The PortServer TS H MEI family of serial servers is designed specifically for utility plants, pipelines, traffic management facilities or any remote application requiring a hardened serial-to-Ethernet solution that can withstand extreme temperatures. Available in one-, two-, or four-port models, PortServer TS H MEI makes it easy to network-enable and remotely manage variable message signs, loop detectors, ramp meters or any RS-232/422/485 serial device.

Digi's patented RealPort® COM port redirector technology 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. PortServer TS H MEI also delivers data security via SSHv2, full SNMP device management, and industry-leading low latency.
