The 2-port NPort® 6250 device servers use the SSL and SSH protocols
to transmit encrypted serial data over Ethernet. Models are available
for connecting to a 10/100BaseTX copper Ethernet or 100BaseTX fiber
network. Both single-mode and multi-mode fiber are supported.
Zero Data Loss if Ethernet Connection Fails
The NPort® 6250 device servers help guarantee reliability by
providing users with secure serial-to-Ethernet data transmission and a
customer-oriented hardware design. If the Ethernet connection fails,
the NPort® 6250 will queue all serial data in its internal 64 KB port
buffer. When the Ethernet connection is re-established, the NPort®6250
will immediately release all data in the buffer in the order that it
was received. Users can increase the port buffer size by installing an
SD card.
