The NPort 6650-16 device server is the right choice for applications that use large numbers of serial devices packed into a small space. Security breaches are intolerable and the NPort 6650-16 ensures data transmission integrity with support of DES, 3DES, and AES encryption algorithms. Serial devices of any type can be connected to the NPort 6650-16, and each serial port on the NPort can be configured independently for RS-232, RS-422, or RS-485 transmission.
