Product information

Description

The EXSYS EX-1321-4K is a wired network adapter that provides Gigabit Ethernet connectivity (up to 1000 Mbit/s) via a USB host interface. It is designed for easy installation without opening the host system and can be used with notebooks, desktop computers or mounted in a 19-inch rack. A DIN-rail kit is included for rack installation. The adapter supports operation alongside an existing network card and includes 4 kV optical isolation on the network port for enhanced signal protection.

Advantages

The adapter delivers up to 1000 Mbit/s Ethernet performance over a USB 3.0/3.1 (Gen1) or USB 2.0 port, enabling high-speed wired network access. Installation does not require opening the computer, and the device can operate concurrently with an existing network card. Built-in 4 kV optical isolation helps protect the network interface. A DIN-rail kit is supplied for convenient 19-inch rack mounting.

Suitable for

  • Adding Gigabit Ethernet to laptops and desktops via USB
  • Industrial or rack-mounted setups requiring DIN-rail installation in a 19-inch rack
  • Environments where galvanic isolation or increased port protection is needed

Key specifications

  • Interface: USB 3.0/3.1 (Gen1) and USB 2.0 host
  • Network speed: 10/100/1000 Mbit/s (Gigabit Ethernet)
  • Isolation: 4 kV optical isolation on network port
  • Form factor: external USB-to-Ethernet adapter with DIN-rail kit for 19-inch rack
  • Color: grey

How to use

Connect the EX-1321-4K to a host device using a USB 3.0/3.1 (Gen1) or USB 2.0 port, then attach an Ethernet cable to the RJ45 network port. If rack installation is required, mount the adapter using the supplied DIN-rail kit in a 19-inch rack. The adapter can be used alongside an existing internal network card; driver installation may be required depending on the host operating system.

Usage recommendations

For best performance, use a USB 3.0/3.1 (Gen1) port and Cat5e or better Ethernet cabling to achieve Gigabit speeds. Ensure proper grounding and follow site-specific safety procedures when installing the adapter in industrial or rack environments.
