Features and Functions

Thank you for purchasing one of Digi International's PortServer II family of commu-
nications and terminal servers. PortServer II allows you to connect up 16 serial
devices to a single TCP/IP Ethernet network port. Up to 48 additional devices (64
total) can be added by the connection of external expansion modules. You can attach a
variety of serial devices, including PCs, Internet links, asynchronous terminals, print-
ers, ISDN terminal adapters, and modems. You can also attach parallel devices such
as printers, if you use an expansion module with a parallel port. Because PortServer II
is independent of the hardware connected to it, users can access any type of networked
server running the TCP/IP protocol suite.
A system configuration diagram with many of PortServer II features in use is shown
