Black Box LES421A-R2 Industrial RS232/422/485 Serial Device Server, 1-Port

Black Box LES421A-R2 One Port RS232/422/485 Industrial Serial Device Server

The LES421A-R2 Industrial RS-232/422/485 Serial Device Server features two independent Ethernet ports and MAC addresses to provide a redundant network mechanism that guarantees Ethernet network reliability. It is designed to connect RS-232/422/485 serial devices such as PLC, meters, sensors, and barcode readers to an IP-based Ethernet LAN. It allows nearly any device with serial ports to connect and share an Ethernet network, while also 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, it ensures compatibility in network software using a standard network API. Moreover, serial devices can be made communicate with other devices via peer-to-peer, thus eliminating the need for an intermediate host PC and software programming.
