Product information

Description

The StarTech.com Serial Hub USB to RS232/RS485/RS422 ICUSB234854I converts a single USB port into four independent serial ports, supporting RS232, RS422, 4-wire and 2-wire RS485 operating modes. Housed in an IP30-rated metal enclosure with flexible mounting options, the adapter is intended for connecting, monitoring and controlling serial devices such as sensors, barcode scanners and LED signage. The unit includes 15 kV ESD protection, screw-locking USB and host connections, and supports data rates up to 921 Kbps.

Advantages

This compact serial hub adds four COM ports to a laptop or desktop over USB 2.0, providing support for multiple serial protocols in a single device. Its rugged metal housing and IP30 rating make it suitable for industrial or mission-critical environments, while 15 kV ESD protection and screw-locking connectors reduce the risk of downtime and accidental disconnection. High-speed UARTs enable fast data transfers up to 921 Kbps, and the product includes both a DIN-rail mounting kit and a wall-mount bracket for flexible installation.

Suitable for

  • Connecting industrial sensors and controllers
  • Integrating barcode scanners and point-of-sale equipment
  • Managing LED signage and display controllers
  • Serial device monitoring and data acquisition in harsh environments
  • Retrofit or expand legacy serial equipment via USB

How to use

Connect the included screw-locking USB-B cable from the Serial Hub to an available USB port on your computer. Mount the hub using the built-in wall bracket or the included DIN-rail kit as needed for your environment. Attach your serial devices to the appropriate serial ports, selecting the required operating mode (RS232, RS422, RS485 4-wire or RS485 2-wire) and configure the host system serial settings (baud rate, parity, stop bits) to match the connected devices. Install any required drivers for your operating system before use.

Usage recommendations

For reliable operation in industrial environments, install the hub in a protected location or enclosure if exposed to dust or liquids beyond IP30 protection, and ensure proper grounding. Use the screw-locking connectors to prevent accidental disconnection and enable ESD precautions when connecting or servicing serial cabling.
