General Details

Introduction of RS232 to Ethernet Converters

The RS232 to Ethernet Converters, used for data transparent transmission. USR-TCP232-302 is a low-cost serial device server,whose function is to realize bidirectional transparent transmission between RS232 and Ethernet. USR-TCP232-302 is internally integrated with TCP/IP protocol. User can apply it to device networking communication.
