Moxa NPort W2250A-W4-US - 2-port RS-232/422/485 wireless device server with 802.11a/b/g/n WLAN US band, US plug
by MOXA

The NPort® W2150A-W4 and W2250A-W4 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, the NPort® W2150A-W4 and NPort® W2250A-W4 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.
