ATEN Altusen SN3000 series Secure Device Servers are external IP-based network devices that securely connect legacy serial RS-232 devices to an Ethernet network to be accessed remotely from a computer located anywhere, allowing you to expand the number of serial ports for any host computer over a network.
The SN3000 series is especially suited for industrial process control applications, given the abundant use of the Supervisory Control and Data Acquisition (SCADA) systems across many industries for collecting data from PLCs, meters, and sensors via serial ports. The SN3000 series bidirectionally translates data between serial and Ethernet formats, and facilitates access to the data from all data collection instruments from local and remote sites through an Ethernet network.
The SN3000 series has a number of useful operation modes. It supports secure TCP server / client, secure Real COM, and console management modes for security-critical applications, such as telecom, access control, and remote site management.
