USB to Isolated 422/485 w/Plug Terminal Block and LEDs - B+B SmartWorx

Upgrade your USB-only PC with a rugged, isolated serial port that covers common industrial interfaces. The USB to Isolated 422/485 w/Plug Terminal Block and LEDs from B+B SmartWorx is a compact, plug-and-play converter that adds USB to RS-232 and USB to RS-422/RS-485 capabilities in a single device. With built-in galvanic isolation of up to 2 kV, this adapter protects your computer from ground loops and electrical noise while delivering reliable, asynchronous serial communication to remote devices, programming ports, sensors, and control equipment in the field. Designed for demanding environments, it ensures stable data transfer even when your equipment is located far from the host PC.

  • 2 kV galvanic isolation protects your USB host and connected devices from dangerous ground loops and voltage transients, enabling safe operation in industrial settings, data centers, and field installations.
  • Versatile interfaces: USB to RS-232, USB to RS-422, and USB to RS-485, providing a single, flexible solution for a wide range of serial requirements without swapping adapters.
  • Plug terminal block for quick, secure wiring in the field—durable screw-terminal connections simplify wiring to remote devices, sensors, and controllers while eliminating fiddly pin headers.
  • LED indicators offer immediate visual feedback for power and data activity, helping technicians diagnose connections and monitor throughput at a glance.
  • Compact, portable form factor designed to fit on a desk, inside enclosures, or mounted in a control cabinet, making it ideal for field deployments, programming ports, and machine automation projects.

Technical Details of USB to Isolated 422/485 w/Plug Terminal Block and LEDs

  • Isolation: 2 kV galvanic isolation between the USB host and the serial interfaces to minimize ground loop problems and protect equipment.
  • Interfaces supported: USB to RS-232, USB to RS-422, and USB to RS-485, enabling flexible connection options from a single device.
  • Wiring: Plug terminal block for straightforward field wiring—reliable screw terminals that stay secure in environments with vibration or movement.
  • Indicators: Built-in LEDs for power and data activity, providing quick at-a-glance status checks during installation and operation.
  • Power and form factor: USB-powered device with a compact footprint that fits easily on workbenches or inside small enclosures; no external power supply required for standard USB operation.

How to install USB to Isolated 422/485 w/Plug Terminal Block and LEDs

  • Step 1: Connect the USB end of the adapter to your computer’s USB port and allow any required drivers to install or complete the setup prompts.
  • Step 2: Attach your serial device to the plug terminal block using appropriate screw-terminal connections for RS-232, RS-422, or RS-485 as dictated by your target device.
  • Step 3: Power on your serial device if required and verify that the LED indicators on the adapter show power and activity as expected.
  • Step 4: Configure your software to use the new serial port. Identify the assigned COM port (or equivalent) and set the correct serial parameters (baud rate, data bits, parity, stop bits) for your application.
  • Step 5: Test the communication with a simple loopback or a known-good device to confirm reliable data transfer. If issues arise, check terminal block connections, cable wiring (RS-422 vs. RS-485 multi-drop configurations), and terminate lines if required by your setup.

Frequently asked questions

  • What interfaces does this adapter support? It provides USB to RS-232, USB to RS-422, and USB to RS-485 connections, with 2 kV isolation to protect equipment from ground loops.
  • Why is isolation important? Isolation helps prevent voltage transients and ground differences from affecting the host computer or other equipment, improving reliability in industrial and field environments.
  • Do I need an external power supply? No external power supply is typically required; the device is powered via the USB connection from your computer.
  • How do I wire the serial device? Use the plug terminal block to secure the appropriate RS-232, RS-422, or RS-485 wiring according to your device’s connector and protocol. Ensure correct polarity and termination as needed.
  • Is this compatible with multiple operating systems? The adapter is designed to work as a standard USB-to-serial bridge and should be compatible with common operating systems, but specific driver and software support may vary by system. Consult your device’s documentation for compatibility details.
