Das NPort W2150A/W2250A ist die ideale Lösung, um Ihre seriellen Geräte wie z.B. SPS-Systeme, Messgeräte und Sensoren mit einem WLAN-Netzwerk zu verbinden.
So kann Ihre Kommunikationssoftware über ein WLAN von überall her auf die seriellen Geräte zugreifen. Außerdem erfordern die Wireless-Geräteserver weniger Kabel und eignen sich hervorragend für Anwendungen in schwierigen Verkabelungssituationen. Im Infrastruktur-Modus oder Ad-Hoc-Modus kann sich der NPort W2150A/W2250A mit WLANs in Büros und Fabriken verbinden, um es Anwendern ermöglichen, zwischen mehreren Access Points zu wechseln ("roamen"). Somit ist NPort W2150A/W2250A eine hervorragende Lösung für Geräte, die häufig zwischen Standorten bewegt werden.
802.11a/b/g Wireless Connectivity 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® W2150A can communicate with any host computer through an access point, or with another NPort® W2150A located up to 100 meters away.
Wireless Fast Roaming Function Wi-Fi networks at offices and factories allow users to move, or “roam,” between several APs (Access Points). Moxa’s Fast Roaming function increases the roaming speed to unify AP channels and avoid wasting channel hopping time while roaming.
Wireless Client Ethernet to Wifi function is supported. Data can be seamlessly transferred between the serial line, LAN, and WLAN.
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® W2150A is designed to continue operating if the wireless connection is disconnected temporarily. If the wireless connection is restraining, or if the connection fails, the serial data from the serial device will be queued in the built-in port buffer with 20 MB of storage. 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.
The serial data log buffer for the NPort® W2150A is 64 KB per port.
Built-in WLAN Site Survey Tool The NPort® W2150A has a built-in WLAN site survey tool. Additional software is NOT required to complete the site survey.
The purpose of conducting a WLAN site survey is 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 how radio waves behave within the facility.
Secure Remote Management and Configuration with SSH/HTTPS Unauthorized access is one of the biggest headaches for system managers. In addition to IP filtering and password protection, the NPort® W2150A also support SSH and HTTPS to provide protection from hackers. To transmit control messages securely, open the web console using a web browser that supports https (Internet Explorer, for example). You may also open the serial or Telnet console, such as PuTTY, using a terminal emulator that supports SSH.
Select “Any Baudrate” between 50 bps and 921.6 kbps Most device servers only support a fixed number of serial baudrates. However, some applications require special baudrates, such as 250 kbps or 500 kbps. With the NPort® W2150A, you can enter any baudrate between 50 and 921.6 kbps. If your device’s baudrate is not a standard baudrate, select “other” from the drop-down list and then enter the baudrate.
