WF7202: Bộ chuyển đổi RS-232 sang Wi-Fi/Ethernet

Description

The serial device networking (TCP/IP) has become a trend of industrial on-site networking. However, the on-site wiring construction and alternation cost have always been a bottle neck of serial device networking. With the growingly mature WLAN technology and falling cost of related hardware, the advantage of serial device networking has become quite obvious, which makes serial device wireless networking a must.
WF7202 wireless serial port server offers wireless transceiver and high speed serial port, conforming to IEEE802.11b/g wireless network communication standard. The maximum standard transmission distance is 300M and further wireless communication can be achieved by additional high gain external antenna, which can not only prevent difficult wiring but also lower construction cost, specially suitable for devices like industrial environment and factory automation system, on-site monitoring system, etc.
