The NPort Server
Lite Series is an industrial-strength, network-based serial device
server for connecting up to four RS-232 or RS-422/485 devices, such
as CNCs, PLCs, weight scales, and scanners, directly to a 10/100 Mbps
Ethernet network running TCP/IP.
The NPort Server
Lite Series has a revolutionary built-in human-machine LCM interface
for displaying configuration parameters. This includes buttons for
inputting data or for selecting the mode, and allows easy setup of
the server, such as IP addresses, net mask, and gateway address. Furthermore,
it can also monitor server status and data transmission, eliminating
the need to prepare additional PCs during installation.
In addition to
allowing serial devices to be networked, any PC Server or Workstation
host without network access can be set up to allow access to remote
serial devices by adding NPort Server Lite to its existing serial
port. In other words, a pair of 1-port NPort Server Lites can be configured
over the Ethernet and serve as a transparent serial channel without
platform and distance limitations.
