The ICUSB2322X 2 Port Professional Grade USB Serial Adapter converts a single USB port to two RS232 serial ports allowing you to connect to, monitor and control your serial devices. Rugged metal construction and sturdy wall-mount brackets provide a robust solution for both harsh industrial environments and simple desktop installations.

Powered by USB, the device does not require a power outlet for most standard applications. For installations requiring more power through the RS232 ports, the hub supports connection of an external power adapter (not included) to the integrated DC jack or terminal block. Once connected, the adapter retains assigned serial COM port values, allowing the same values to automatically be re-assigned to the ports provided by the adapter in the event it is disconnected, then re-connected to the host computer.

This innovative Serial adapter offers a professional grade solution for connecting legacy or industrial RS232 serial devices to more modern computers, or computers with unused USB ports – perfect for connecting serial modems, barcode scanners or any device with serial sync through USB, eliminating the expense of upgrading serial peripherals for USB compatibility.

Backed by a 2-year warranty and free lifetime technical support.

The Advantage

  • Multiple ports with COM port retention give you hassle-free control of several serial devices without having to remember where each one was last connected
  • Rugged all-metal enclosure for added durability in harsh environments
  • Easy plug and play installation with our USB Powered adapter - no power outlet required


Perfect for IT Administrators looking to add legacy functionality to newer notebooks, PCs and servers that lack an integrated RS232 port

Connect, monitor and control industrial/automotive sensors and equipment

Connect bar code scanners, receipt printers and other point of sale devices
