PortServer TS serial servers offer RS-232 serial port expansion, making it easy to connect any serial device to your network. Available in 1, 2, or 4-port models, these serial servers combine the inherent benefits of data networking with proven asynchronous connectivity. They deliver powerful, yet simple Ethernet connectivity for all your serial devices.
PortServer TS device servers are ideal for applications requiring COM ports or where TCP/UDP Sockets or multicast functionality is required. All Digi device servers include Digi√És patented RealPort√É COM port redirector technology, which makes it possible to establish a connection between the host and networked serial device by creating a local COM or TTY port on the host computer, allowing existing software applications to work without modification.
