EKI-1351The EKI-1351 is a single port wireless serial device server that bring RS-232/422/485 to wireless Ethernet. It allows nearly any device with serial ports to connect and share a Wireless Ethernet network. The EKI-1351 provides a quick, simple and cost-effective way to bring the advantages of remote management and data accessibility to thousands of devices that cannot connect to a network.
With the EKI-1351 your existing serial devices can be used with the most popular operating systems on the market. There is no need to write special drivers for specific operating systems. Moreover, you can make serial devices communicate with other devices peer-to-peer, without any intermediate host PCs and software programming. That saves a lot of cost and effort. In addition, you can actively request data or issue commands from the RS-232/422/485 side or Wireless Ethernet side. This data can be sent bilaterally. Thus, the EKI-1351 is especially suitable for remote monitoring environments such as security systems, factory automaton, SCADA, transportation and more.
