Secure Serial Servers – NPort 6000 Series

The NPort 6000 secure servers are able to transmit serial data with the highest encryption to an Ethernet network using a variety of operation modes— Secure TCP Server, Secure TCP Client, Secure Pair-Connection, Secure Real COM, and Secure Terminal modes.  (Click here for more information about operating mode.) NPort 6000 series are  IEC 62443-4-2 compliant.

Here are 3 key features how NPort 6000 series secure your date.

Secure Data Transmission

The NPort 6000 secure servers use SSL to implement secure data transmission for Secure TCP Server, Secure TCP Client, Secure Pair Connection, and Secure Real COM modes. The NPort’s drivers follow the SSL standard and automatically negotiate the encryption key. To prevent hacker attacks, the NPort will automatically switch from DES/3DES to AES encryption.

Zero Data Loss if Ethernet Connection Fails

The NPort 6000 provides exceptionally reliable data transmission by saving serial data to an internal 64 KB port buffer if the Ethernet connection fails. When the Ethernet network is reconnected, data in the buffer is automatically released and sent to the appropriate destination. For the NPort 6250, 6450, and 6650, this buffer can be expanded by installing an SD card.

Ethernet Ring Topology with Fast Recovery (NPort 6450/6600 only)

NPort 6000 secure terminal servers support the Turbo Ring protocol for cascade topologies. With Turbo Ring, if any segment of the daisy-chain ring is disconnected, the network will recover in less than 300 ms.
