Opengear's secure device servers, comprising the SD4002 two-port unit and SD4008 eight-port unit, offer a high level of security together with an ability to control any device with an RS232/422/485 serial port or ethernet interface.

Utilities, refineries, factories, processing plants and health clinics use an array of devices in their control systems to digitally automate tasks and monitor critical information such as pressure, temperatures, speed, vital health statistics etc. Today's control systems are sophisticated and are habitually connected to the broadband network infrastructure. However, most device servers are only capable of coupling 10 to 20-year-old legacy serial devices (meters, SCADA appliances, PLCs and sensors) onto an IP network. They can't connect to modern network devices and don't provide strong security.

With secure tunnelled HTTP, RDP and VNC support and a rich set of serial port communications features, the SD4002 and SD4008 are suitable for central and off-site management and control.
