Advantech’s EKI-1351 (1-port) and EKI-1352 (2-port) 802.11b/g device servers allow most RS232/422/485 serial devices to be remotely monitored, managed, and controlled wirelessly, eliminating the need for hard-wired cable connections.
Device servers are a drop-in solution to add network connectivity to non-networked devices and equipment. With one connection for the network, and the other for attached RS232/422/485 serial devices, device servers encapsulate serial data for transport over Internet Protocol (IP) networks. Used together in pairs as an extension cable for serial devices, or separately with a host computer or PC, they are an ideal solution to overcome the inherent distance limitations and point-to-point nature of serial devices.
For easy integration with COM port-based Windows applications, the included COM port redirection software allows virtual COM port access to remote serial devices, just as if they were onboard COM ports. With this tool, integration with PC-based systems takes just a few minutes, and it is transparent to the host application software and connected equipment.
In addition to virtual COM port operation, the EKI-1351 and EKI-1352 support TCP/IP and UDP/IP applications such as OPC servers and HMI systems that support serial encapsulation. For simple applications, these units can be used in a peer-to-peer manner, where there is no need for wireless infrastructure or access points. For more advanced applications, both client and server modes are supported, in support of serial device initiated or host initiated communications.
