1 and 2-port serial-to-WiFi (802.11a/b/g/n) device servers with wireless client

Product Feature

  • Links serial and Ethernet devices to an IEEE 802.11a/b/g/n network
  • Web-based configuration using built-in Ethernet or WLAN
  • Enhanced surge protection for serial, LAN, and power
  • Remote configuration with HTTPS, SSH
  • Secure data access with WEP, WPA, WPA2
  • Fast roaming for quick automatic switching between access points
  • Offline port buffering and serial data log
  • Dual power inputs (1 screw-type power jack, 1 terminal block)

Introduction

The NPort® W2150A and W2250A are the ideal choice for connecting your serial and Ethernet devices, such as PLCs, meters, and sensors, to a wireless LAN. Your communications software will be able to access the serial devices from anywhere over a wireless LAN. Moreover, the wireless device servers require fewer cables and are ideal for applications that involve difficult wiring situations. In Infrastructure Mode or Ad-Hoc Mode, the NPort® W2150A and NPort® W2250A can connect to Wi-Fi networks at offices and factories to allow users to move, or roam, between several APs (access points), and offer an excellent solution for devices that are frequently moved from place to place.
