial control, telemetry, and remote monitoring. By converting copper serial signals to fiber, these converters dramatically improve immunity to EMI/RFI, reduce ground loop issues, and enable distances up to 9 miles without sacrificing performance. If your operation relies on robust, low-noise serial links across factory floors, remote sites, or outdoor installations, this converter set is engineered to deliver consistent, long-distance connectivity with minimal maintenance.

• Long-range, fiber-based serial links: Achieve communication over two fibers at distances up to 9 miles (approximately 14 kilometers) between two converter units. This enables remote embedding of RS-232/RS-422/RS-485 devices without copper polluting noise-prone environments.
• Flexible protocol support: Seamlessly handle RS-232, RS-422, and RS-485 interfaces on the copper side, giving you the versatility to connect a wide range of equipment with different signaling standards. The pair can operate in half- or full-duplex modes depending on your network needs.
• Optimal performance for industrial environments: Fiber optics deliver strong resistance to EMI and RFI, motor noise, welding arcs, and other electrical interference common in manufacturing and processing facilities, helping maintain data integrity and reduce downtime.
• High data-rate capability for critical applications: When using RS-422/RS-485, you can transfer data at up to 460 kbps; for RS-232, data rates reach up to 115.2 kbps. This balance supports a broad array of devices, from legacy equipment to modern sensors, without bottlenecks.
• Durable, industrial-grade design: Built for harsh environments and continuous operation, these converters are designed to withstand the demands of heavy industry, making field installation straightforward and dependable for control rooms, production floors, and remote nodes.

how to install [product]

• Identify the two serial devices that will communicate and determine whether you will use RS-232, RS-422, or RS-485 on the copper side, as well as whether you need half- or full-duplex operation.
• Connect each device’s serial interface to the corresponding copper port on the converter unit, ensuring proper pinout alignment and connector compatibility for your equipment.
• Insert the two multi-mode fiber optic cables between the paired converters, aligning the transmit and receive fibers according to the device’s labeling to establish a bidirectional link.
• Mount the converters in a suitable enclosure or rack, securing them for vibration resistance and protection from environmental hazards common to industrial settings.
• Power the units and configure the duplex mode and any required link settings. Confirm link status with the indicator LEDs, and test the network by sending representative data between the connected devices to verify successful communication over the fiber link.
