Make Serial Devices Ready to the Network
The Industrial Serial Device Server SE5916 is an advance gateway for Ethernet (TCP/IP) and serial signal communications; allowing any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over Ethernet (both copper and fiber), offers full-duplex and bi-directional data seamlessly between the four available serial ports and the Ethernet network.

Advanced embedded security
SE5916 embeds IPsec VPN Encryption, that allows you to tunnel your data securely through the internet and prevent unauthorized control of your Serial Devices by malicious people.

Easy to Use
Flexible configuration options enable this unit to be setup over Ethernet by Telnet, Web Browser, Serial Console, LCM display or our Windows Utility. Packed in a rugged metal housing for 19’’ Racks, it is ideal for almost any industrial and manufacturing automation process. ATOP Virtual COM software provides a virtual environment for applications when accessing the device through TCP.

Specifically Designed for Automation Fields
In industrial and manufacturing automation fields, SE5916 is used as a field device to connect the Ethernet through TCP/IP protocol directly. It is also specially designed for conjunction with PLCs, HMIs, Barcode Scanners, Data Terminals, and much more..

Rugged and flexible for advanced developments
SE5916 embeds high EMC protection, programming and installation flexibility in one device. Our SDK versions allow you to make use of the powerful  hardware and develop your own applications on top of ATOP's reliable SDK.
