PortServer® TS M MEI offers Ethernet and RS-232/422/485 serial connections, with the addition of an internal modem. The three-port serial servers are ideal for applications requiring both IP networking and standard phone line dial-up connectivity for remote access to serial devices.

The embedded modem adds another level of flexibility to the PortServer TS line. It allows remote hosts to dial-in to a serial device attached to the Digi serial server, as well as the serial device to dial-out to a remote location using a standard phone line. The modem helps to create a PPP connection (TCP/IP connection over modem) so that applications and devices can communicate via an IP network, even when the primary LAN or WAN is not available. This allows users from a central location to maintain access to remote serial devices.

Other applications for PortServer TS M MEI include remote site console management for small branches and remote login via a TCP/IP network for easy troubleshooting, monitoring, configuration or control.
