StarTech.com USB to RS232/RS485/RS422 8 Port Serial Hub Adapter - Industrial Metal USB 2.0 to DB9 Serial Converter - Din Rail Mountable

The StarTech.com USB to RS232/RS485/RS422 8 Port Serial Hub Adapter is engineered for professionals who need reliable, scalable serial connectivity in demanding environments. Built with an industrial metal enclosure and designed for DIN rail mounting, this eight-port hub seamlessly bridges USB-enabled computers with legacy serial devices. Whether you are configuring point-of-sale terminals, data loggers, CNC controllers, industrial controllers, or measurement instruments, this versatile hub delivers robust performance, flexible port configuration, and durable operation in factories, laboratories, and field deployments. It simplifies logistics by consolidating eight serial interfaces into a single convenient USB connection, letting you expand your serial footprint without sacrificing desk space or reliability.

Thanks to its universal DB9 connectors, multi-mode serial capabilities (RS-232, RS-485, RS-422), and rugged steel body, the hub is built to withstand the bumps and vibrations of industrial settings while remaining compact enough to fit into equipment racks and control panels. The USB 2.0 interface provides broad compatibility with modern laptops and desktops while ensuring stable data transfer and low latency for real-time control tasks. This is not just a USB adapter; it is a scalable serial hub that grows with your automation needs, enabling faster deployment, easier maintenance, and cleaner cabling.

  • 8-port multi-mode serial hub: Converts a single USB 2.0 connection into eight independently configurable RS-232/RS-485/RS-422 DB9 serial ports. This enables you to connect multiple legacy devices—from sensors and meters to CNC machines and POS terminals—without swapping cables or adapters. The ability to mix port configurations on a single hub makes it ideal for heterogeneous equipment environments where different serial standards must coexist.
  • Industrial metal enclosure & DIN rail mountability: The rugged, metal housing is designed for harsh industrial settings and offers reliable shielding against EMI. The included DIN rail mounting capability makes it easy to integrate the hub into control cabinets, electrical enclosures, or machinery housings, reducing footprint and simplifying system layouts. This design is purpose-built for long-term operation in manufacturing floors, labs, and field sites where tamper resistance and durability matter.
  • USB 2.0 interface with plug-and-play versatility: Connects to laptops, workstations, or embedded systems via USB 2.0 for broad compatibility and straightforward installation. The hub supports hot-plugging in many environments, allowing you to add or remove devices with minimal downtime. Whether you’re upgrading an old control system or expanding an existing one, you’ll appreciate the quick setup, reliable data transfer, and consistent port performance across a range of software ecosystems.
  • Comprehensive serial protocol support: The hub’s ports can be configured to operate with RS-232, RS-485, or RS-422 protocols, giving you the flexibility to interface with a wide array of devices. This multi-protocol capability is perfect for mixed-signal environments, where some devices require high-precision RS-422 or RS-485 differential signaling while others rely on the straightforward RS-232 interface. This versatility simplifies your inventory and reduces the need for multiple adapters in your racks.
  • Designed for reliability in automation and data collection: Ideal for automation systems, instrumentation, industrial PCs, and data acquisition setups. The robust construction minimizes vibration-induced failures, and the dedicated eight-port arrangement reduces contention and improves throughput when many serial devices operate concurrently. With strong build quality and a focus on operational continuity, this StarTech hub helps keep critical machines and processes online with fewer interruptions.

how to install StarTech.com USB to RS232/RS485/RS422 8 Port Serial Hub Adapter

  • 1. Locate a suitable mounting area within a control cabinet or on a stable desk space near your computer. If you plan to use the hub in a DIN rail setup, secure it to the rail as per your enclosure guidelines, ensuring adequate ventilation and cable routing to prevent stress on connectors.
  • 2. Connect the USB 2.0 cable from the hub to an available USB port on your laptop, desktop, or embedded controller. Ensure the USB cable is of adequate length to reach both the host and the hub without tension.
  • 3. Power on your host system (if required for power delivery through USB, which is common for USB hubs). In most standard configurations, the hub will draw power from the USB connection; no separate power supply is necessary unless you are running high-current serial devices or a very long cable run.
  • 4. Install or confirm drivers (if prompted) so the hub is recognized as a USB-to-serial device with eight serial ports. On Windows, macOS, and Linux ecosystems, modern USB-to-serial adapters are typically supported, with the driver mapping the eight DB9 ports to distinct COM ports or device paths in your system.
  • 5. Connect your RS-232, RS-485, or RS-422 devices to the appropriate DB9 ports. Configure each port in your software or terminal program to match the device’s serial settings (baud rate, data bits, parity, stop bits, and flow control). This hub is designed to simplify deployment by letting you assign devices to separate ports while maintaining centralized control from the host computer.

Frequently asked questions

  • Q: What operating systems are supported? A: The StarTech.com USB to 8-Port Serial Hub is designed to work with common operating systems that support USB-to-serial devices. It typically works with Windows, macOS, and Linux distributions via standard USB drivers. If you rely on specialized software, you may need to install additional drivers provided by the OS or device manufacturer to ensure seamless port reassignment and driver stability.
  • Q: Do I need an external power supply? A: In most cases, the hub is powered through the USB connection to the host. External power is not required for typical operation. If you connect high-current serial devices or run a dense configuration with many devices simultaneously, you may consider a powered USB hub or an arrangement that ensures adequate power delivery to the hub and connected devices.
  • Q: Can I mix RS-232, RS-485, and RS-422 on the same hub? A: Yes. Each of the eight ports can be configured individually for RS-232, RS-485, or RS-422 to support a mixed environment. This flexibility is particularly useful in laboratories or manufacturing floors where different instruments require different serial signaling standards.
  • Q: Is the hub suitable for DIN rail installation? A: Absolutely. The hub is designed with an industrial metal enclosure and DIN rail compatibility, making it a natural fit for electrical cabinets, control panels, and other industrial installations where space efficiency, durability, and organized cabling are priorities.
  • Q: How do I configure the serial port settings? A: After the hub is recognized by your system, use your terminal software or device management tools to configure each port’s parameters (such as baud rate, data bits, parity, stop bits, and flow control). Since the ports can operate in RS-232, RS-485, or RS-422 modes, ensure you set the correct protocol on each port according to the connected device’s requirements.
