Terminal Servers
NPort
®
6600 Series
8/16/32-port RS-232/422/485 rackmount secure terminal servers
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. Security breaches are intolerable and the NPort®
6600 ensures data transmission integrity with support of DES, 3DES,
and AES encryption algorithms. 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.
The NPort® 6600 has a built-in LCD panel for configuration. The
panel displays the server name, serial number, and IP address, and
any of the device server’s configuration parameters, such as IP
address, netmask, and gateway address, can be updated easily and
quickly.
Note: The LCD panel is only available with standard temperature models.
The NPort® 6600 provides adjustable termination, pull high, and
pull low resistors for RS-485 communication. In some critical
environments, termination resistors may be needed to prevent the
reflection of serial signals, and the pull high and pull low resistors may
need adjusting to maintain the integrity of the electrical signal. Since
no set of resistor values works for every environment, the NPort®
6600 allows manual adjustment of the resistor values for each serial
port using built-in DIP switches.
