The EKI-1528I and EKI-1528CI feature two independent Ethernet Ports and MAC adresses to provide a redundant network mechanism to guarantee Ethernet network reliability. The EKI-1528I and EKI-1528CI are serial device server that connect RS-232/422/485 serial devices,such as PLC, meters,sensors and barcode reader to an IP- based Ethernet LAN. They allow nearly any device with serial ports to connect and share an Ethernet Network. The EKI-1528i and EKI-1528CI provide various operations: COM port redirection (Virtual COMport), TCP Server TCP Client and UDP Mode. With COM port redirection mode, standard serial operation calls are transparently redirected to the EKI-1528I and EKI-1528CI,guaranteeing compatibility with legacy serial devices and enabling backward compatibility with existing software. With TCP Server, TCP Client and UDP modes, EKI-1528I and EKI-1528CI ensure the compatibility of network software that uses a standard network API. Moreover you can make serial devices peer-to-peer, without any intermediate host PCs and software programming.
