Secure RS-232 Cross-Domain Isolators

The Secure RS-232 Isolators receive an RS-232 command from any connected device and send it unidirectionally forward to its destination device, ensuring no return signal from the destination to the originating device.

The FF11N-4, FT11N-4, and FXJ11N-4 are especially suited to protect against data leakage in any scenario where command and monitoring information are sent between two otherwise separated networks. SCADA, System synchronization, control commands, and information sharing can all be done securely via the Secure RS-232 Isolator family. The CP11N-4 is designed explicitly for user-prompted copy-and-paste commands between two Windows computers that transfer the selected text unidirectionally to a destination computer.

The Secure RS-232 Isolator permits unidirectional data flow from the serial port of one computer system to the serial port of another. Using the Secure RS-232 Isolator, control and monitoring commands and status events can be sent between two secure devices. The configurable Secure RS-232 Isolator permits the creation of rules, using regular expressions, to filter the information passed and to limit the type of events and commands that can pass through the isolator.
