A Greener Serial-to-Ethernet Solution

The SED2 is a small but powerful ARM-based serial-to-Ethernet SoC with RAM and Flash embedded. With the ARM7 inside, the SED2 series becomes the lowest power consumption device server in the world. The SED2 series saves at least 50% on power consumption compared to existing solutions on the market, helping engineers meet the tough environmental compliance challenges found in today’s industrial environments.

3-step Web-based Configuration

The SED2’s 3-step web-based configuration tool is straightforward and user-friendly. The SED2’s web console guides users through 3 simple configuration steps that are necessary to activate the serial-to-Ethernet application. With this speedy 3-step web-based configuration, a user only needs to spend an average of 30 seconds to complete the settings and enable the application, saving a great amount of time and effort.

COM Port Grouping

The SED2’s COM Grouping function allows you to create a COM Group and redirect data from it to several physical COM ports on device servers. With COM Grouping, you will be able to control multiple physical serial ports simultaneously by operating only one COM port.

The SED2 series can conveniently connect up to 2 serial devices to an Ethernet, allowing you to network your existing serial devices with only basic configuration. With SED2 series, you can both centralize the management of your serial devices, and distribute management hosts over the network. SED2 series can be used to connect different devices for remote management, each serial port operates independently to provide maximum versatility, each port can be operate in Driver, TCP Server, and TCP Client mode independently.
