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 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 Wi-Fi networks at offices and factories allow users to move, or “roam,” between several APs (Access Points). Moxa’s Fast Roaming function 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. can communicate with any host computer through an access point, or with another NPort® W2150A or NPort® W2250A located up to 100 meters away. increases the roaming speed to unify AP channels and avoid wasting channel hopping time while roaming.

Wireless Client For mission-critical applications, data from the serial device must not be lost if the wireless connection goes down. The NPort® W2150A and NPort® W2250A are 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 over 10 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 both the NPort® W2150A and NPort® W2250A is 64 KB per port. Offline Port Buffering and Serial Data Log for Each Port NPort® W2150A NPort® W2250A
