Product information

Description

The StarTech.com 4 Port Serial Hub USB to RS232/RS485/RS422 Adapter is an industrial USB 2.0 to DB9 serial converter hub designed for professional automation and control applications. Featuring an IP30-rated steel housing, DIN rail mountability, and 15kV ESD protection, it ensures reliable data transmission in demanding environments by connecting RS232, RS485, and RS422 devices to a USB 2.0 host interface.

Advantages

This industrial metal USB to serial adapter hub adds four configurable serial ports and a USB 2.0 port to your system, incorporating level 4 surge protection and locking connectors to prevent accidental disconnections. Each port can be independently configured to support multiple communication protocols for legacy and modern hardware. The rugged construction and flexible power options ensure stable operation even in environments prone to voltage spikes and electrical noise.

Suitable for

  • Connecting barcode scanners, printers, sensors, and LED signage to a computer
  • Industrial automation and control applications requiring robust serial communication
  • Harsh environments where equipment demands IP30-rated protection and metal enclosures
  • Setups requiring DIN rail or wall mounting in professional control rooms

When it may not be suitable

This serial hub is not designed for standard consumer environments where industrial-grade durability, metal housings, and specialized mounting options are unnecessary. It may also not be suitable for applications that require high-speed USB data transfer rates beyond what USB 2.0 and serial baud rates can provide.

Key specifications

  • Host interface: USB 2.0 Type-B
  • Hub interfaces: Serial (RS232, RS422, RS485)
  • Ports quantity: 4 serial ports
  • Housing material: Steel with IP30 rating
  • Protection: 15kV ESD protection
  • Power output: 12 V, 1 A

How to use

Connect the adapter to your computer using the included USB cable, ensuring the screw-locking connections are securely fastened. Install any required drivers for your operating system, such as Windows, macOS, or compatible server systems. Configure each serial port according to your connected device protocol requirements, attach your serial devices to the DB9 ports, and apply power using the included adapter or USB input.

What to consider before purchase

  • Verify that your operating system is compatible with the adapter drivers
  • Confirm the required serial protocol of your peripheral devices
  • Check available physical space for DIN rail or wall mounting

Usage recommendations: Secure all screw-locking connections to prevent accidental disconnection during operation and ensure proper ventilation around the metal housing in enclosed industrial spaces.
