The STE-516C is a serial-to-Ethernet device server that consists of 2 x 10/100 Mbps LAN ports and 16 combo RS-232/RS-422/RS-485 serial ports. The STE-516C features a built-in powerful ARM9G20 (400 MHz) processor that provides a maximum serial transfer rate of up to 921.6 kbps. The STE-516C can be applied in many serial applications from manufacturing plant, factory and industry as well as building automation, etc.

Network Communication with Diverse Protocols Supported
The STE-516C device server provides an easy way to enable RS-232, RS-422 and RS-485 serial devices to be Ethernet LAN/WAN ready devices. The STE-516C also provides Web GUI configuration, allowing you to easily configure the device server and serial devices. Furthermore, the STE-516C features a “COM port redirection” function enabling serial communication without socket programs. Various network protocols are supported by the STE-516C including TCP, UDP, Telnet, ICMP, DHCP, TFTP, HTTP, SNMP 1/2/3, SSH and SSL. In addition, server mode, client mode, and virtual serial port mode enable the STE-516C to connect, communicate, and exchange data with user application programs via various methods.

All-Purpose Software and Programs
Useful software such as COM Port Redirector and PortView are provided with the STE-516C to help facilitate the use of the device server. COM Port Redirector is a software installed on a computer for automatic serial to LAN conversion. As COM Port Redirector is applied, the serial ports of the STE-516C connected through a network can be used as if the serial ports in STE-516C were COM ports from the user’s computer. PortView, however, is a program of real-time monitoring of communication status for the STE-516C. From the remote site, users can monitor all input, output data, and the communication status of the STE-516C via each serial port on a Windows operating system.
