Serial Device Server


Advantech EKI-1524ci 4-Port RS-232/422/485 Industrial Serial Device Server with Wide Operating Temperature & Isolation


SKU: EKI-1524CI-CE Category:

The EKI-1521, EKI-1522 & EKI-1524 feature two independent Ethernet ports and MAC addresses to provide a redundant network mechanism that guarantees Ethernet network reliability with design to connect RS-232/422/485 serial devices such as PLC, meters, sensors, and barcode readers to an IP-based Ethernet LAN. They allow nearly any device with serial ports to connect and share an Ethernet network, providing various operations such as 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 servers, guaranteeing compatibility with legacy serial devices and enabling backward-compatibility with existing software. With TCP server, TCP client, and UDP modes, the EKI- 1521, EKI-1522, and EKI-1524 ensure compatibility in network software using a standard network API and can be made communicate with other devices via peer-to-peer, eliminating the need for an intermediate host PC and software programming.
