Antaira STE-604C Industrial 4-port RS232/422/485 to 2-port Fast Ethernet Industrial Device Server

The STE-604C is an innovative 4 port RS232/422/485 to 2-port Fast Ethernet TCP/IP) device server. To assure the agility and security of critical data, the STE-604C offers many powerful features for HW & SW redundant functions. When the connection between the master-link and LAN fails, the STE-604C can automatically switch to another LAN port within 10ms and still guarantee a non-stop connection. The STE-604C also supports switch mode. Users can Daisy Chain to reduce the usage of Ethernet switch ports. Secondly, the STE-604C can simultaneously transfer data into 5 host PCs. This feature can assure all critical data is saved in different host PCs to avoid Ethernet break or host PC failure. Thirdly, the STE-604C provides dual redundant power inputs on the DC power jack and terminal block. The unit provides a NAT pass through function so that users are able to manage their STE-604C inside or outside the NAT router. It is also easy for different IP domain users to use the STE-604C. The STE-604C is one of the best communication redundant solutions for any serial RS232, RS422 or RS485 device application.
