Serial-to-Ethernet Device Servers
Unauthorized access is one of the biggest headaches for system
managers. In addition to IP filtering and password protection, the
NPort® W2150A and NPort® W2250A also support SSH and HTTPS
to provide protection from hackers. To transmit control messages
securely, open the web console using a web browser that supports
https (Internet Explorer, for example). You may also open the serial or
Telnet console, such as PuTTY, using a terminal emulator that supports
SSH.
Most device servers only support a fixed number of serial baudrates.
However, some applications require special baudrates, such as 250
