Easy-to-use Industrial Serial
Device Server for
Distributed Applications |
Overview
|
| |
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.
