Digi PortServer TS MEI (Multi-Electrical Interface) serial servers offer RS-232/422/485 serial port expansion, making it easy to connect any serial device to your network. Available in one-, two-, four-, eight- or 16-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 MEI device servers deliver universal and powerful features including data security via SSHv2, port buffering, and full SNMP management, making them ideal for serial port expansion application including manufacturing floor, gas pumps and industrial automation, where device management and monitoring are critical.

All Digi device servers include Digi’s patented RealPort® 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.
