NPort Server Lite
1/2/4 Ports Industrial Serial Device Server for 100M Ethernet
Features
NPort Server Lite
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 like CNCs, PLCs, weighing
scales, scanners and other devices directly to the 10/100M
Ethernet network running TCP/IP.
Through the revolutionary built-in human interface with
Liquid Crystal Module (LCM) for displaying data/status
and buttons for inputting data or selecting mode, you can
easily set up the server, such as IP address, net mask, and
gateway, and monitor the server status and data
transmission. Eliminate the need to prepare additional PCs
during installation.
In addition to allowing serial devices to get networked,
any host (PC Server or Workstation) without network
access can also access remote serial device via adding
NPort Server Lite to the existing serial port. In other word,
a pair of 1-port NPort Server Lites can be configured over
Ethernet and serve as a transparent serial channel without
platform and distance limitation.
