The new PortServer TS M MEI family offers Ethernet and RS-232/422/485 serial connections, with the addition of an internal modem. The one- and three-port device 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 a device 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.
