Prepares Serial Devices for the Network

The Industrial Serial Device Server allows almost any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over Ethernet, the serial device server transmits full-duplex and bi-directional data seamlessly between the four serial ports and the Ethernet network, through two 10/100 Ethernet ports or two 100/1000 SFP Fiber slots.

Provides Advanced Embedded Security

The serial device server embeds OpenVPN and IPsec VPN, tunneling data securely through the internet while preventing unauthorized control of your serial devices by malicious actors. Rapid Spanning Tree Protocol (RSTP) supports a backup Ethernet link if the primary one fails.

Easy to Use

Configure the unit over Ethernet by Telnet, Web browser, serial console, or our Windows® Utility. Packed in a rugged metal housing for wall or DIN-Rail mount with redundant 12-48 VDC power input and one relay output, the serial device server is ideal for almost any industrial and manufacturing automation process. Virtual COM software creates a virtual environment for applications accessed via TCP.

Ideal for Automation Fields and Harsh Environments

In industrial and manufacturing automation fields, the device server is used as a field device to connect to Ethernet through TCP/IP protocol directly. The server works in conjunction with PLCs, HMIs, barcode scanners, data terminals, and more. Its design protects it from very harsh EMC and environmental conditions, perfect for advanced applications.

Rugged and Flexible

The serial device server features embedded high EMC protection, wide-range temperature operation, programming, and installation flexibility in one device. PoE versions can be powered through Power-over-Ethernet (PoE 802.3af) without additional cabling and power supply. SDK versions allow you to use powerful hardware and develop your own applications.
