Quatech 1Port Serial Device SVR with

EKI-1521 features two independent Ethernet ports and MAC addresses to provide a redundant network mechanism to guarantee Ethernet network reliability. EKI-1521 is serial device servers that connect RS-232/422/485 serial devices, such as PLC, meters, sensors, and barcode reader to an IP-based Ethernet LAN. It allows nearly any device with serial ports to connect and share an Ethernet network. EKI-1521 provides various operations: COM port redirection (virtual COM port), TCP Server, TCP Client and UDP mode. With COM port redirection mode, standard serial operation calls are transparently redirected to the EKI-1521, guaranteeing compatibility with legacy serial devices and enabling backward compatibility with existing software. With TCP server, TCP client, and UDP modes, EKI-1521 ensures the compatibility of network software that uses a standard network API. Moreover, you can make serial devices communicate with other devices peer-to-peer, without any intermediate host PCs and software programming.
Advantech serial device servers and Modbus/Fieldbus gateways are serial-to-Ethernet solutions that allow users to connect their isolated serial devices to the Internet for centralized machine communication management. Advantech high compatibility device servers and Modbus/Fieldbus gateways can seamlessly convert protocols for boundless machine-to-machine/machine-to-cloud data transmission and network connectivity. The obstacles of versatile protocol communication no longer exist!
