Aten Altusen™ Secure Device Servers from the SN3000 series are external IP-based network devices that securely connect older serial RS-232 devices to an Ethernet network, allowing remote access from a computer at any location.

The SN3000 series is particularly suitable for industrial process control applications, as Supervisory Control and Data Acquisition (SCADA) systems are widely used in many industries to collect data from PLCs, measuring devices, and sensors via serial interfaces. The SN3000 series translates data bidirectionally between serial and Ethernet formats, enabling access to data from all data acquisition devices from both local and remote locations over an Ethernet network.

The SN3000 series features a range of useful operating modes. It supports secure TCP server/client, secure serial tunneling server/client, secure Real-COM, and console management modes for security-critical applications such as telecommunications, access control, and remote site management. Additionally, the IEEE 802.3af-compliant models can be powered by a PoE-PSE device without the need for an additional power supply.
