Aten Serial interface extension
Product details
The Secure Device Server SN3402 is an external IP-based network device that securely connects older serial RS-232/422/485 devices to an Ethernet network and enables remote access from any computer.
The SN3402 is particularly suitable for industrial process control applications, as Supervisory Control and Data Acquisition (SCADA) systems are widely used in many industries for collecting data from PLCs, measuring instruments, and sensors via serial interfaces. The SN3402 translates data bidirectionally between serial and Ethernet formats, allowing access to data from all data acquisition devices from local and remote locations over an Ethernet network.
The SN3402 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.
The SN3402 can be used as a standard Modbus gateway to convert between Modbus-TCP and Modbus-RTU/ASCII protocols. It can seamlessly integrate serial Modbus slave devices into an existing Modbus-TCP network, making them accessible to serial master devices.
