About this product

Convert a USB port into 16 RS232 serial ports in an industrial rack-mountable chassis - and daisy chain multiple hubs for a scalable solution

Here's an easy and cost-efficient way to add RS232 serial capability to your industrial setting. This 16-port USB-to-serial adapter hub 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 lets you add 16 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 higher cost 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.

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.
