The B+B SmartWorx High Speed RS-232/422/485 Fiber Modem delivers durable, reliable serial-to-fiber conversion designed for industrial environments, remote monitoring, and mission-critical automation. This fiber optic modem enables seamless interoperability across legacy serial interfaces and modern networked systems by letting RS-232 devices communicate with RS-422 and RS-485 devices over fiber. The result is enhanced distance, improved immunity to electrical noise, and enhanced data integrity without sacrificing compatibility. Built to simplify integration, this device consolidates multiple standards into a single, compact converter, reducing the need for multiple adapters, isolators, or complex configurations. Whether you’re upgrading a factory floor line, connecting remote sensors, or linking distant control equipment, this modem makes it possible to preserve your existing investments while embracing fiber’s performance advantages.

  • Interoperability across serial standards: The modem is designed to bridge RS-232 to RS-422 and RS-485 networks, allowing mixed-standard connections without the hassle of separate converters. This means you can connect legacy equipment that speaks RS-232 directly to modern devices that rely on RS-422/485 signaling, all over a single fiber link. The flexibility of mixed standards reduces procurement complexity and accelerates project timelines, making it ideal for retrofits and new installations alike.
  • Automatic Send Data control for RS-485: When used with RS-485 networks, the modem incorporates Automatic Send Data (ASD) control, eliminating the need for driver software or manual handshaking. This feature streamlines deployment and minimizes configuration steps on devices that otherwise require vendor-specific drivers. ASD helps ensure reliable data transmission in half-duplex RS-485 systems, delivering smoother operation across longer cable runs.
  • Long-distance, noise-immune fiber connectivity: By converting serial data to fiber, the modem delivers superior resistance to electrical interference, ground loops, and EMI commonly found in industrial settings. Fiber optics enable extended reach well beyond copper capabilities, so you can place critical equipment farther from control rooms while preserving data integrity. The result is dependable performance in challenging environments, with reduced risk of data corruption due to electrical noise.
  • Plug-and-play installation with robust design: Designed for straightforward installation, the modem supports easy wiring of serial interfaces and fiber optic cables while maintaining a compact footprint suitable for panel mounting or rack integration. Its rugged construction is intended to withstand harsh environments, making it a trusted choice for manufacturing floors, oil & gas facilities, and remote automation sites. With simple configuration and clear signaling indicators, users can quickly verify link status and data flow at a glance.
  • Versatile applications and reliability: This fiber modem is well-suited for industrial automation, SCADA systems, remote telemetry, and sensor networks requiring secure, high-speed serial communication over fiber. By providing a single, reliable pathway for multiple serial standards to traverse a fiber link, it helps minimize latency, maximize uptime, and simplify system architecture. Its compatibility with common serial configurations and resilient performance make it a dependable cornerstone for dependable, long-range data exchange.

How to Install B+B SmartWorx High Speed RS-232/422/485 Fiber Modem

  • Power down all equipment before making connections to avoid electrical shock or damage. Ensure you have the correct power supply that matches the modem's voltage requirement.
  • Identify the serial interface on your legacy device (RS-232, RS-422, or RS-485) and connect it to the corresponding port on the modem using the appropriate, properly wired cable. Verify signal directions and DTE/DCE configuration to match the remote device.
  • Connect the fiber optic link to the modem using the correct fiber type (single-mode or multi-mode) and the appropriate connector. Ensure the fiber run is clean, free of excessive bending, and properly terminated to preserve signal integrity.
  • Power on the devices and monitor the status indicators on the modem. Look for link, activity, and fault indicators to confirm a healthy connection. If ASD is enabled for RS-485, verify that the data is transmitted and received as expected on the remote end.
  • Configure any required parameters (baud rate, parity, stop bits, and addressing as needed) to align with the local and remote devices. If the product supports auto-negotiation or ASD features, enable them according to the installation guidelines to simplify setup.
  • Test the link with representative data, verifying two-way communication between the RS-232/RS-422/RS-485 devices across the fiber. Conduct fault testing, including disconnects and line noise simulations, to ensure robust operation under real-world conditions.

Frequently asked questions

  • Q: What serial standards does this modem support?
  • A: It supports RS-232, RS-422, and RS-485, enabling flexible connections between devices that use different serial interfaces.
  • Q: Do I need drivers for RS-485 communication?
  • A: No separate driver software is required for RS-485 because the modem includes Automatic Send Data (ASD) control to manage signaling automatically.
  • Q: Why choose fiber over copper for serial communication?
  • A: Fiber provides superior immunity to electrical noise, longer transmission distances, better security, and reduced risk of ground loops, making it ideal for industrial environments and remote installations.
  • Q: Can I mix RS-232 with RS-422/485 on the same link?
  • A: Yes, the modem is designed to mix and match standards so RS-232 devices can connect to RS-422/485 devices over a single fiber link, simplifying system design.
  • Q: Is the modem suitable for harsh environments?
  • A: The design emphasizes reliability in industrial settings, with rugged construction intended to withstand challenging conditions typical of manufacturing floors and remote sites.

Awesome, portable room divider for larger rooms
Color: Black, Color: Black
I chose this room divider to use in my son's room that also serves as my home office! It is 72" x 72" in size, so it truly blocks out the other side of the room for optimal privacy. Once it's assembled, it's mildly sturdy - as long as you can bet both ends with the "feet" in line with the ground. I wish that the framework poles had more of an interlocking system so that the divider was easier to erect. I assembled this on carpet, so I had some issues getting the divider to stop moving. It takes a lot of work to set up, as it is massive, so definitely have someone help you. I would suggest adding weights of some sort to the feet of this divider to keep it from shifting. I ended up leaning mine against a bookcase shelf so it wouldn't lean. All and all, this is a great product if you are looking to make a room multipurpose.

As described
Color: Black
Light weight, easy to put together and you can disconnect the ends and just roll the whole thing nice and tight for quick out of the way storage. Pretty sturdy, doesn't fall over if you bump into it, you could use it outside but if there's a lot of light you can see through a tiny bit if you're really close but I only tested this indoors so not sure about patio types
