Seriallink SLK-S508D Serial Device Server is a multi-channel decentralized device with low-speed, different standards converted into Ethernet for centralized management. After installing virtual serial port, remote reading of serial data can be achieved. SLK-S508D Series Serial Device Server supports a variety of working modes, including TCP server mode, TCP client mode, UDP mode, TCP/UDP Socket, TCP Realport and other working modes, allowing user software to access serial devices through TCP plus port number. In addition, virtual serial port is also supported to access serial devices. Seriallink SLK-S508D supports easy and fast manual configuration of IP addresses through browsers or Telnet terminals. At the same time, users can automatically search serial device server in local area network through simple and easy-to-use Windows management software, and carry out remote configuration management and work status monitoring applications.
