NPort W2150A/W2250A Series Introduction
1-2
Overview
In this chapter we introduce the basic features and specifications of the NPort W2150A/W2250A and NPort
W2150A/W2250A-T, referred to collectively as the NPort W2150A/W2250A Series.
The NPort W2150A/W2250A Series of wireless device servers are used to connect RS-232/422/485 serial
devices such as PLCs, meters, and sensors, to a wired Ethernet LAN or wireless LAN. Your communications
software will be able to access the serial devices from anywhere over a local LAN, WLAN, or the Internet.
Moreover, the WLAN environment offers an excellent solution for applications in which the serial devices are
moved frequently from place to place.
The NPort W2150A/W2250A supports both automatic IP configuration protocols (DHCP, BOOTP) and manual
configuration using a standard web browser. Both IP configuration methods ensure quick and effective
installation. In addition, a utility called “NPort Windows Driver Manager” makes port mapping easy.
The external antenna can be adjusted for maximum signal strength. You can also choose to use your own
antenna for additional flexibility and scalability. A signal strength indicator on the front panel makes it easier for
you to troubleshoot any connection problems.
The NPort W2150A/W2250A Series offers different operation modes to ensure compatibility with standard
network APIs, including TCP Server Mode, TCP Client Mode, and UDP Mode. RealCOM/TTY drivers are provided
to allow legacy serial-based software to communicate over an IP network instantly. This preserves your
software investment while providing all the advantages of networking your serial devices.
For easier management, the NPort W2150A/W2250A include features such as password authentication, IP
filtering, 64-bit and 128-bit WEP encryption, and SNMP support.
