B&B Electronics Manufacturing: Wi-Fi Access Point for Industrial M2M Applications
Two versions are available: the embeddable APMG-Q551 allows OEMs to WiFi-enable their own products so they can either serve as M2M wireless communications hubs or tie into existing wireless networks; the APXG-Q5420 external Ethernet access point provides the same functionality in a stand-alone box, and adds serial device server capability as well. The units allow an access-point-equipped device to become the center of its own self-sufficient Wi-Fi network. The external access point has an Ethernet port, plus two serial ports and can be configured as a router or network bridge. Its serial interfaces support RS232/422/485 legacy devices, and both ports can be used simultaneously. With the ability to connect and route between any of its ports, the unit can serve as an access point (handling up to eight simultaneous client connections) or as a bridge (tying Wi-Fi devices into Ethernet networks), while simultaneously serving as a serial device server (bridging serial devices into either wired or wireless LANs.). Units can switch easily from access point to client mode through either web or command line interfaces. In client mode the devices provide WPA2-Enterprise Class Extensible Authentication Protocols (EAP) with support for authentication Certificates.
