Description
Meet the B&B Electronics 9 PIN 232 FO MODEM W/HANDSHAKE, a high-performance serial to fiber optic converter engineered for robust industrial networking. This compact module enables seamless communication between RS-232 devices and RS-422/485 networks by translating serial signals into fiber-optic transmission, delivering long-distance reach, superior noise rejection, and galvanic isolation. Ideal for factory floors, remote monitoring, and control systems, this device replaces multiple adapters and isolators with a single, reliable solution that simplifies installation while preserving data integrity and timing. Whether upgrading legacy equipment or expanding an existing network, this 9-pin to fiber modem is designed to maximize uptime and minimize infrastructure costs.
- Flexible protocol compatibility: Connect RS-232 devices on the local side to RS-422/485 devices on the remote side through a fiber optic link. This enables mixed-standard deployments and streamlines integration by replacing separate converters and isolators with one versatile module.
- Automatic Send Data (ASD) control for RS-485: The onboard ASD feature manages bus control automatically, eliminating the need for specialized driver software and reducing configuration time. This is particularly beneficial in multi-drop RS-485 networks where bus contention can impact performance.
- Fiber optic advantages for reliability: Transmission over fiber provides immunity to EMI/RFI, eliminates ground loops, and delivers galvanic isolation. These characteristics are essential in environments with electrical noise, varying ground potentials, or safety requirements.
- Plug-and-play deployment: Designed for straightforward installation with standard serial cabling and fiber links. Its compact form factor fits easily into enclosures and on equipment racks, enabling quick integration into existing systems without extensive rewiring.
- Durable, industrial-ready design: Built to withstand challenging environments, the modem features rugged connectors and a form factor suitable for deployment in manufacturing, remote sites, and process control installations.

How to Install B&B 9 PIN 232 FO MODEM W/HANDSHAKE
Install the B&B 9 PIN 232 FO MODEM W/HANDSHAKE by following these general guidelines to ensure reliable operation and optimal performance. Always refer to the equipment manuals and safety guidelines for your specific environment.
- Prepare the system: Ensure power availability and verify that you have the appropriate fiber optic transceiver and fiber cabling rated for your network distance and bandwidth requirements. Confirm the RS-232 device and the RS-422/485 devices are powered and ready for integration.
- Connect the RS-232 side: Attach the RS-232 device to the 9-pin D-sub (DB9) port according to the host’s DTE/DCE orientation. Use standard straight-through or crossover serial cables as required by the device and the modem’s configuration.
- Link the fiber side: Connect the fiber optic transmitter and receiver to the corresponding fiber ports, then run the fiber cable to the remote device or network node. Ensure proper polarity and secure connectors to prevent signal loss.
- Power and grounding: Apply the appropriate power supply as specified by the manufacturer. Verify grounding requirements and ensure the installation adheres to safety and electrical codes relevant to your facility.
- Configure the device: If ASD or handshake settings are adjustable, set them to factory defaults or adjust according to your network plan. In most cases, factory defaults provide a reliable starting point. Test with a known-good host to confirm data integrity and network throughput.
- Test and verify: Power up the system and verify link indicators, LED statuses, and basic data transmission between the local RS-232 device and the remote RS-422/485 device. Perform a loopback or end-to-end test to confirm reliability across the fiber link.
