RS-232/422/485 Secure Device Servers

1- and 2-port RS-232/422/485 secure device servers  

ATEN secure serial device servers are external IP-based network devices that securely connect legacy RS-232/422/485 serial devices to an Ethernet network to be accessed remotely from a computer located anywhere, allowing users to expand the number of serial ports for any host computer over a network.

ATEN secure serial device servers are 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. ATEN secure serial device servers bi-directionally 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.

ATEN secure serial device servers has a number of useful operation 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 telecom, access control, and remote site management.

ATEN secure serial device servers can be used as standard Modbus gateway to convert between Modbus TCP and Modbus RTU / ASCII protocols. It can integrate Modbus serial slave devices seamlessly into an existing Modbus TCP network and thereby make them accessible to serial master devices.

An easy-to-use, secure, and reliable solution makes it easier to connect a wide range of serial devices to an IP-based Ethernet LAN in an instant. The ATEN ATEN secure serial device servers secure device server provides simple, fast serial-to-Ethernet connectivity, allowing users to remotely access serial RS-232/422/485 devices from a PC located anywhere. With various reliable features, ATEN secure serial device servers are ideal for commercial and industrial process control applications.
