NPort W2150/2250 Plus:
First Wireless Device Server Supporting IEEE 802.11 a/b/g

The NPort W2150 Plus and NPort W2250 Plus are the ideal choice for connecting your serial 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 WLAN environment offers an excellent solution for applications that require moving devices from place to place.

• Features Link any serial device to an IEEE 802.11 a/b/g network RS-232/422/485 serial interfaces supported, at up to 921.6 Kbps Web-based configuration using built-in Ethernet or WLAN connection Enhanced remote configuration with HTTPS, SSH Secure data access with WEP, WPA, WPA2 Built-in WLAN site survey tool Wireless roaming with user-defined signal strength threshold Off-line port buffering and serial data log Dual power inputs ( power jack and terminal block)

• 802.11 a/b/g Wireless Connection to Serial Devices
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 W2150 Plus and W2250 Plus can communicate with any host computer through an access point, or with another NPort W2150 Plus or W2250 Plus up to 100 meters away.

• Wireless Roaming Function
Wi-Fi networks at offices and factories allow users to move, or "roam," between several APs (Access Points). The NPort W2150 Plus and W2250 Plus include a "Connect Rule" setting to allow wireless roaming.

The NPort W2150 Plus and W2250 Plus support 3 different connect rules.The servers can be configured to reconnect based on the signal strength of the AP. The threshold is selectable, so the server can be configured to reconnect to an AP when the signal strength is at 20%, 40%, 60%, or even 80%. You can set up three profiles on the NPort W2150 Plus or W2250 Plus. Wireless roaming can be configured based on the priorities that you define. You can also force the server to connect to only one AP by selecting “Fixed on first priority.”

• Off-line Port Buffering and Serial Data Log for Each Port
For mission-critical applications, data from the serial device must not be lost if the wireless connection goes down. The NPort W2150 Plus and W2250 Plus are designed to continue operating if the wireless connection is disconnected temporarily. When the wireless connection is restored, or if the connection fails, the serial data from the serial device will be queued in the 10 MB port buffer built into the device server. As soon as the wireless connection returns to normal, the data stored in the buffer will be sent to its destination. In addition, a serial data log can be enabled to make troubleshooting easier.

• Built-in WLAN Site Survey Tool
The NPort W2150 Plus and W2250 Plus have a built-in WLAN site survey tool to help users perform a wireless site survey. Additional software is not required to complete the site survey. The goal of a WLAN site survey is to supply enough information to determine how many access points are required, and where the access points should be placed. For most implementations, the number and placement of access points is designed to guarantee a minimum data rate. With wireless systems, it is often necessary to perform a WLAN site survey before installing the access points in order to understand completely the behavior of radio waves within the facility.

• Secure Remote Management and Configuration with SSH/SSL
Unauthorized access is one of the biggest headaches for system managers. In addition to IP filtering and password protection, the NPort W2150 Plus and W2250 Plus also support SSH and SSL to protect the NPort W2150 Plus and W2250 Plus from hackers. To transmit control messages securely, open the web console using a web browser that supports https (Explorer, for example). You may also open the serial or Telnet console using a terminal emulator that supports SSH, such as PuTTY.

• Any Serial Baudrate between 50 and 921.6 Kbps
Most device servers only support the most commonly used serial baud rates. However, some applications require special baudrates, such as 250 Kbps or 500 Kbps. With the NPort W2150 Plus and W2250 Plus, you can use any baudrate between 50 and 921.6 Kbps. Devices that use special baudrates will be able to connect properly to your network. If your baudrate is not a standard baudrate, select "other" from the drop-down list and simply enter the baudrate.
