• Secured operating modes
• Redundant power input
• Supports Modbus gateway

For secure serial data transfer
The Secure Device Server SN3401P is an external IP-based network device that securely connects older RS-232/422/485 serial devices to an Ethernet network and provides remote access from any computer.

The SN3401P is particularly suitable for industrial process control applications as Supervisory Control and Data Acquisition (SCADA) systems are widely used in many industries for acquisition of data from PLCs, meters, and sensors via serial interfaces. The SN3401P translates data bidirectionally between serial and Ethernet formats, allowing access to the data of all data collection devices from local and remote locations over an Ethernet network.

The SN3401P has a number of useful operating modes. It supports secure TCP server/client, secure serial tunneling server/client, secure real-COM and console management modes for safety-critical applications, such as telecommunications, access control and remote site management. In addition, the IEEE 802.3af compatible models can be powered from a PoE PSE device without an additional power supply.
