PortServer® TS M MEI
Serial Server – Modem Series
Ethernet and RS-232/422/485 serial connections,
with internal modem for dial-up connectivity to remote
serial devices.

PortServer TS M MEI offers Ethernet and RS-232/422/485
serial connections, with the addition of an internal modem.
The one- and 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 log-in
via a TCP/IP network for easy troubleshooting, monitoring,
configuration or control.
