The NPort 6600 series of secure device servers is the right choice for applications that use large numbers of serial devices packed into a small space. If you're worried about security, you can rest assured with the NPort 6600, since it supports DES, 3DES, and AES, the three most common standards for data encryption. Serial devices of any type can be connected to the NPort 6600, and each serial port on the NPort can be configured independently for RS-232, RS-422, or RS-485 transmission.
