Moxa NPORT 5210A RS-232 serial server

10/100 Mbps, RS-232, metal, 340g Standard TCP/IP Protocols and Choice of Operation Modes
NPort 5200 device servers can operate in TCP Server, TCP Client, or UDP operation mode, ensuring compatibility with software based on a standard network API (Winsock, BSD Sockets).

Real COM/TTY Drivers for Existing Software
With the Real COM/TTY drivers that are provided with each NPort, software designed for communication with COM/TTY ports can be instantly and seamlessly integrated into a TCP/IP network. This is a excellent " no fuss" way to preserve your software investment and enjoy the benefits of networking your serial devices.

Control Remote Serial Devices with TCP/IP or Traditional COM/TTY Port
By specifying the NPort 5200's IP address and port number, a network sockets API can obtain access to the attached serial device over the network, from any host computer that supports TCP/IP. For legacy Windows or Linux software that is COM or TTY-based, Moxa’s COM/TTY drivers provide a seamless way of operating over the network.
