Convert a single USB port into eight serial ports, and connect multiple hubs together for a scalable solution

This 8-port USB-to-serial adapter hub provides an easy and cost-efficient way to add RS232 serial capability to your industrial setting. It features a sturdy, rack-mountable chassis, and supports daisy chaining, so you can connect multiple hubs together to increase your serial device port count.

A scalable solution for changing needs

This rack-mountable USB serial hub (FTDI) lets you add eight serial ports (RS232), with full control from your desktop or laptop computer system using a single USB port. The daisy-chain function gives you a cost-effective and scalable way to increase your serial port count and expand as your needs grow, without investing in a more expensive serial hub.

Providing full control of your serial components from a single device, the USB serial hub is ideal for a multitude of applications including industrial automation, self-serve automated kiosks, and monitoring of cameras and security systems.

Built-in convenience

The hub features COM port retention, which retains the assigned serial COM port values. This ensures that the same values are automatically re-assigned to the port provided by the adapter, in the event it is disconnected and re-connected to the host computer.

The hub features a reliable FTDI USB-to-serial chipset, which provides easy installation into a broad range of operating systems.

Meets the demands of industrial environments

With its all-metal chassis, this rugged, rack-mountable hub fits into standard 19-inch server storage racks to provide an efficient industrial serial solution. It supports an extended operating temperature range of -40¡C to 85¡C (-40¡F to 185¡F), ensuring reliable performance even in the harshest environments. The USB-serial hub includes both an AC adapter and terminal block power, providing versatile power options.

The ICUSB23208FD is backed by a 2-year warranty and free lifetime technical support.
