6450

The NPort® 6450 is a 4-port device server that uses the SSL and
SSH protocols to transmit encrypted serial data over Ethernet. Up to 4
serial devices of any type can be connected to the NPort® 6450, with

The NPort® 6450 is a reliable device server that provides users with
secure serial-to-Ethernet data transmission and a customer-oriented
hardware design. If the Ethernet connection fails, the NPort® 6450 will
queue all serial data in its internal 64 KB port buffer. When the Ethernet

configured for a normal or secure TCP/IP connection.

connection is re-established, the NPort® 6450 will immediately
release all data in the buffer in the order that it was received. Users can
increase the port buffer size by installing a SD card.
